The Centers for Disease Control and Prevention updated its domestic travel guidance for fully vaccinated people on Friday, lifting certain requirements while continuing to advise mitigation measures like mask-wearing and hand-washing.

The Centers for Disease Control and Prevention has updated its domestic travel guidance for fully vaccinated people, lifting certain testing and self-quarantine requirements and recommending precautions like wearing a mask and avoiding crowds. But health officials continue to discourage nonessential travel, citing a sustained rise in cases and hospitalizations.

The CDC updated its website on Friday to reflect the latest scientific evidence, writing that "people who are fully vaccinated with an FDA-authorized vaccine can travel safely within the United States."

The announcement comes less than a month after the CDC first released updated guidance about gatherings for fully vaccinated people, which it described as a "first step" toward returning to everyday activities.

Air Travel Is Opening Up Again, But That Doesn't Mean The Pandemic Is Over

The CDC considers someone fully vaccinated two weeks after they receive the last dose of vaccine. Those individuals will no longer need to get tested before or after travel unless their destination requires it, and do not need to self-quarantine upon return.

The new guidance means, for example, that fully vaccinated grandparents can fly to visit their healthy grandkids without getting a COVID-19 test or self-quarantining as long as they follow other recommended measures while traveling, according to CDC Director Rochelle Walensky.

Those measures include wearing a mask over their nose and mouth, staying 6 feet from others and washing their hands frequently. Masks are required on all planes traveling into, within or out of the U.S., under an executive order issued by President Biden.

But Walensky, speaking at a White House COVID-19 Response Team briefing on Friday, nonetheless discouraged all nonessential travel, citing a continued increase in the seven-day average of cases and hospitalizations.

"While we believe that fully vaccinated people can travel at low risk to themselves, CDC is not recommending travel at this time due to the rising number of cases," Walensky said.

CDC Director Fears 'Impending Doom' If U.S. Opens Too Quickly

She said that while vaccinated people can do more things safely, most Americans are not yet fully vaccinated. Those who are not must have a negative test 1-3 days before they travel under CDC guidance. They must either get tested 3-5 days after they return and self-quarantine for 7 days, or self-quarantine for 10 days with no test.

Walensky said on Monday that there is more travel occurring now than throughout the pandemic, including the winter holidays. She acknowledged that people have been looking to get away over spring break or take advantage of what they perceive as a "relative paucity in cases," and she said the country was seeing an uptick in cases as a result.

"The thing that's different this time is that we actually have it in our power to be done with the scale of the vaccination," she said. "And that will be so much slower if we have another surge to deal with as well."

The U.S. is already seeing an uptick in domestic travel, and many Americans are looking to book trips in the coming months in what experts described to NPR as a sign of "clear pent up demand for travel."

As the country's supply of COVID-19 doses has grown, so has Biden's goal for the number of shots in arms during his first 100 days, doubling the target to 200 million by the end of this month. Many states have already expanded eligibility to all adults or are set to do so in the coming weeks, well ahead of the president's May 1 deadline.

According to NPR's vaccine tracker , 16.9% of the U.S. population is fully vaccinated, and 30% has had at least one dose. Researchers estimate that 70% to 85% of the country would need to have immunity for COVID-19 to stop spreading through communities.

International travel restrictions remain

The CDC is not lifting travel restrictions barring the entry of most non-U.S. citizens from places including China, Brazil, South Africa and parts of Europe. It will continue to require airline passengers entering the U.S. to get a test within three days of their departure and show proof of a negative result before boarding.

The travel industry has been pushing for some of these restrictions to end. A group of 26 organizations sent a letter to White House COVID-19 czar Jeffrey Zients urging the federal government "to partner with us to develop, by May 1, 2021, a risk-based, data-driven roadmap to rescind inbound international travel restrictions."

While Some Spring Breakers Swarm Beaches, Many Stay Home, Dreaming Of Summer Travel

"To be clear, at this time, we do not support removal or easing of core public health protections, such as the universal mask mandate, inbound international testing requirement, physical distancing or other measures that have made travel safer and reduced transmission of the virus," they wrote. "However, the data and science demonstrate that the right public health measures are now in place to effectively mitigate risk and allow for the safe removal of entry restrictions."

Travel and tourism have taken a considerable hit because of the pandemic with industry groups noting that overseas travel to the U.S. declined by 81% in 2020, causing billions of dollars in losses. Without lifting international travel bans, the U.S. Travel Association estimates that some 1.1 million American jobs will not be restored and billions in spending will be lost by the end of the year.

"Fortunately, enough progress has been made on the health front that a rebound for domestic leisure travel looks possible this year, but that alone won't get the job done," Roger Dow, the association's president and CEO, said in a statement . "A full travel recovery will depend on reopening international markets, and we must also contend with the challenge of reviving business travel."

Fauci Expects Surge In Vaccinations To Keep A 4th Coronavirus Wave At Bay

• Centers for Disease Control and Prevention
• COVID-19 vaccine

• COVID-19 travel advice

Considering travel during the pandemic? Take precautions to protect yourself from COVID-19.

A coronavirus disease 2019 (COVID-19) vaccine can prevent you from getting COVID-19 or from becoming seriously ill due to COVID-19 . But even if you're vaccinated, it's still a good idea to take precautions to protect yourself and others while traveling during the COVID-19 pandemic.

If you've had all recommended COVID-19 vaccine doses, including boosters, you're less likely to become seriously ill or spread COVID-19 . You can then travel more safely within the U.S. and internationally. But international travel can still increase your risk of getting new COVID-19 variants.

The Centers for Disease Control and Prevention (CDC) recommends that you should avoid travel until you've had all recommended COVID-19 vaccine and booster doses.

Before you travel

As you think about making travel plans, consider these questions:

• Have you been vaccinated against COVID-19 ? If you haven't, get vaccinated. If the vaccine requires two doses, wait two weeks after getting your second vaccine dose to travel. If the vaccine requires one dose, wait two weeks after getting the vaccine to travel. It takes time for your body to build protection after any vaccination.
• Have you had any booster doses? Having all recommended COVID-19 vaccine doses, including boosters, increases your protection from serious illness.
• Are you at increased risk for severe illness? Anyone can get COVID-19 . But older adults and people of any age with certain medical conditions are at increased risk for severe illness from COVID-19 .
• Do you live with someone who's at increased risk for severe illness? If you get infected while traveling, you can spread the COVID-19 virus to the people you live with when you return, even if you don't have symptoms.
• Does your home or destination have requirements or restrictions for travelers? Even if you've had all recommended vaccine doses, you must follow local, state and federal testing and travel rules.

Check local requirements, restrictions and situations

Some state, local and territorial governments have requirements, such as requiring people to wear masks, get tested, be vaccinated or stay isolated for a period of time after arrival. Before you go, check for requirements at your destination and anywhere you might stop along the way.

Keep in mind these can change often and quickly depending on local conditions. It's also important to understand that the COVID-19 situation, such as the level of spread and presence of variants, varies in each country. Check back for updates as your trip gets closer.

Travel and testing

For vaccinated people.

If you have been fully vaccinated, the CDC states that you don't need to get tested before or after your trip within the U.S. or stay home (quarantine) after you return.

If you're planning to travel internationally outside the U.S., the CDC states you don't need to get tested before your trip unless it's required at your destination. Before arriving to the U.S., you need a negative test within the last day before your arrival or a record of recovery from COVID-19 in the last three months.

After you arrive in the U.S., the CDC recommends getting tested with a viral test 3 to 5 days after your trip. If you're traveling to the U.S. and you aren't a citizen, you need to be fully vaccinated and have proof of vaccination.

You don't need to quarantine when you arrive in the U.S. But check for any symptoms. Stay at home if you develop symptoms.

For unvaccinated people

Testing before and after travel can lower the risk of spreading the virus that causes COVID-19 . If you haven't been vaccinated, the CDC recommends getting a viral test within three days before your trip. Delay travel if you're waiting for test results. Keep a copy of your results with you when you travel.

Repeat the test 3 to 5 days after your trip. Stay home for five days after travel.

If at any point you test positive for the virus that causes COVID-19 , stay home. Stay at home and away from others if you develop symptoms. Follow public health recommendations.

Stay safe when you travel

In the U.S., you must wear a face mask on planes, buses, trains and other forms of public transportation. The mask must fit snugly and cover both your mouth and nose.

Follow these steps to protect yourself and others when you travel:

• Get vaccinated.
• Keep distance between yourself and others (within about 6 feet, or 2 meters) when you're in indoor public spaces if you're not fully vaccinated. This is especially important if you have a higher risk of serious illness.
• Avoid contact with anyone who is sick or has symptoms.
• Avoid crowds and indoor places that have poor air flow (ventilation).
• Don't touch frequently touched surfaces, such as handrails, elevator buttons and kiosks. If you must touch these surfaces, use hand sanitizer or wash your hands afterward.
• Wear a face mask in indoor public spaces. The CDC recommends wearing the most protective mask possible that you'll wear regularly and that fits. If you are in an area with a high number of new COVID-19 cases, wear a mask in indoor public places and outdoors in crowded areas or when you're in close contact with people who aren't vaccinated.
• Avoid touching your eyes, nose and mouth.
• Cover coughs and sneezes.
• Wash your hands often with soap and water for at least 20 seconds.
• If soap and water aren't available, use a hand sanitizer that contains at least 60% alcohol. Cover all surfaces of your hands and rub your hands together until they feel dry.
• Don't eat or drink on public transportation. That way you can keep your mask on the whole time.

Because of the high air flow and air filter efficiency on airplanes, most viruses such as the COVID-19 virus don't spread easily on flights. Wearing masks on planes has likely helped lower the risk of getting the COVID-19 virus on flights too.

However, air travel involves spending time in security lines and airport terminals, which can bring you in close contact with other people. Getting vaccinated and wearing a mask when traveling can help protect you from COVID-19 while traveling.

The Transportation Security Administration (TSA) has increased cleaning and disinfecting of surfaces and equipment, including bins, at screening checkpoints. TSA has also made changes to the screening process:

• Travelers must wear masks during screening. However, TSA employees may ask travelers to adjust masks for identification purposes.
• Travelers should keep a distance of 6 feet apart from other travelers when possible.
• Instead of handing boarding passes to TSA officers, travelers should place passes (paper or electronic) directly on the scanner and then hold them up for inspection.
• Each traveler may have one container of hand sanitizer up to 12 ounces (about 350 milliliters) in a carry-on bag. These containers will need to be taken out for screening.
• Personal items such as keys, wallets and phones should be placed in carry-on bags instead of bins. This reduces the handling of these items during screening.
• Food items should be carried in a plastic bag and placed in a bin for screening. Separating food from carry-on bags lessens the likelihood that screeners will need to open bags for inspection.

Be sure to wash your hands with soap and water for at least 20 seconds directly before and after going through screening.

Public transportation

If you travel by bus or train and you aren't vaccinated, be aware that sitting or standing within 6 feet (2 meters) of others for a long period can put you at higher risk of getting or spreading COVID-19 . Follow the precautions described above for protecting yourself during travel.

Even if you fly, you may need transportation once you arrive at your destination. You can search car rental options and their cleaning policies on the internet. If you plan to stay at a hotel, check into shuttle service availability.

If you'll be using public transportation and you aren't vaccinated, continue physical distancing and wearing a mask after reaching your destination.

Hotels and other lodging

The hotel industry knows that travelers are concerned about COVID-19 and safety. Check any major hotel's website for information about how it's protecting guests and staff. Some best practices include:

• Enhanced cleaning procedures
• Physical distancing recommendations indoors for people who aren't vaccinated
• Mask-wearing and regular hand-washing by staff
• Mask-wearing indoors for guests in public places in areas that have high cases of COVID-19
• Vaccine recommendations for staff
• Isolation and testing guidelines for staff who've been exposed to COVID-19
• Contactless payment
• Set of rules in case a guest becomes ill, such as closing the room for cleaning and disinfecting
• Indoor air quality measures, such as regular system and air filter maintenance, and suggestions to add air cleaners that can filter viruses and bacteria from the air

Vacation rentals, too, are enhancing their cleaning procedures. They're committed to following public health guidelines, such as using masks and gloves when cleaning, and building in a waiting period between guests.

Make a packing list

When it's time to pack for your trip, grab any medications you may need on your trip and these essential safe-travel supplies:

• Alcohol-based hand sanitizer (at least 60% alcohol)
• Disinfectant wipes (at least 70% alcohol)
• Thermometer

Considerations for people at increased risk

Anyone can get very ill from the virus that causes COVID-19 . But older adults and people of any age with certain medical conditions are at increased risk for severe illness. This may include people with cancer, serious heart problems and a weakened immune system. Getting the recommended COVID-19 vaccine and booster doses can help lower your risk of being severely ill from COVID-19 .

Travel increases your chance of getting and spreading COVID-19 . If you're unvaccinated, staying home is the best way to protect yourself and others from COVID-19 . If you must travel and aren't vaccinated, talk with your health care provider and ask about any additional precautions you may need to take.

Remember safety first

Even the most detailed and organized plans may need to be set aside when someone gets ill. Stay home if you or any of your travel companions:

• Have signs or symptoms, are sick or think you have COVID-19
• Are waiting for results of a COVID-19 test
• Have been diagnosed with COVID-19
• Have had close contact with someone with COVID-19 in the past five days and you're not up to date with your COVID-19 vaccines

If you've had close contact with someone with COVID-19 , get tested after at least five days. Wait to travel until you have a negative test. Wear a mask if you travel up to 10 days after you've had close contact with someone with COVID-19 .

What to Know About the C.D.C. Guidelines on Vaccinated Travel

In updated recommendations, the federal health agency said both domestic and international travel was low risk for fully vaccinated Americans. But travel remains far from simple.

• Share full article

By Ceylan Yeginsu

The Centers for Disease Control and Prevention updated its guidance for fully vaccinated Americans in April, saying that traveling both domestically and internationally was low risk.

The long-awaited recommendations were issued by federal health officials after a series of studies found that vaccines administered in the United States were robustly effective in preventing infections in real-life conditions.

One is considered fully vaccinated two weeks after receiving the single dose of the Johnson & Johnson vaccine, or two weeks after receiving the second dose of the Pfizer-BioNTech or Moderna shots.

If you decide to travel, you might still have some questions. Here are the answers.

Will I still need to wear a mask and socially distance while traveling?

Yes. Under federal law, masks must be worn at airports in the United States, onboard domestic flights and in all transport hubs. The C.D.C. says that as long as coronavirus measures are taken in these scenarios, including mask wearing, fully vaccinated Americans can travel domestically without having to take a test or quarantine, although the agency warns that some states and territories may keep their local travel restrictions and recommendations in place.

For those wishing to travel internationally, a coronavirus test will not be required before departure from the United States unless mandated by the government of their destination. Vaccinated travelers are still required to get tested three days before travel by air into the United States, and are advised to take a test three to five days after their return, but will not need to self-quarantine.

Can I go abroad?

Yes, but only to countries that will have you.

More than half the world’s countries have reopened to tourists from the United States, including the countries of the European Union , which on June 18 added the United States to its “safe list” of countries, meaning that American travelers can now visit. While the European Union aims to take a coordinated approach to travel this summer, member states will be allowed to set their own requirements for travelers from individual countries based on their own epidemiological criteria, which means they may require testing or vaccination.

Some places like Turkey, Croatia and Montenegro had already been welcoming Americans with negative test results. Greece joined that growing list in May, ahead of most European countries, opening to fully vaccinated tourists and other foreigners with a negative test.

Many Caribbean nations have reopened to American tourists, but each has its own coronavirus protocols and entry requirements.

Here’s a full list of countries Americans can currently travel to.

What about domestic travel? Is it free and clear to cross state borders?

If you are fully vaccinated, the C.D.C. says you can travel freely within the United States and that you do not need to get tested, or self-quarantine, before or after traveling. But some states and local governments may choose to keep travel restrictions in place, including testing, quarantine and stay-at-home orders. Hawaii , for instance, still has travel restrictions in place.

Before you travel across state lines, check the current rules at your destination.

How are they going to check that I’m fully vaccinated?

Right now, the best way to prove that you have been vaccinated is to show your vaccine card .

Digital vaccine and health certificates showing that people have been vaccinated or tested are in various stages of development around the world and are expected, eventually, to be widely used to speed up travel.

The subject of “ vaccine passports ” is currently one of the most hotly debated topics within the travel industry, with questions over the equity of their use and concerns over health and data privacy.

In early April, Gov. Ron DeSantis of Florida issued an executive order that would ban local governments and state businesses from requiring proof of vaccination for services.

And in March, the European Union endorsed its own vaccine certificate , which some countries are already using, with more expected to adopt it by July 1.

But what about my kids? What’s the guidance on traveling with unvaccinated people?

The C.D.C. advises people against travel unless they have been vaccinated. If you must travel, the agency recommends testing one to three days before a trip and following all coronavirus guidance at your destination.

In May, the F.D.A. expanded its emergency use authorization of the Pfizer-BioNTech coronavirus vaccine to include adolescents between 12 and 15 years of age.

All air passengers aged two and older coming into the United States, including fully vaccinated people, are required to have a negative Covid-19 test result taken no more than three days before they board their flight.

What is my moral obligation to the places I visit where most people are not vaccinated?

The United States inoculation rollout has been among the fastest in the world, but there is a stark gap between its rapid rollout and the vaccination programs in different countries. Some nations have yet to report a single dose being administered.

Many countries are currently seeing a surge in new cases and are implementing strict coronavirus protocols, including mask mandates in public spaces, capacity limits at restaurants and tourist sites and other lockdown restrictions.

It is important to check coronavirus case rates, measures and medical infrastructure before traveling to your destination and not to let your guard down when you get there. Even though you are fully vaccinated, you may still be able to transmit the disease to local communities who have not yet been inoculated.

You can track coronavirus vaccination rollouts around the world here.

Frequently Asked Questions: Guidance for Travelers to Enter the U.S.

Updated Date: April 21, 2022

Since January 22, 2022, DHS has required non-U.S. individuals seeking to enter the United States via land ports of entry and ferry terminals at the U.S.-Mexico and U.S.-Canada borders to be fully vaccinated for COVID-19 and provide proof of vaccination upon request.  On April 21, 2022, DHS announced that it would extend these requirements. In determining whether and when to rescind this order, DHS anticipates that it will take account of whether the vaccination requirement for non-U.S. air travelers remains in place.

These requirements apply to non-U.S. individuals who are traveling for essential or non-essential reasons. They do not apply to U.S. citizens, Lawful Permanent Residents, or U.S. nationals.

Effective November 8, 2021, new air travel requirements applied to many noncitizens who are visiting the United States temporarily. These travelers are also required to show proof of COVID-19 vaccination. All air travelers, including U.S. persons, must test negative for COVID-19 prior to departure. Limited exceptions apply. See  CDC guidance  for more details regarding air travel requirements.

Below is more information about what to know before you go, and answers to Frequently Asked Questions about cross-border travel.

Entering the U.S. Through a Land Port of Entry or Ferry Terminal

Q. what are the requirements for travelers entering the united states through land poes.

A:  Before embarking on a trip to the United States, non-U.S. travelers should be prepared for the following:

• Possess proof of an approved COVID-19 vaccination as outlined on the  CDC  website.
• During border inspection, verbally attest to their COVID-19 vaccination status. 
• Bring a  Western Hemisphere Travel Initiative  compliant border crossing document, such as a valid passport (and visa if required), Trusted Traveler Program card, a Department of State-issued Border Crossing Card, Enhanced Driver’s License or Enhanced Tribal Card when entering the country. Travelers (including U.S. citizens) should be prepared to present the WHTI-compliant document and any other documents requested by the CBP officer.

 Q. What are the requirements to enter the United States for children under the age of 18 who can't be vaccinated?

A:  Children under 18 years of age are excepted from the vaccination requirement at land and ferry POEs.

Q: Which vaccines/combination of vaccines will be accepted?

A:  Per CDC guidelines, all Food and Drug Administration (FDA) approved and authorized vaccines, as well as all vaccines that have an Emergency Use Listing (EUL) from the World Health Organization (WHO), will be accepted.

Accepted Vaccines:

• More details are available in CDC guidance  here .
• 2 weeks (14 days) after your dose of an accepted single-dose COVID-19 vaccine;
• 2 weeks (14 days) after your second dose of an accepted 2-dose series;
• 2 weeks (14 days) after you received the full series of an accepted COVID-19 vaccine (not placebo) in a clinical trial;
• 2 weeks (14 days) after you received 2 doses of any “mix-and-match” combination of accepted COVID-19 vaccines administered at least 17 days apart.

Q. Is the United States requiring travelers to have a booster dose to be considered fully vaccinated for border entry purposes?

A:  No. The CDC guidance for “full vaccination” can be found here.

Q: Do U.S. citizens or lawful permanent residents need proof of vaccination to return to the United States via land POEs and ferry terminals?

A:  No. Vaccination requirements do not apply to U.S. citizens, U.S. nationals, or Lawful Permanent Residents (LPRs). Travelers that exhibit signs or symptoms of illness will be referred to CDC for additional medical evaluation.

Q: Is pre- or at-arrival COVID testing required to enter the United States via land POEs or ferry terminals?

A: No, there is no COVID testing requirement to enter the United States via land POE or ferry terminals. In this respect, the requirement for entering by a land POE or ferry terminal differs from arrival via air, where there is a requirement to have a negative test result before departure.

Processing Changes Announced on January 22, 2022 

Q: new changes were recently announced. what changed on january 22.

A:  Since January 22, 2022, non-citizens who are not U.S. nationals or Lawful Permanent Residents have been required to be vaccinated against COVID-19 to enter the United States at land ports of entry and ferry terminals, whether for essential or nonessential purposes. Previously, DHS required that non-U.S. persons be vaccinated against COVID-19 to enter the United States for nonessential purposes.  Effective January 22, all non-U.S. individuals, to include essential travelers, must be prepared to attest to vaccination status and present proof of vaccination to a CBP officer upon request. DHS announced an extension of this policy on April 21, 2022.

Q: Who is affected by the changes announced on January 22?

A: This requirement does not apply to U.S. citizens, U.S. nationals, or U.S. Lawful Permanent Residents. It applies to other noncitizens, such as a citizen of Mexico, Canada, or any other country seeking to enter the United States through a land port of entry or ferry terminal.

Q: Do U.S. citizens need proof of vaccination to return to the United States via land port of entry or ferry terminals?

A: Vaccination requirements do not apply to U.S. Citizens, U.S. nationals or U.S. Lawful Permanent Residents. Travelers that exhibit signs or symptoms of illness will be referred to CDC for additional medical evaluation. 

Q: What is essential travel?

A:  Under the prior policy, there was an exception from temporary travel restrictions for “essential travel.” Essential travel included travel to attend educational institutions, travel to work in the United States, travel for emergency response and public health purposes, and travel for lawful cross-border trade (e.g., commercial truckers). Under current policy, there is no exception for essential travel.

Q: Will there be any exemptions? 

A: While most non-U.S. individuals seeking to enter the United States will need to be vaccinated, there is a narrow list of exemptions consistent with the Centers for Disease Control and Prevention (CDC) Order in the air travel context.

• Certain categories of individuals on diplomatic or official foreign government travel as specified in the CDC Order
• Children under 18 years of age;
• Certain participants in certain COVID-19 vaccine trials as specified in the CDC Order;   
• Individuals with medical contraindications to receiving a COVID-19 vaccine as specified in the CDC Order;
• Individuals issued a humanitarian or emergency exception by the Secretary of Homeland Security;
• Individuals with valid nonimmigrant visas (excluding B-1 [business] or B-2 [tourism] visas) who are citizens of a country with limited COVID-19 vaccine availability, as specified in the CDC Order
• Members of the U.S. Armed Forces or their spouses or children (under 18 years of age) as specified in the CDC Order; and
• Individuals whose entry would be in the U.S. national interest, as determined by the Secretary of Homeland Security.

Q: What documentation will be required to show vaccination status?

A:  Non-U.S. individuals are required to be prepared to attest to vaccination status and present proof of vaccination to a CBP officer upon request regardless of the purpose of travel.

The current documentation requirement remains the same and is available on the CDC website . Documentation requirements for entry at land ports of entry and ferry terminals mirror those for entry by air.

Q: What happens if someone doesn’t have proof of vaccine status?

A: If non-U.S. individuals cannot present proof of vaccination upon request, they will not be admitted into the United States and will either be subject to removal or be allowed to withdraw their application for entry.

Q: Will incoming travelers be required to present COVID-19 test results?

A: There is no COVID-19 testing requirement for travelers at land border ports of entry, including ferry terminals.

Q: What does this mean for those who can't be vaccinated, either due to age or other health considerations? 

A: See CDC guidance for additional information on this topic. Note that the vaccine requirement does not apply to children under 18 years of age.

Q: Does this requirement apply to amateur and professional athletes?

A: Yes, unless they qualify for one of the narrow CDC exemptions.

Q: Are commercial truckers required to be vaccinated?

A: Yes, unless they qualify for one of the narrow CDC exemptions. These requirements also apply to bus drivers as well as rail and ferry operators.

Q. Do you expect border wait times to increase?

A:  As travelers navigate these new travel requirements, wait times may increase. Travelers should account for the possibility of longer than normal wait times and lines at U.S. land border crossings when planning their trip and are kindly encouraged to exercise patience.

To help reduce wait times and long lines, travelers can take advantage of innovative technology, such as facial biometrics and the CBP OneTM mobile application, which serves as a single portal for individuals to access CBP mobile applications and services.

Q: How is Customs and Border Protection staffing the ports of entry? 

A: CBP’s current staffing levels at ports of entry throughout the United States are commensurate with pre-pandemic levels. CBP has continued to hire and train new employees throughout the pandemic. CBP expects some travelers to be non-compliant with the proof of vaccination requirements, which may at times lead to an increase in border wait times. Although trade and travel facilitation remain a priority, we cannot compromise national security, which is our primary mission. CBP Office of Field Operations will continue to dedicate its finite resources to the processing of arriving traffic with emphasis on trade facilitation to ensure economic recovery.

Q: What happens if a vaccinated individual is traveling with an unvaccinated individual?  

A:  The unvaccinated individual (if 18 or over) would not be eligible for admission.

Q: If I am traveling for an essential reason but am not vaccinated can I still enter?

A:  No, if you are a non-U.S. individual. The policy announced on January 22, 2022 applies to both essential and non-essential travel by non-U.S. individual travelers. Since January 22, DHS has required that all inbound non-U.S. individuals crossing U.S. land or ferry POEs – whether for essential or non-essential reasons – be fully vaccinated for COVID-19 and provide related proof of vaccination upon request.

Q: Are sea crew members on vessels required to have a COVID vaccine to disembark?

A:  Sea crew members traveling pursuant to a C-1 or D nonimmigrant visa are not excepted from COVID-19 vaccine requirements at the land border. This is a difference from the international air transportation context.

Entering the U.S. via Air Travel

Q: what are the covid vaccination requirements for air passengers to the united states  .

A:  According to CDC requirements [www.cdc.gov/coronavirus/2019-ncov/travelers/noncitizens-US-air-travel.html | Link no longer valid], most noncitizens who are visiting the United States temporarily must be fully vaccinated prior to boarding a flight to the United States. These travelers are required to show proof of vaccination. A list of covered individuals is available on the CDC website.  

Q: What are the COVID testing requirements for air passengers to the United States?  

A:  Effective Sunday, June 12 at 12:01 a.m. ET, CDC will no longer require pre-departure COVID-19 testing for U.S.-bound air travelers.

COVID-19 is a nationally notifiable disease and reporting cases to CDC is supported by routine case notification through the National Notifiable Diseases Surveillance System (NNDSS), as well as resources provided through the CDC COVID-19 response. As of March 2022, CDC no longer recommends universal case investigation and contact tracing and recommends that health department jurisdictions prioritize specific settings and groups at increased risk. In addition, a decreasing number of case reports include information on pregnancy status. For these reasons CDC will stop reporting data on this page on July 19th, 2022. Information about findings from this data and about CDC’s ongoing data collection efforts to better understand the impact of COVID-19 during pregnancy can be found here .

In March 2022, CDC changed its data collection schedule to every 8 weeks for the nationwide COVID-19 infection-induced antibody seroprevalence (commercial laboratory) survey. It now includes information on antibodies for pediatric age groups (ages 6 months to 17 years). Adult antibody updates will be based on the national blood donor seroprevalence study .

This dashboard, which includes information for all age groups, has been updated through February 2022. Updated pediatric seroprevalence information from March 2022 is available here . CDC currently plans to end the nationwide SARS-CoV-2 antibody studies in December 2022.

Executive Order on Promoting COVID- ⁠ 19 Safety in Domestic and International   Travel

By the authority vested in me as President by the Constitution and the laws of the United States of America, it is hereby ordered as follows: 

Section 1.  Policy.  Science-based public health measures are critical to preventing the spread of coronavirus disease 2019 (COVID-19) by travelers within the United States and those who enter the country from abroad.  The Centers for Disease Control and Prevention (CDC), the Surgeon General, and the National Institutes of Health have concluded that mask-wearing, physical distancing, appropriate ventilation, and timely testing can mitigate the risk of travelers spreading COVID-19.  Accordingly, to save lives and allow all Americans, including the millions of people employed in the transportation industry, to travel and work safely, it is the policy of my Administration to implement these public health measures consistent with CDC guidelines on public modes of transportation and at ports of entry to the United States.   

Sec. 2.  Immediate Action to Require Mask-Wearing on Certain Domestic Modes of Transportation.

(a)  Mask Requirement.   The Secretary of Labor, the Secretary of Health and Human Services (HHS), the Secretary of Transportation (including through the Administrator of the Federal Aviation Administration (FAA)), the Secretary of Homeland Security (including through the Administrator of the Transportation Security Administration (TSA) and the Commandant of the United States Coast Guard), and the heads of any other executive departments and agencies (agencies) that have relevant regulatory authority (heads of agencies) shall immediately take action, to the extent appropriate and consistent with applicable law, to require masks to be worn in compliance with CDC guidelines in or on: 

(i)    airports; 

(ii)   commercial aircraft; 

(iii)  trains; 

(iv)   public maritime vessels, including ferries; 

(v)    intercity bus services; and

(vi)   all forms of public transportation as defined in section 5302 of title 49, United States Code.

(b)  Consultation.   In implementing this section, the heads of agencies shall consult, as appropriate, with interested parties, including State, local, Tribal, and territorial officials; industry and union representatives from the transportation sector; and consumer representatives.

(c)  Exceptions.   The heads of agencies may make categorical or case-by-case exceptions to policies developed under this section, consistent with applicable law, to the extent that doing so is necessary or required by law.  If the heads of agencies do make exceptions, they shall require alternative and appropriate safeguards, and shall document all exceptions in writing.

(d)  Preemption.  To the extent permitted by applicable law, the heads of agencies shall ensure that any action taken to implement this section does not preempt State, local, Tribal, and territorial laws or rules imposing public health measures that are more protective of public health than those required by the heads of agencies. 

(e)  Coordination.  The Coordinator of the COVID-19 Response and Counselor to the President (COVID-19 Response Coordinator) shall coordinate the implementation of this section.  The heads of agencies shall update the COVID-19 Response Coordinator on their progress in implementing this section, including any categorical exceptions established under subsection (c) of this section, within 7 days of the date of this order and regularly thereafter.  The heads of agencies are encouraged to bring to the attention of the COVID-19 Response Coordinator any questions regarding the scope or implementation of this section.

Sec. 3.  Action to Implement Additional Public Health Measures for Domestic Travel. 

(a)  Recommendations.   The Secretary of Transportation (including through the Administrator of the FAA) and the Secretary of Homeland Security (including through the Administrator of the TSA and the Commandant of the Coast Guard), in consultation with the Director of CDC, shall promptly provide to the COVID-19 Response Coordinator recommendations concerning how their respective agencies may impose additional public health measures for domestic travel.

(b)  Consultation.   In implementing this section, the Secretary of Transportation and the Secretary of Homeland Security shall engage with interested parties, including State, local, Tribal, and territorial officials; industry and union representatives from the transportation sector; and consumer representatives.  

Sec. 4.  Support for State, Local, Tribal, and Territorial Authorities.  The COVID-19 Response Coordinator, in coordination with the Secretary of Transportation and the heads of any other relevant agencies, shall promptly identify and inform agencies of options to incentivize, support, and encourage widespread mask-wearing and physical distancing on public modes of transportation, consistent with CDC guidelines and applicable law.

Sec. 5.  International Travel. 

(a)  Policy.   It is the policy of my Administration that, to the extent feasible, travelers seeking to enter the United States from a foreign country shall be: 

(i)   required to produce proof of a recent negative COVID-19 test prior to entry; and 

(ii)  required to comply with other applicable CDC guidelines concerning international travel, including recommended periods of self-quarantine or self-isolation after entry into the United States.

(b)  Air Travel.  

(i)    The Secretary of HHS, including through the Director of CDC, and in coordination with the Secretary of Transportation (including through the Administrator of the FAA) and the Secretary of Homeland Security (including through the Administrator of the TSA), shall, within 14 days of the date of this order, assess the CDC order of January 12, 2021, regarding the requirement of a negative COVID-19 test result for airline passengers traveling into the United States, in light of subsection (a) of this section.  Based on such assessment, the Secretary of HHS and the Secretary of Homeland Security shall take any further appropriate regulatory action, to the extent feasible and consistent with CDC guidelines and applicable law.  Such assessment and regulatory action shall include consideration of: 

(A)  the timing and types of COVID-19 tests that should satisfy the negative test requirement, including consideration of additional testing immediately prior to departure; (B)  the proof of test results that travelers should be required to provide; (C)  the feasibility of implementing alternative and sufficiently protective public health measures, such as testing, self-quarantine, and self-isolation on arrival, for travelers entering the United States from countries where COVID-19 tests are inaccessible, particularly where such inaccessibility of tests would affect the ability of United States citizens and lawful permanent residents to return to the United States; and (D)  measures to prevent fraud.

(ii)   The Secretary of HHS, in coordination with the Secretary of Transportation (including through the Administrator of the FAA) and the Secretary of Homeland Security (including through the Administrator of the TSA), shall promptly provide to the President, through the COVID-19 Response Coordinator, a plan for how the Secretary and other Federal Government actors could implement the policy stated in subsection (a) of this section with respect to CDC-recommended periods of self-quarantine or self-isolation after a flight to the United States from a foreign country, as he deems appropriate and consistent with applicable law.  The plan shall identify agencies’ tools and mechanisms to assist travelers in complying with such policy.

(iii)  The Secretary of State, in consultation with the Secretary of HHS (including through the Director of CDC), the Secretary of Transportation (including through the Administrator of the FAA), and the Secretary of Homeland Security, shall seek to consult with foreign governments, the World Health Organization, the International Civil Aviation Organization, the International Air Transport Association, and any other relevant stakeholders to establish guidelines for public health measures associated with safe international travel, including on aircraft and at ports of entry.  Any such guidelines should address quarantine, testing, COVID-19 vaccination, follow-up testing and symptom-monitoring, air filtration requirements, environmental decontamination standards, and contact tracing.  

(c)  Land Travel.  The Secretary of State, in consultation with the Secretary of HHS, the Secretary of Transportation, the Secretary of Homeland Security, and the Director of CDC, shall immediately commence diplomatic outreach to the governments of Canada and Mexico regarding public health protocols for land ports of entry.  Based on this diplomatic engagement, within 14 days of the date of this order, the Secretary of HHS (including through the Director of CDC), the Secretary of Transportation, and the Secretary of Homeland Security shall submit to the President a plan to implement appropriate public health measures at land ports of entry.  The plan should implement CDC guidelines, consistent with applicable law, and take into account the operational considerations relevant to the different populations who enter the United States by land.

(d)  Sea Travel.  The Secretary of Homeland Security, through the Commandant of the Coast Guard and in consultation with the Secretary of HHS and the Director of CDC, shall, within 14 days of the date of this order, submit to the President a plan to implement appropriate public health measures at sea ports.  The plan should implement CDC guidelines, consistent with applicable law, and take into account operational considerations.  

(e)  International Certificates of Vaccination or Prophylaxis.  Consistent with applicable law, the Secretary of State, the Secretary of HHS, and the Secretary of Homeland Security (including through the Administrator of the TSA), in coordination with any relevant international organizations, shall assess the feasibility of linking COVID-19 vaccination to International Certificates of Vaccination or Prophylaxis (ICVP) and producing electronic versions of ICVPs.  

(f)  Coordination.  The COVID-19 Response Coordinator, in consultation with the Assistant to the President for National Security Affairs and the Assistant to the President for Domestic Policy, shall coordinate the implementation of this section.  The Secretary of State, the Secretary of HHS, the Secretary of Transportation, and the Secretary of Homeland Security shall update the COVID-19 Response Coordinator on their progress in implementing this section within 7 days of the date of this order and regularly thereafter.  The heads of all agencies are encouraged to bring to the attention of the COVID-19 Response Coordinator any questions regarding the scope or implementation of this section.

Sec. 6.  General Provisions.   (a)  Nothing in this order shall be construed to impair or otherwise affect:

(i)   the authority granted by law to an executive department or agency, or the head thereof; or

(ii)  the functions of the Director of the Office of Management and Budget relating to budgetary, administrative, or legislative proposals.

(b)  This order shall be implemented consistent with applicable law and subject to the availability of appropriations.

CDC Updates COVID Travel Guidance for 120 Countries Ahead of Summer

Images By Tang Ming Tung / Getty Images

Key Takeaways

• The Centers for Disease Control and Prevention has updated its COVID travel guidance for more than a hundred countries.
• The CDC classifies travel to each country by level of COVID-19 risk.
• Infectious disease experts say it's relatively safe to travel internationally now, provided you're vaccinated and avoid high-risk countries.

The Centers for Disease Control and Prevention (CDC) has issued new COVID-19 travel guidelines for more than 120 countries.

The updated advice offers detailed information on specific countries for travelers who are vaccinated and for those who aren't. The CDC specifically assigns risk levels to each country based on the number of cases per 100,000 people.

To use the new guidance , travelers can search by the name of the country they’re interested in visiting and then learn whether its COVID-19 risk is very high, high, moderate, low, or unknown.

The CDC also offers detailed advice on what to do to stay safe in that particular country, broken down by whether you’re vaccinated or unvaccinated.

The new guidance arrives as COVID-19 cases dip to low levels previously seen at the start of the pandemic in March 2020.  As vaccination increases and cases drop, travel among Americans is picking up speed.

Just days after the CDC's updated guidance, the Transportation Security Administration (TSA) announced that it screened more than 2 million passengers on the same day for the first time since March 2020.

What the Risk Levels Mean

The CDC divides up countries based on four levels of risk.

Level 4: Very High Risk

Countries that are classified as very high-risk have more than 500 new cases per 100,000 people over the past 28 days. The CDC recommends against traveling to these countries, which currently include Brazil, India, and Iraq.

Level 3: High Risk

These countries have 100 to 500 cases per 100,000 residents. The CDC specifically recommends avoiding nonessential travel to these countries—including Mexico, Russia, and Iran—for people who are unvaccinated.

Level 2: Moderate Risk

Level 2 countries have 50 to 99 cases per 100,000, and currently include Finland, Cambodia, and Kenya. The CDC suggests that people who are unvaccinated and at increased risk of severe illness from COVID-19 avoid these countries.

Level 1: Low Risk

Level 1 countries are nations with less than 50 COVID-19 cases per 100,000 people, and include Australia, Israel, and Singapore. The agency still recommends that you get vaccinated before you travel to one of them.

What This Means For You

The CDC breaks down which countries are considered high and low risk for travel right now. If you decide to travel internationally, first check the risk level of the country you’re interested in visiting, and don’t forget to wear a mask on your journey.

Is International Travel Safe Right Now?

Infectious disease experts say your safety depends on your vaccination status. “For a fully vaccinated individual, international travel is low-risk,” infectious disease expert  Amesh A. Adalja, MD , senior scholar at the Johns Hopkins Center for Health Security, tells Verywell.

“If you’re fully vaccinated, I think international travel is OK,” Thomas Russo, MD , professor and chief of infectious disease at the University at Buffalo in New York, tells Verywell. “But one should be a little more cognizant of countries that have variants of concern, like India.”

While Russo says that “the consequences for fully vaccinated individuals might not be as bad” as they would be for those who aren't vaccinated, there is still a chance that they can bring the variants back home after traveling. “We’re trying to minimize importing those strains,” he says.

But there are “issues related to air travel in general,” Stanley Weiss, MD , professor of medicine at the Rutgers New Jersey Medical School, tells Verywell. “There is the issue of yourself and those near you, in screening areas, waiting areas, and on the plane."

Weiss points out that you can be exposed to COVID for long periods of time on international flights. And there's “a considerable period of time” where everyone may not always be masked.

Ultimately, “the decision to take an international trip currently is really a risk/benefit consideration that is dependent upon one's own risk tolerance,” Prathit Kulkarni, MD , assistant professor of medicine in infectious diseases at Baylor College of Medicine, tells Verywell.

He recommends being mindful of the risk level of the country you’re interested in visiting. “If it is possible to defer a trip to a country with very high transmission currently until transmission slows down a bit, that is likely preferred,” Kulkarni says.

It’s important to keep in mind that “you may not be able to get reasonable healthcare if you get sick” while visiting a higher risk area, John Sellick, DO , an infectious disease expert and professor of medicine at the University at Buffalo in New York, tells Verywell.

Adalja agrees. “Traveling to a very high-risk area, even when fully vaccinated, probably is not going to be a very fun trip if a country is spiraling out of control because of COVID-19 cases and hospitals in crisis,” he says.

How to Stay Safe When You Travel

“Sometimes there are extenuating circumstances necessitating travel; In this case, prevention steps are the best way to reduce risk,” Kulkarni says. That includes wearing a mask in the airport and on the plane and practicing good hand hygiene, Sellick adds.

Be aware, too, that you may have to get tested or quarantine—even if you’re fully vaccinated—because of regulations in place in other countries, Adalja says.

Weiss recommends bringing extra masks along for the trip and keeping a spare on you at all times. “You need enough with you to enable you to change them,” he says.

Overall, public health experts stress the importance of getting vaccinated before you travel. “It’s the most important thing you can do,” Russo says.

One Previous Dose

Two or More Previous Doses

At least 8 weeks after the last dose

4–8 weeks after the last dose

Recommendation for People Who May Get Additional Updated COVID-19 Vaccines

People who are moderately or severely immunocompromised  may get additional doses of updated COVID-19 vaccines. Talk to your healthcare provider about additional updated doses .

People who are immunocompromised and aged 65 years and older who received 1 dose of any updated 2023-2024 COVID-19 vaccine (Pfizer-BioNTech, Moderna or Novavax) should receive 1 additional dose of an updated 2023-2024 COVID-19 vaccine at least 2 months after the previous updated dose.

When Are You Up to Date?

People aged 5—64 years.

You are up to date when you get 1 updated COVID-19 vaccine . ‡

Children aged 6 months—4 years

You are up to date when you get all recommended doses, including at least 1 dose of updated COVID-19 vaccine.

People aged 65 years and older

You are up to date when you have received 2 updated 2023–2024 COVID-19 vaccine doses .*

People aged 65 and older who have not previously received any COVID-19 vaccine doses and choose to get Novavax should get 2 doses of updated Novavax vaccine, followed by 1 additional dose of any updated 2023–2024 COVID-19 vaccine to be up to date.

People who got the Johnson & Johnson/Janssen COVID-19 vaccine

You are up to date when you get 1 updated COVID-19 vaccine.

How Well COVID-19 Vaccines Work

• People who are up to date have lower risk of severe illness, hospitalization and death  from COVID-19 than people who are unvaccinated or who have not completed the doses recommended for them by CDC.
• Additional updated COVID-19 vaccine doses can help restore protection that has decreased since previous vaccination.
• CDC will continue to provide updates as we learn more.

About COVID-19 Vaccines

COVID-19 vaccines available in the United States are effective at protecting people from getting seriously ill, being hospitalized, and dying. As with other vaccine-preventable diseases, you are best protected from COVID-19 when you stay up to date with the recommended vaccinations.

COVID-19 vaccines recommended for use in the United States:

• Pfizer-BioNTech

COVID-19 Vaccines: 2023–2024 Updated, Bivalent, and Original

2023–2024 updated covid-19 vaccines.

As of October 3, 2023, the 2023-2024 updated Novavax vaccine was recommended by CDC for use in the United States.

As of September 12, 2023, the 2023–2024 updated Pfizer-BioNTech and Moderna COVID-19 vaccines were recommended by CDC for use in the United States.

The 2023–2024 updated COVID-19 vaccines more closely targets the XBB lineage of the Omicron variant  and could restore protection against severe COVID-19 that may have decreased over time. We anticipate the updated vaccines will be better at fighting currently circulating variants.

There is no preferential recommendation for the use of any one COVID-19 vaccine over another when more than one licensed or authorized, recommended, and age-appropriate vaccine is available.

2022–2023 Bivalent vaccines

As of September 11, 2023, the bivalent Pfizer-BioNTech and Moderna COVID-19 vaccines are no longer available for use in the United States.

The 2022–2023 bivalent vaccines were designed to protect against  both  the original virus that causes COVID-19  and  the Omicron variants BA.4 and BA.5. Two COVID-19 vaccine manufacturers, Pfizer-BioNTech and Moderna, had developed bivalent COVID-19 vaccines.

Original vaccines

As of April 18, 2023, the original Pfizer-BioNTech and Moderna COVID-19 vaccines are no longer available for use in the United States.

As of May 6, 2023, J&J/Janssen COVID-19 vaccine  is no longer available for use in the United States.

Previous COVID-19 vaccines were called “original” because they were designed to protect against the original virus that causes COVID-19.

Getting Vaccines If You Recently Had COVID-19

If you recently had COVID-19, you still need to stay up to date with your vaccines, but you may consider delaying your vaccine by 3 months.

Reinfection is less likely in the weeks to months after infection. However, certain factors could be reasons to get a vaccine sooner rather than later, such as:

• personal risk of severe disease,
• risk of disease in a loved one or close contact,
• local COVID-19 hospital admission level ,
• and the most common COVID-19 variant  currently causing illness.
• How can you prepare for vaccination?
• What can you expect during and after your vaccination?
• Uninsured? You can still get a free COVID-19 vaccine. Learn more about CDC’s Bridge Access program .

Learn actions you can take to stay healthy and safe on your trip. Vaccines cannot protect you from many diseases in Mexico, so your behaviors are important.

Eat and drink safely

Food and water standards around the world vary based on the destination. Standards may also differ within a country and risk may change depending on activity type (e.g., hiking versus business trip). You can learn more about safe food and drink choices when traveling by accessing the resources below.

• Choose Safe Food and Drinks When Traveling
• Water Treatment Options When Hiking, Camping or Traveling
• Global Water, Sanitation and Hygiene | Healthy Water
• Avoid Contaminated Water During Travel

You can also visit the Department of State Country Information Pages for additional information about food and water safety.

Prevent bug bites

Bugs (like mosquitoes, ticks, and fleas) can spread a number of diseases in Mexico. Many of these diseases cannot be prevented with a vaccine or medicine. You can reduce your risk by taking steps to prevent bug bites.

What can I do to prevent bug bites?

• Cover exposed skin by wearing long-sleeved shirts, long pants, and hats.
• Use an appropriate insect repellent (see below).
• Use permethrin-treated clothing and gear (such as boots, pants, socks, and tents). Do not use permethrin directly on skin.
• Stay and sleep in air-conditioned or screened rooms.
• Use a bed net if the area where you are sleeping is exposed to the outdoors.

What type of insect repellent should I use?

• FOR PROTECTION AGAINST TICKS AND MOSQUITOES: Use a repellent that contains 20% or more DEET for protection that lasts up to several hours.
• Picaridin (also known as KBR 3023, Bayrepel, and icaridin)
• Oil of lemon eucalyptus (OLE) or para-menthane-diol (PMD)
• 2-undecanone
• Always use insect repellent as directed.

What should I do if I am bitten by bugs?

• Avoid scratching bug bites, and apply hydrocortisone cream or calamine lotion to reduce the itching.
• Check your entire body for ticks after outdoor activity. Be sure to remove ticks properly.

What can I do to avoid bed bugs?

Although bed bugs do not carry disease, they are an annoyance. See our information page about avoiding bug bites for some easy tips to avoid them. For more information on bed bugs, see Bed Bugs .

For more detailed information on avoiding bug bites, see Avoid Bug Bites .

Some diseases in Mexico—such as dengue, Zika, leishmaniasis, and Chagas disease—are spread by bugs and cannot be prevented with a vaccine. Follow the insect avoidance measures described above to prevent these and other illnesses.

Stay safe outdoors

If your travel plans in Mexico include outdoor activities, take these steps to stay safe and healthy during your trip.

• Stay alert to changing weather conditions and adjust your plans if conditions become unsafe.
• Prepare for activities by wearing the right clothes and packing protective items, such as bug spray, sunscreen, and a basic first aid kit.
• Consider learning basic first aid and CPR before travel. Bring a travel health kit with items appropriate for your activities.
• If you are outside for many hours in heat, eat salty snacks and drink water to stay hydrated and replace salt lost through sweating.
• Protect yourself from UV radiation : use sunscreen with an SPF of at least 15, wear protective clothing, and seek shade during the hottest time of day (10 a.m.–4 p.m.).
• Be especially careful during summer months and at high elevation. Because sunlight reflects off snow, sand, and water, sun exposure may be increased during activities like skiing, swimming, and sailing.
• Very cold temperatures can be dangerous. Dress in layers and cover heads, hands, and feet properly if you are visiting a cold location.

Stay safe around water

• Swim only in designated swimming areas. Obey lifeguards and warning flags on beaches.
• Practice safe boating—follow all boating safety laws, do not drink alcohol if driving a boat, and always wear a life jacket.
• Do not dive into shallow water.
• Do not swim in freshwater in developing areas or where sanitation is poor.
• Avoid swallowing water when swimming. Untreated water can carry germs that make you sick.
• To prevent infections, wear shoes on beaches where there may be animal waste.

Leptospirosis, a bacterial infection that can be spread in fresh water, is found in Mexico. Avoid swimming in fresh, unchlorinated water, such as lakes, ponds, or rivers.

Keep away from animals

Most animals avoid people, but they may attack if they feel threatened, are protecting their young or territory, or if they are injured or ill. Animal bites and scratches can lead to serious diseases such as rabies.

Follow these tips to protect yourself:

• Do not touch or feed any animals you do not know.
• Do not allow animals to lick open wounds, and do not get animal saliva in your eyes or mouth.
• Avoid rodents and their urine and feces.
• Traveling pets should be supervised closely and not allowed to come in contact with local animals.
• If you wake in a room with a bat, seek medical care immediately. Bat bites may be hard to see.

All animals can pose a threat, but be extra careful around dogs, bats, monkeys, sea animals such as jellyfish, and snakes. If you are bitten or scratched by an animal, immediately:

• Wash the wound with soap and clean water.
• Go to a doctor right away.
• Tell your doctor about your injury when you get back to the United States.

Consider buying medical evacuation insurance. Rabies is a deadly disease that must be treated quickly, and treatment may not be available in some countries.

Reduce your exposure to germs

Follow these tips to avoid getting sick or spreading illness to others while traveling:

• Wash your hands often, especially before eating.
• If soap and water aren’t available, clean hands with hand sanitizer (containing at least 60% alcohol).
• Don’t touch your eyes, nose, or mouth. If you need to touch your face, make sure your hands are clean.
• Cover your mouth and nose with a tissue or your sleeve (not your hands) when coughing or sneezing.
• Try to avoid contact with people who are sick.
• If you are sick, stay home or in your hotel room, unless you need medical care.

Avoid sharing body fluids

Diseases can be spread through body fluids, such as saliva, blood, vomit, and semen.

Protect yourself:

• Use latex condoms correctly.
• Do not inject drugs.
• Limit alcohol consumption. People take more risks when intoxicated.
• Do not share needles or any devices that can break the skin. That includes needles for tattoos, piercings, and acupuncture.
• If you receive medical or dental care, make sure the equipment is disinfected or sanitized.

Know how to get medical care while traveling

Plan for how you will get health care during your trip, should the need arise:

• Carry a list of local doctors and hospitals at your destination.
• Review your health insurance plan to determine what medical services it would cover during your trip. Consider purchasing travel health and medical evacuation insurance.
• Carry a card that identifies, in the local language, your blood type, chronic conditions or serious allergies, and the generic names of any medications you take.
• Some prescription drugs may be illegal in other countries. Call Mexico’s embassy to verify that all of your prescription(s) are legal to bring with you.
• Bring all the medicines (including over-the-counter medicines) you think you might need during your trip, including extra in case of travel delays. Ask your doctor to help you get prescriptions filled early if you need to.

Many foreign hospitals and clinics are accredited by the Joint Commission International. A list of accredited facilities is available at their website ( www.jointcommissioninternational.org ).

In some countries, medicine (prescription and over-the-counter) may be substandard or counterfeit. Bring the medicines you will need from the United States to avoid having to buy them at your destination.

Malaria is a risk in some parts of Mexico. If you are going to a risk area, fill your malaria prescription before you leave, and take enough with you for the entire length of your trip. Follow your doctor’s instructions for taking the pills; some need to be started before you leave.

Select safe transportation

Motor vehicle crashes are the #1 killer of healthy US citizens in foreign countries.

In many places cars, buses, large trucks, rickshaws, bikes, people on foot, and even animals share the same lanes of traffic, increasing the risk for crashes.

Be smart when you are traveling on foot.

• Use sidewalks and marked crosswalks.
• Pay attention to the traffic around you, especially in crowded areas.
• Remember, people on foot do not always have the right of way in other countries.

Riding/Driving

Choose a safe vehicle.

• Choose official taxis or public transportation, such as trains and buses.
• Ride only in cars that have seatbelts.
• Avoid overcrowded, overloaded, top-heavy buses and minivans.
• Avoid riding on motorcycles or motorbikes, especially motorbike taxis. (Many crashes are caused by inexperienced motorbike drivers.)
• Choose newer vehicles—they may have more safety features, such as airbags, and be more reliable.
• Choose larger vehicles, which may provide more protection in crashes.

Think about the driver.

• Do not drive after drinking alcohol or ride with someone who has been drinking.
• Consider hiring a licensed, trained driver familiar with the area.
• Arrange payment before departing.

Follow basic safety tips.

• Wear a seatbelt at all times.
• Sit in the back seat of cars and taxis.
• When on motorbikes or bicycles, always wear a helmet. (Bring a helmet from home, if needed.)
• Avoid driving at night; street lighting in certain parts of Mexico may be poor.
• Do not use a cell phone or text while driving (illegal in many countries).
• Travel during daylight hours only, especially in rural areas.
• If you choose to drive a vehicle in Mexico, learn the local traffic laws and have the proper paperwork.
• Get any driving permits and insurance you may need. Get an International Driving Permit (IDP). Carry the IDP and a US-issued driver's license at all times.
• Check with your auto insurance policy's international coverage, and get more coverage if needed. Make sure you have liability insurance.
• Avoid using local, unscheduled aircraft.
• If possible, fly on larger planes (more than 30 seats); larger airplanes are more likely to have regular safety inspections.
• Try to schedule flights during daylight hours and in good weather.

Medical Evacuation Insurance

If you are seriously injured, emergency care may not be available or may not meet US standards. Trauma care centers are uncommon outside urban areas. Having medical evacuation insurance can be helpful for these reasons.

For information traffic safety and road conditions in Mexico, see Travel and Transportation on US Department of State's country-specific information for Mexico .

Maintain personal security

Use the same common sense traveling overseas that you would at home, and always stay alert and aware of your surroundings.

Before you leave

• Research your destination(s), including local laws, customs, and culture.
• Monitor travel advisories and alerts and read travel tips from the US Department of State.
• Enroll in the Smart Traveler Enrollment Program (STEP) .
• Leave a copy of your itinerary, contact information, credit cards, and passport with someone at home.
• Pack as light as possible, and leave at home any item you could not replace.

While at your destination(s)

• Carry contact information for the nearest US embassy or consulate .
• Carry a photocopy of your passport and entry stamp; leave the actual passport securely in your hotel.
• Follow all local laws and social customs.
• Do not wear expensive clothing or jewelry.
• Always keep hotel doors locked, and store valuables in secure areas.
• If possible, choose hotel rooms between the 2nd and 6th floors.

To call for emergency services while in Mexico, dial 066, 060, or 080. Write these numbers down to carry with you during your trip.

Learn as much as you can about Mexico before you travel there. A good place to start is the country-specific information on Mexico from the US Department of State.

Americans in Mexico have been arrested for purchasing souvenirs that were, or looked like, antiques and that local customs authorities believed were national treasures. Familiarize yourself with any local regulations for antiques and follow these tips:

• When you are considering purchasing an authentic antique or a reproduction, ask if you are allowed to export these items before you purchase them.
• If you buy a reproduction, document on the customs form that it is a reproduction.
• If you buy an authentic antique, obtain the necessary export permit (often from the national museum).

Healthy Travel Packing List

Use the Healthy Travel Packing List for Mexico for a list of health-related items to consider packing for your trip. Talk to your doctor about which items are most important for you.

Why does CDC recommend packing these health-related items?

It’s best to be prepared to prevent and treat common illnesses and injuries. Some supplies and medicines may be difficult to find at your destination, may have different names, or may have different ingredients than what you normally use.

If you are not feeling well after your trip, you may need to see a doctor. If you need help finding a travel medicine specialist, see Find a Clinic . Be sure to tell your doctor about your travel, including where you went and what you did on your trip. Also tell your doctor if you were bitten or scratched by an animal while traveling.

If your doctor prescribed antimalarial medicine for your trip, keep taking the rest of your pills after you return home. If you stop taking your medicine too soon, you could still get sick.

Malaria is always a serious disease and may be a deadly illness. If you become ill with a fever either while traveling in a malaria-risk area or after you return home (for up to 1 year), you should seek immediate medical attention and should tell the doctor about your travel history.

For more information on what to do if you are sick after your trip, see Getting Sick after Travel .

Here’s How Long the CDC Says to Isolate if You Test Positive for COVID in 2024

[table-of-contents] stripped

With over four years since the COVID-19 pandemic started, a lot has changed. For many, life has gone back to normal, treating the Coronavirus like the common cold. And while the virus continues to pop up (like the latest FLiRT COVID variants ), the Centers for Disease Control and Prevention (CDC) has changed its COVID-19 protocol recommendations for 2024, updating them to reflect the changing severity and transmission of the virus.

The updated guidance throws out the previous five-day isolation recommendation for a more relaxed approach. The CDC is also now lumping COVID-19 recommendations with those of the flu and RSV .

“CDC is making updates to the recommendations now because the U.S. is seeing far fewer hospitalizations and deaths associated with COVID-19 and because we have more tools than ever to combat flu, COVID, and RSV,” the organization said in a statement online.

The CDC also stressed the importance of “core prevention steps and strategies” to lower the risk of getting seriously ill from a respiratory virus, including staying up to date with vaccines, practicing good hand hygiene, and focusing on cleaner air by trying to bring in more fresh outside air, purifying indoor air (by using the best air purifiers ), and gathering outside instead of inside.

Meet the experts: William Schaffner, M.D., an infectious disease specialist and professor at the Vanderbilt University School of Medicine; and Amesh A. Adalja, M.D., senior scholar at the Johns Hopkins Center for Health Security

But many (understandably) want to know what they should now do when they get sick with COVID-19. Here’s what the CDC says, along with how infectious disease doctors feel about the changes.

What to do if you test positive for COVID-19

If you test positive for COVID-19 or have respiratory virus symptoms (like a fever, chills, fatigue, cough, runny nose, and/or headache) that aren’t explained by another cause, the CDC recommends that you stay home and away from others. During that isolation period, it's best to wear a high-quality, well-fitting mask, like an N95 mask, when you need to be around others.

The CDC says that you can go back to your normal activities when you’ve been fever-free without the use of fever-reducing medication, and feeling better for at least 24 hours.

When you go back to your normal activities, the CDC recommends that you “take added precaution” for the next five days, like using masks, practicing physical distancing, and testing yourself when you’ll be around other people indoors.

“Keep in mind that you may still be able to spread the virus that made you sick, even if you are feeling better,” the CDC says. “You are likely to be less contagious at this time, depending on factors like how long you were sick or how sick you were.”

If you develop a fever or start to feel worse after you’ve gone back to your normal activities, the CDC recommends that you stay home and away from others for at least 24 hours until your symptoms get better and you haven’t had a fever without the help of fever-reducing medication. Once you go back to your usual routine, the CDC recommends again taking extra precautions for the next five days.

If you’re at high risk for serious complications from COVID-19, are immunocompromised, or are over 65, it’s a good idea to contact your doctor to see if you may benefit from taking an antiviral medication like Paxlovid , says William Schaffner, M.D., an infectious disease specialist and professor at the Vanderbilt University School of Medicine.

What do experts think of the updated guidelines?

Infectious disease experts are supportive of the CDC’s change. “It’s a good thing and will be welcomed by the general public, which has largely been doing this on their own for some time,” Dr. Schaffner says. Dr. Schaffner says he and several other people in the infectious disease community have been urging the CDC to revise the guidelines for a while. “The CDC waited a bit to make sure that the current trends in COVID really were sustained,” he says.

Infectious disease expert Amesh A. Adalja, M.D., senior scholar at the Johns Hopkins Center for Health Security, says he’s “supportive” of the new guidelines. “They reflect the fact that the context of COVID-19—the respiratory virus infection for which we have the most tools—has changed,” he says. “Similar updates to the guidelines were made in California, Oregon, and many other countries and, in that respect, the CDC was lagging.”

Dr. Schaffner points out that, while people continue to get seriously ill and die from COVID-19, that’s no longer the case for most of the American public. “Well over 90% of the U.S. population has had some experience with COVID, through infection or vaccination, or both,” he says. “The virus itself is not as virulent or severe as it once was, and it appears to produce somewhat milder disease now."

Shortening the isolation period should have “no measurable impact” on how much COVID-19 spreads in the general population, Dr. Schaffner says.

How to protect people around you if you test positive

To protect others around you if you test positive for COVID-19, the CDC recommends isolating—including from members of your household—until you’ve been fever-free without the help of fever-reducing medications for 24 hours. “This is especially important if you’re around anyone who is at high risk of serious disease,” Dr. Schaffner says.

Masking up when you need to be around others and carefully washing your hands can also help limit the spread, the CDC notes. It’s also a good idea to take steps to create cleaner indoor air, like opening doors and windows and using exhaust fans, per the CDC . You can even try adding an air purifier to your space.

The updated COVID boosters help protect against serious infection, so getting vaccinated is one of your best lines of defense against serious illness. Dr. Schaffner stresses the importance of getting the COVID-19 vaccine when you’re healthy, as well. “So many people have not taken advantage of the updated vaccine,” he says. “But the vast majority of people being hospitalized today because of COVID are unvaccinated.”

International travelers to the US will be able to skip proof of COVID vaccine, WH says

The Biden administration will lift the COVID-19 vaccine requirement for inbound international air travelers on Friday.

"As we continue to monitor the evolving state of COVID-19 and the emergence of virus variants, we have the tools to detect and respond to the potential emergence of a variant of high consequence," President Joe Biden said in a proclamation Tuesday. "Considering the progress that we have made, and based on the latest guidance from our public health experts, I have determined that we no longer need the international air travel restrictions that I imposed in October 2021."

Biden announced the change last week , along with the end of vaccine requirements for federal employees and contractors, foreign nationals at the land border and others. The requirement for air travelers will lift at midnight Thursday as the coronavirus public health emergency ends. Biden previously  signed a bill ending the COVID national emergency  in April.

Is there still a vaccine requirement for international travelers coming to the US?

Not as of later this week.

Currently, all "non-U.S. citizen, non-U.S. immigrants traveling to the United States by air" must show proof of vaccination with limited exceptions, according to the Centers for Disease Control and Prevention's  website .

Industry group the U.S. Travel Association, which had called on the Biden administration to  end the vaccine requirement  for inbound international visitors and argued the rule was an impediment to tourism, applauded the change when it was announced last week.

“Today’s action to lift the vaccine requirement eases a significant entry barrier for many global travelers, moving our industry and country forward," Geoff Freeman, the organization's President and CEO, said in a statement last week. He also called on the federal government to "ensure U.S. airports and other ports of entry are appropriately staffed with Customs and Border Protection officers to meet the growing demand for entry."

The U.S.  lifted a requirement  that air travelers coming from China show proof of a negative COVID test in March. The policy took effect in January amid a surge of cases in China.

The U.S.  dropped its COVID testing rule  for international flyers in June.

The Department of Homeland Security also said in a news release that it will no longer require non-U.S. travelers coming into the country by land or at ferry terminals to be fully vaccinated or show proof of their vaccination status.

Do US travelers need to be vaccinated against COVID to travel internationally?

That depends. Many destinations have dropped their vaccination and testing requirements for travel, though some still have rules in place. The Philippines, for example, still requires travelers to be fully vaccinated or show proof of a negative COVID test in order to visit, according to the  U.S. Embassy in the Philippines .

The CDC also recommends travelers be up to date on their COVID vaccinations before leaving the country. The agency defines up to date as having one updated Pfizer-BioNTech or Moderna vaccine for people age 6 and up, which "protect against both the original virus that causes COVID-19 and the Omicron variant BA.4 and BA.5," according to its  website .

There’s a new highly transmissible COVID-19 variant. Could FLiRT lead to a summer uptick?

Two new COVID-19 subvariants, collectively nicknamed FLiRT, are increasingly edging out the winter’s dominant strain ahead of a possible summer uptick in coronavirus infections.

The new FLiRT subvariants, officially known as KP.2 and KP.1.1, are believed to be roughly 20% more transmissible than their parent, JN.1 , the winter’s dominant subvariant, said Dr. Peter Chin-Hong, an infectious-disease expert at UC San Francisco.

The two FLiRT subvariants combined comprised an estimated 35% of coronavirus infections nationally for the two-week period that began April 28, according to the U.S. Centers for Disease Control and Prevention. By contrast, JN.1 is now believed to comprise 16% of infections; in mid-winter, it was blamed for more than 80%.

“It’s been quite a while since we’ve had a new dominant variant in the U.S.,” said Dr. David Bronstein, an infectious diseases specialist at Kaiser Permanente Southern California. “With each of these variants that takes over from the one before it, we do see increased transmissibility — it’s easier to spread from person to person. So, that’s really the concern with FLiRT.”

The largest FLiRT subvariant, KP.2, is growing particularly fast as a proportion of coronavirus infections. In late March, it made up just 4% of estimated infections nationally; most recently, it’s estimated to make up 28.2%.

Americans want to forget about COVID-19, but fallout from the pandemic is shaping voter attitudes about the nation’s economy and divisive politics heading into a Biden-Trump rematch.

The new subvariants have been dubbed FLiRT for the mutations on the evolved COVID-19 virus. “So instead of an ‘L,’ there’s an ‘F.’ And instead of a ‘T,’ there’s an ‘R.’ And then they put an ‘i’ in to make it cute,” Chin-Hong said.

Despite their increased transmissibility, the new mutations don’t appear to result in more severe disease. And the vaccine is expected to continue working well, given the new subvariants are only slightly different from the winter version.

The entry of the subvariants also come as COVID-19 hospitalizations hit record lows. For the week ending April 27, there were 5,098 admissions — one-seventh of this winter’s peak, in which 35,137 admissions were reported for the week that ended Jan. 6.

However, as of May 1, hospitals nationwide are no longer required to report COVID-19 admissions to the U.S. Department of Health and Human Services; only voluntarily submitted data will now be posted nationally.

In Los Angeles County, COVID-19 levels appear to be in a lull. For the week that ended April 27, coronavirus levels in L.A. County wastewater were at 8% of the winter peak.

Still, some doctors say they wouldn’t be surprised if there is a summer uptick in COVID cases — as has occurred in prior seasons.

“By the summer, we can expect people’s immunity to be a little bit lower,” Chin-Hong said. For those who are older or immunocompromised, “they are potentially at risk for getting more serious disease.”

Plus, people often gather indoors during summer to avoid the heat, which can increase the risk of transmission in crowded public venues.

Chin-Hong said he is seeing COVID-19 patients at UC San Francisco with serious illness, and “they were either very old or very immune compromised and they didn’t get the most recent shots.”

That the FLiRT subvariants are more easily able to spread underscores how important it is for those most at risk to be up to date on vaccinations and stay away from those who are sick, doctors say.

And while the chance of long COVID is likely less than the early days of the pandemic, it still exists.

Many people haven’t gotten a recent COVID-19 vaccination, data show. For the week that ended Feb. 24, 29% of seniors nationwide had received a dose of the updated vaccine that became available in September . In California, as of April 30, about 36% of seniors had received an updated dose.

The U.S. Centers for Disease Control and Prevention recommend that seniors 65 and older get a second dose of the 2023-24 COVID-19 vaccination.

“We are still seeing those hospitalizations and bad outcomes, and even folks who are passing away from COVID. It hasn’t gone away,” Bronstein said. “The good news is that the ... vaccine still is very good at protecting you against hospitalizations, severe outcomes and death.”

Between October and April, more than 42,000 COVID-19 deaths were recorded nationally, according to the CDC. That’s significantly larger than the estimated flu deaths over the same time: 24,000.

Still, the number is smaller than the comparable period for the prior season, when more than 70,000 COVID deaths were reported. And that tally is far smaller than the first two devastating pandemic winters: Between October 2021 and April 2022, more than 272,000 deaths were recorded; and between October 2020 and April 2021, the number was more than 370,000.

The CDC in February recommended that seniors 65 and older get a second dose of the updated vaccine as long as it had been at least four months since an earlier injection. The CDC also says everyone 6 months and older should get a dose of the updated vaccine.

“Right now, the most important thing that folks can do is get the vaccine,” Bronstein said. He suggested those who are especially vulnerable continue to mask whenever possible, especially in places like crowded airports and planes.

In addition, he said, it’s important that people who are sick stay at home to avoid spreading germs to others, particularly the elderly. And if sickened people must leave home, they should wear a mask around others.

“Even in the summertime, what may feel like a cold can actually be a COVID infection,” Bronstein said. “We need to make sure that if you’re sick, that we’re testing whenever possible, staying home ... and make sure that your symptoms are more mild before you decide to go back to your regular activities.”

U.S. health officials drop 5-day isolation time for COVID-19

The CDC said people who test positive for COVID-19 no longer need to stay in isolation for five days and can return to regular activities if their symptoms are mild and improving and it’s been a day since they’ve had a fever.

March 1, 2024

California recommends that people with COVID-19 symptoms stay home until symptoms are mild and improving and they haven’t had a fever for 24 hours without medication.

They should also mask around others while indoors for 10 days after becoming sick or, if they have no symptoms, after testing positive. They can stop wearing a mask sooner, if they have two consecutive negative rapid test results at least a day apart. But they should avoid contact with all higher-risk people for 10 days, according to the state Department of Public Health.

And ahead of travel plans this summer, Chin-Hong suggested that older people speak with their healthcare provider about making sure that, should they come down with COVID-19, that Paxlovid can be prescribed without interfering with other medications. Paxlovid is an antiviral drug that, when taken by people at risk for severe COVID-19 who have mild-to-moderate illness, reduces the risk of hospitalization and death.

Chin-Hong also suggests that it makes sense for healthcare providers to prescribe Paxlovid to higher-risk people planning to travel where the medicine may not be readily available, as a “just-in-case” prescription. Clinicians have that discretion since Paxlovid has been fully approved by the U.S. Food and Drug Administration, which gives healthcare providers greater leeway in deciding when to prescribe the drug.

Earlier this year, another medicine was also made available to help protect the most vulnerable people — such as cancer patients and those who have received organ transplants. It’s a monoclonal antibody called Pemgarda , which is administered intravenously and can be given once every three months. Authorized by the FDA for emergency use, it’s given prophylactically and can help recipients prevent COVID-19 if they are later exposed to an infected person.

Anticipation is also building for a fresh version of the COVID-19 vaccine to be released possibly by September. It could be designed against last winter’s JN.1 strain, but it’s also possible officials decide it should be designed against the rising FLiRT subvariants, Chin-Hong said.
