Crime, civil unrest and terrorism are common risk factors for countries that end up on the State Department's "Do Not Travel" advisory list.

In 2024, tourism across the globe is “well on track” to return to pre-pandemic levels, according to projections by UN Tourism.

Global conflicts and natural disasters , ranging from a series of coups across Africa to catastrophic earthquakes in the Middle East affected international travel patterns throughout 2023. Still, international tourist arrivals reached 87% of pre-pandemic levels in 2023, according to estimates by UN Tourism .

In January 2024 alone, about 4.6 million U.S. citizens left the country for international destinations, 17% higher than the same month in 2019, according to the International Trade Administration . But some destinations warrant more caution than others.

On Oct. 19, 2023, following the outbreak of war between Israel and Gaza and flaring tensions in the region, the U.S. State Department issued a worldwide caution advisory due to “increased tensions in various locations around the world, the potential for terrorist attacks, demonstrations or violent actions against U.S. citizens and interests.” Prior to this update, the most recent worldwide caution advisory was issued in 2022 after a U.S. strike killed Ayman al-Zawahiri, Osama bin Laden’s successor as leader of Al Qaeda, causing “a higher potential for anti-American violence.” The worldwide caution advisory remains in effect.

The U.S. State Department also issues individual travel advisory levels for more than 200 countries globally, continually updating them based on a variety of risk indicators such as health, terrorism and civil unrest. Travel advisory levels range from Level 1, which means exercise normal precautions, to Level 4, which means do not travel there.

About 10% of countries – 19 total – have a Level 4: “Do Not Travel” advisory as of Mar. 4. In Level 4 countries, the U.S. government may have “very limited ability” to step in should travelers’ safety or security be at risk, according to the State Department. Crime, civil unrest, kidnapping and terrorism are common risk factors associated with Level 4 countries.

So far in 2024, the State Department made changes to the existing Level 4 advisories for Myanmar, Iran and Gaza, and moved Niger and Lebanon off of the Level 4 list.

Places With a Level 4 Travel Advisory

These are the primary areas the U.S. government says not to travel to right now, in alphabetical order:

Jump to Place: Afghanistan Belarus Burkina Faso Central African Republic Myanmar (formerly Burma) Gaza Haiti Iran Iraq Libya Mali Mexico North Korea (Democratic People's Republic of Korea) Russia Somalia South Sudan Sudan Syria Ukraine Venezuela Yemen

Afghanistan: The Central Asian country is wrestling with “terrorism, risk of wrongful detention, kidnapping and crime,” according to the State Department. U.S. citizens are specifically at risk for wrongful detention and kidnapping. In 2022, the government reinstituted public floggings and executions, and women’s rights are disappearing under Taliban control. The U.S. Embassy in Kabul halted operations in August 2021. Since the Taliban took control , many forms of international aid have been halted . Meanwhile, in 2023, some of the year’s deadliest earthquakes killed more than 2,400 in Afghanistan while the country continues to face a years-long extreme drought.

Belarus: Belarus, which shares a western border with Russia and a southern border with Ukraine, has been flagged for “Belarusian authorities’ continued facilitation of Russia’s war against Ukraine, the buildup of Russian military forces in Belarus, the arbitrary enforcement of local laws, the potential of civil unrest, the risk of detention, and the Embassy’s limited ability to assist U.S. citizens residing in or traveling to Belarus.” The U.S. Embassy in Minsk halted operations in February 2022.

Burkina Faso: Terrorism, crime and kidnapping are plaguing this West African nation. Terrorist attacks may target hotels, restaurants and schools with little to no warning, and the East and Sahel regions of the country are under a state of emergency. In late November 2023, hundreds died in clashes between state security forces and rebels near the country’s border with Mali. In June, more than 2 million people in Burkina Faso were displaced due to “violence linked to al-Qaida and the Islamic State group.”

Central African Republic: While there have not been specific incidents of U.S. citizens targeted with violence or crime, violent crime and sudden closure of roads and borders is common. The advisory states that “Embassy Bangui’s limited capacity to provide support to U.S. citizens, crime, civil unrest, and kidnapping” is a factor in its assessment. Recent data from UNICEF suggests the country has the worst drinking water accessibility of all countries in 2022.

Myanmar (Formerly Burma): Armed conflict and civil unrest are the primary reasons to not travel to this Southeast Asian country, which experienced a military coup in early 2021. Limited health care resources, wrongful detentions and “areas with land mines and unexploded ordnance” are also listed as risk factors. After Ukraine and Israel, Myanmar had the highest conflict-related death toll in 2023.

Gaza : Hamas, a foreign terrorist organization as designated by the State Department, controls much of the Gaza Strip, which shares borders with both Israel and Egypt. On Oct. 7, 2023, Hamas fighters broke across the border into Israel, killing hundreds of civilians and soldiers in a brazen attack that stunned Israelis. On Oct. 10, Israel hit the Gaza Strip with “the fiercest air strikes in its 75-year conflict” according to Reuters . The conflict has since escalated into war between Israel and Hamas, with regular Israeli airstrikes leading to extensive civilian casualties in Gaza. As of mid-December, nearly 85% of Gaza’s population were displaced from their homes, according to UN estimates . The region continues to face shortages of food , water, electricity and medical supplies , with conditions deemed “far beyond a humanitarian crisis.” The State Department warns of terrorism and armed conflict within Gaza’s borders.

Haiti: In July 2023, the Department of State ordered all non-emergency U.S. government personnel and family members to leave the U.S. Embassy in Port-au-Prince in response to the increased risk of kidnapping and violent crime in the country , as well as armed conflict between gangs and police. The travel advisory states that cases of kidnapping “often involve ransom negotiations and U.S. citizen victims have been physically harmed during kidnappings.” The travel advisory also states that “U.S. citizens in Haiti should depart Haiti as soon as possible” given “the current security situation and infrastructure challenges.” A series of gang attacks in late September 2023 caused thousands to flee their homes, and many aid groups have been forced to cut or suspend operations amid escalating violence in recent months.

Iran: Terrorism, kidnapping and civil unrest are risk factors for all travelers to Iran, while U.S. citizens are specifically at risk for “arbitrary arrest.” U.S.-Iranian nationals such as students, journalists and business travelers have been arrested on charges of espionage and threatening national security. Executions in Iran rose sharply between 2021 and 2022, bringing the country’s total to nearly 580 people over the year, according to a report by Amnesty International released in May 2023.

Iraq: The State Department cites “terrorism, kidnapping, armed conflict [and] civil unrest” as cause for the country’s Level 4 distinction. Iraq’s northern borders, and its border with Syria, are especially dangerous. Since the escalation of conflict in neighboring Israel in October, there has been an increase in attacks against Iraqi military bases, which host U.S. troops and other international forces. In October 2023, non-emergency U.S. government personnel and eligible family members were ordered to leave the U.S. embassy in Baghdad.

Libya: Following the end of its dictatorship over a decade ago, Libya has been wrought with internal conflict between armed groups in the East and West. Armed conflict, civil unrest, crime, kidnapping and terrorism are all risk factors. U.S. citizens have been targets of kidnapping for ransom, with terrorists targeting hotels and airports frequented by Westerners. The U.S. Embassy in Tripoli halted operations in 2014. In mid-September 2023, floods, which some say were intensified by climate change , killed thousands in eastern Libya. Clashes between armed factions escalated across the country in the latter half of 2023, including in the capital city of Tripoli and in Benghazi.

Mali: After experiencing military coups in 2020 and 2021, crime, terrorism and kidnapping are all prevalent threats in this West African landlocked nation. In July 2022, non-emergency U.S. government employees and their families were ordered to leave the country due to higher risk of terrorist activity. A U.N. report in August 2023 said that military groups in the country, including both Mali security forces and possibly Russian Wagner mercenaries, were spreading terror through the use of violence against women and human rights abuses. Democratic elections were supposed to occur in February 2024, but Mali’s military junta postponed the plans indefinitely. In December, the U.N. officially ended a decade-long peacekeeping presence in the country, which had been among the agency’s deadliest missions, with hundreds of the mission personnel killed since 2013.

Mexico: Each state in Mexico is assessed separately for travel advisory levels. Six of the 32 states in Mexico are designated as Level 4: Colima, Guerrero, Michoacan, Sinaloa, Tamaulipas and Zacatecas. Crime and kidnapping are listed as the primary risk factors throughout the country. Nearly 112,000 people were missing across the country as of October, a number the U.N. has called “alarming.”

North Korea (Democratic People’s Republic of Korea): U.S. passports are not valid for travel “to, in, or through” this country, home to one of the world's longest-running dynastic dictatorships. The travel advisory states that the Level 4 distinction is due to “the continuing serious risk of arrest and long-term detention of U.S. nationals.” In July 2023, a U.S. soldier fled across the border into North Korea, where he is believed to be in North Korean custody, the first American detained in the North in nearly five years. He was returned to U.S. custody in September 2023.

Russia: The travel advisory for Russia cites its invasion of Ukraine , harassment of U.S. citizens by Russian government officials and arbitrary law enforcement as a few of the reasons for the Level 4 designation. Chechnya and Mount Elbrus are specifically listed as Level 4 regions. Terrorism, civil unrest, health, kidnapping and wrongful detention are all noted as risks.

Russia Invades Ukraine: A Timeline

Somalia: A severe drought resulting from five failed rainy seasons in a row killed 43,000 people in 2022, and caused a famine amid conflict with Islamist insurgents . Violent crime is common throughout Somalia , pirates frequent its coast off the Horn of Africa, and medical facilities, where they exist, have limited capacity. Crime, terrorism, civil unrest, health and kidnapping are all risk factors. In January 2024, some passengers aboard a U.N.-contracted helicopter were taken hostage by al-Shabaab militants after the vehicle crashed in central Somalia.

South Sudan: Crime, kidnapping and armed conflict are the primary risk factors for South Sudan, which separated from Sudan in 2011, making it the world’s newest country . Weapons are readily available, and travelers have been victims of sexual assault and armed robbery.

Sudan: The U.S. evacuated its embassy in Khartoum in April 2023, and the country closed its airspace due to the ongoing conflict in the country, only permitting humanitarian aid and evacuation efforts. Fighting has escalated in the region between two warring generals seeking to gain control after a military coup in 2021 ousted the country’s prime minister. Civil unrest is the primary risk factor for Africa’s third largest country by area. Crime, terrorism, kidnapping and armed conflict are also noted. The International Criminal Court began investigating alleged war crimes and violence against African ethnic groups in the country in 2023. Millions have fled their homes due to conflict, and the U.N. has said its efforts to provide aid have been hindered by a lack of support, safety and resources. As recently as December 2023, the United Nations warned of catastrophic famine , with millions of children at-risk for malnutrition .

Syria: The advisory states that “No part of Syria is safe from violence,” with terrorism, civil unrest, kidnapping, armed conflict and risk of unjust detention all potential risk factors. U.S. citizens are often a target for kidnappings and detention. The U.S. Embassy in Damascus halted operations in 2012. Fighting in neighboring Israel has escalated since October, and the conflict has spilled over into Syria, where the U.S. has carried out air strikes following drone and rocket attacks against American troops in Syria and Iraq, triggered by the Israel-Hamas war.

Ukraine: Russian setbacks in their invasion of Ukraine buoyed hopes in Ukraine in 2023. However, Ukraine is a Level 4 country due to Russia’s invasion, with crime and civil unrest also noted as risk factors. The country’s forces shot down two Russian fighter jets on Christmas Eve 2023, in a move Ukrainian President Volodymyr Zelenskyy said “sets the right mood for the entire year ahead.”

Venezuela: Human rights abuses and lack of health care plague this South American nation, which has been in a political crisis since 2014. In 2019, diplomatic personnel were withdrawn from the U.S. Embassy in Caracas. Threats in the country include crime, civil unrest, kidnapping, wrongful detention and poor health infrastructure.

Yemen: Six of the nine risk factors defined by the State Department – terrorism, civil unrest, health risks, kidnapping, armed conflict and landmines – are all present in Yemen. Despite private companies offering tourist visits to the Yemeni island of Socotra, the U.S. government argues those arranging such visits “are putting tourists in danger.” Civil war and cholera are also both present throughout the country. The U.S. Embassy in Sanaa halted operations in 2015. The country has experienced a relative lull in the civil war fighting, but as peace negotiations have gotten traction, flare ups in the fighting have jeopardized progress. Most recently, the U.S. and U.K. have carried out a series of airstrikes in the country, targeting Iran-backed Houthi sites.

Other Countries to Watch

Since Jan. 1, the State Department has updated travel advisories for 17 different countries as well as for the West Bank and Gaza, adding information about specific regions or risk factors, or simply renewing an existing advisory. Travel advisory levels can change based on several factors in a nation, such as increased civil unrest, policies that affect human rights or higher risks of unlawful detention.

The State Department has given about 25 countries an assessment of Level 3, meaning it recommends people “reconsider travel” to those destinations.

On Oct. 14, one week after the deadly Hamas attack on Israel, Israel and the West Bank were both moved from Level 2 to Level 3, while Gaza remains at Level 4. The region’s travel advisory was updated in November to reflect travel restrictions for certain government employees who have not already left the area, and it was updated again on Jan. 3.

Following the outbreak of the Israel-Hamas war in early October, the U.S. State Department raised Lebanon ’s travel advisory level from a Level 3 to a Level 4 level due to “the unpredictable security situation related to rocket, missile, and artillery exchanges” between Israel and Hezbollah or other militant groups. In December, the U.S. Embassy in Beirut returned to normal staffing and presence, and on Jan. 29, the country was moved back to Level 3. Crime, terrorism, armed conflict, civil unrest, kidnapping and unexploded landmines are listed as the country’s primary risk factors. However, the country’s borders with Syria and with Israel, as well as refugee settlements within Lebanon, are specifically noted as Level 4 regions.

China became a Level 3 country in late 2020, with an update in December 2022 citing “the surge in COVID-19 cases, arbitrary enforcement of local laws, and COVID-19-related restrictions” as the reason for the advisory. In June 2023, the Hong Kong Special Administrative Region (SAR) was moved from the Level 3 to the Level 2 list, but travelers are still advised to be cautious in the area due to “arbitrary enforcement of local laws.” Meanwhile, Macau remains at Level 3.

Following an attempted coup in August 2023, Niger was elevated to Level 4 in August and the Department of State ordered all non-emergency U.S. government personnel and family members to leave the U.S. Embassy in Niamey. In early January 2024, the overall risk level for the country was lowered back to Level 3. Despite the new classification, the State Department still asks non-emergency government personnel and eligible family members to depart the country.

In mid-December 2023 there was an explosion at Guinea’s main fuel depot which has since affected access to health care and basic goods and services. The country was subsequently designated a Level 3 nation after having previously been Level 2. Concerns about civil unrest, health, crime and fuel shortages impacting local infrastructure were listed as the primary risk factors contributing to the change.

Several Level 3 countries are among the worst countries for human trafficking, as designated by the State Department’s annual Trafficking in Persons Report . Level 3 countries on this list include Papua New Guinea, Guinea Bissau, China and Chad. There are also nine Level 4 countries designated as among the worst for human trafficking: Afghanistan, Belarus, Iran, Myanmar, North Korea, Russia, Syria, South Sudan and Venezuela.

Over 70 countries are currently at Level 2, meaning the State Department recommends travelers “exercise increased caution” when traveling to those destinations.

Botswana became the newest Level 2 country on Feb. 26 after having previously been Level 1, with crime noted as the primary risk factor.

France, which saw nationwide protests throughout 2023, has civil unrest and terrorism noted as risk factors for its Level 2 status, and Sweden’s Level 2 status is associated with risks of terrorism.

The Level 2 travel advisory for the Bahamas was updated in January to reflect water safety concerns. The advisory warns that “activities involving commercial recreational watercraft, including water tours, are not consistently regulated” and notes that government personnel are “not permitted to use independently operated jet-ski rentals on New Providence and Paradise Islands.” It also warns visitors to be mindful of sharks, weather and water conditions. The advisory also says that crime is a primary risk factor with gang-on-gang violence contributing to high homicide rates in some areas. Visitors are asked to “be vigilant” and to not physically resist robbery attempts.

Bangladesh 's Level 2 travel advisory was updated in October 2023 to add a note about the country’s general election , which took place Jan. 7, 2024. The advisory states “demonstrations intended to be peaceful can turn confrontational and escalate into violence.” The U.S. has since claimed the country’s election was not free nor fair.

In November 2023, several Level 2 travel advisories were updated with new cautionary information. The advisory for Ghana was updated to reflect threats against LGBTQI+ travelers specifically, noting “anti-LGBTQI+ rhetoric and violence have increased in recent years.” Meanwhile, the advisory for South Africa was updated in February to note that routes recommended by GPS may be unsafe with higher risk for crime.

Turkmenistan was moved off of the Level 2 list to become the newest addition to the Level 1 list on Jan. 22, meaning normal precautions are recommended but there are no risk factors causing travelers to practice increased caution.

The State Department asks travelers to pay attention to travel advisory levels and alerts , review country information pages for their destinations and read related country security reports before going abroad.

Is it safe to go there? The U.S. travel advisory system, explained

If you’re planning an international trip, here’s how to use the State Department’s country-by-country guide to minimize your risk of encountering crime, violence, or civil unrest.

On October 19, the U.S. Department of State issued a rare advisory that Americans overseas “exercise increased caution” due to heightened tensions and chances of terrorism around the world, spurred by the Israel-Hamas war. It’s part of a system of travel warnings that’s been around in some form since 1978, designed to help citizens assess how safe a destination might be at a given time.

The current version of the system, which launched in 2018, gives fluid rankings from Level 1 (exercise normal precautions) to Level 4 (do not travel), indicating how risky countries (and in some cases, regions) are for Americans to visit. Rankings are based on factors such as crime rates, civil unrest, and the threat of terrorism. They are meant to give “clear, timely, and reliable information about every country in the world so they can make informed travel decisions,” says a State Department spokesperson.  

Not surprisingly, on October 14, the State Department moved Israel and the West Bank to Level 3 (reconsider travel) and Gaza to Level 4.  

Here’s how the advisories work and how to use them.

What is a travel advisory?

The U.S. State Department inaugurated the travel advisory system in 1978, initially aiming warnings at airlines and travel companies. The system was scrutinized after the 1988 bombing of a Pan Am flight from London to New York , which exploded over Lockerbie, Scotland , killing all 259 passengers and crew plus 11 people on the ground.  

Investigations found U.S. authorities had been aware of a credible threat to a Pan Am flight but hadn’t informed the public. In response, the media and consular offices began issuing travel warnings. In 2018 the U.S. introduced its current four-tier advisory system. There are near-identical versions in Canada , Australia , and New Zealand .

To determine rankings, the State Department considers a nation’s political volatility, crime trends, medical care standards, and the threat of kidnappings or terrorism. (Politics also ends up playing an unspoken role.) Some countries, such as Russia , receive a Level 4 ranking partly because the U.S. government may have limited ability to assist citizens there. Others rise to Level 4 due to a crisis, such as the military coup that recently rocked Niger .  

When the travel advisory system relaunched in 2018, it also included state-by-state evaluations for Mexico , which draws more than 11 million American travelers a year. “Some Mexican states are quite safe for U.S. tourists, while others are riskier due to narco-trafficking violence,” says Ryan Larsen , executive director of the Institute for Global Engagement at Western Washington University. Yucatán and Campeche states are currently at Level 1, while six other Mexican states are at Level 4, including Sinaloa.

Epidemics and natural disasters also can prompt a travel advisory number to rise. Americans may be prompted to reconsider visiting a country recovering from a tsunami or major wildfires, since their presence could hinder rehabilitation efforts. This occurred after the February 2023 earthquakes in Turkey . Such advisories can remain in place for weeks or months.

The strictest-ever advisories came in April 2021, amid the COVID-19 pandemic , says Larsen, who did a thesis   on U.S. travel warnings. At that time, about 80 percent of the world’s countries were at Level 4.

At press time, about 70 percent of the world’s countries were rated Level 1 or Level 2 by the State Department, indicating they’re relatively safe. There are currently 21 countries at Level 3 and 21 at Level 4.

How to use travel advisories

Before booking an international trip, consult the State Department website to see where your destination ranks. While Level 1 and 2 countries are considered relatively safe, you should still register with the U.S. Smart Traveler Enrollment Program (STEP) . This lets Americans overseas use their smartphone to receive travel advisory updates and alerts about emerging dangers in their destination (protests, extreme weather).

Level 3 countries are considered more dangerous for foreign visitors, who should “reconsider travel,” according to the State Department. If you are headed to a Level 3 country, which currently includes Pakistan and Colombia , do wider research on its safety and on the places you’ll visit there, advises Jun Wen , a professor of tourism at Australia’s Edith Cowan University. For instance, while some remote areas in the Colombian Amazon still suffer from drug-related violence, cities such as Cartagena and Medellín are relatively safe. Going on a fully guided group or individual tour can also help you navigate destinations where political unrest or crime might impact your safety.

Travelers should study not only the advisories provided by their own country, but also by the U.S., United Kingdom, and Australia to broaden their understanding of the risks in Level 3 countries, Wen says. As for Level 4 countries, that “Do Not Travel” advice couldn’t be any clearer.

Other countries also issue warnings to their citizens about visiting the U.S. Canada recently informed its LGBTQ travelers they may be affected by laws in certain U.S. states. Australia, meanwhile, cautions its citizens visiting the U.S. to be wary of higher crime rates and gun violence, and even to learn safety strategies for active shooter scenarios.

People who visit countries with Level 3 or Level 4 travel advisories don’t just risk their safety. They also may have travel insurance complications, says Linchi Kwok , tourism management professor at California State Polytechnic University Pomona.

( How travel insurance can—and can’t—help when your plans change .)

They must pay much higher premiums, and their insurance can be invalidated if the advisory for their destination is elevated. “Medical coverage can be minimal, too, particularly if the travel advisory is put up against a disease or an outbreak,” says Kwok. “I encourage Americans to think twice before they travel to Level 3 and especially Level 4 destinations.”

Warnings and their impact on tourism

Travel advisories can be biased, Larsen argues. His research found that, while the U.S. didn’t often overstate the risk of travel to countries with which it had poor relations, it did often understate the danger of visiting nations that were its close allies. Elevating a travel advisory can stoke diplomatic tensions between two countries. Once a country is raised to Level 3 or 4, many tourists will avoid visiting, and many American universities won’t let students join study abroad programs.

The economic ramifications of a level change impact individual businesses such as hotels, restaurants, and travel agencies. For instance, J 2   adventures , a Jewish-focused tour company, saw most of its fall group trips to Israel canceled after the start of the Israel-Hamas war (and the higher advisory level), says cofounder Guy Millo. “This is not just because of the violence on the ground, but because of practical considerations like accessibility of commercial airline flights,” he says. “Most tourists from North America and places around the globe simply couldn’t get here even if they wanted to.”

Evaluating the U.S. Department of State Travel Advisory System

Many colleges and universities, including Northwestern, pay close attention U.S. Department of State (DOS) consular announcements, which are disseminated to the public to help assess travelers’ risks. It’s important for travelers to understand the different announcement types and sources.

The Consular Travel Advisory System

Under new DOS Travel Advisory system every country is assigned a color-coded risk rating from one to four, defined as:

• Level 1 – Exercise Normal Precautions: This is the lowest advisory level for safety and security risk.
• Level 2 – Exercise Increased Caution: Be aware of heightened risks to safety and security. The Department of State provides additional advice for travelers in these areas in the Travel Advisory. 
• Level 3 – Reconsider Travel: Avoid travel due to serious risks to safety and security. The Department of State provides additional advice for travelers in these areas in the Travel Advisory. 
• Level 4 – Do Not Travel: This is the highest advisory level due to greater likelihood of life-threatening risks. During an emergency, the U.S. government may have very limited ability to provide assistance. The Department of State advises that U.S. citizens not travel to the country or leave as soon as it is safe to do so. The Department of State provides additional advice for travelers in these areas in the Travel Advisory.   

Additional country-specific information is provided in each advisory, including clearer, actionable steps for that travelers can take to mitigate risk. (See Risk Indicators below). The DOS will update the advisories as needed, based on changes to security and safety information.

Risk Indicators

By using established risk indicators, the Travel Advisories at levels 2-4 provide clear reasons for the level assigned:

• E - Time-Limited Event:  A short-term event, such as an election, sporting event or other incident that may post a safety risk.  
• C – Crime: Widespread violent or organized crime is present in areas of the country. Local law enforcement may have limited ability to respond to serious crimes.
• T – Terrorism: Terrorist attacks have occurred and/or specific threats against civilians, groups, or other targets may exist.
• U – Civil Unrest: Political, economic, religious, and/or ethnic instability exist and may cause violence, major disruptions, and/or safety risks.
• N – Natural Disaster: A natural disaster, or its aftermath, poses danger.
• H – Health: Health risks, including current disease outbreaks or a crisis that disrupts a country’s medical infrastructure, are present. The issuance of a Centers for Disease Control Travel Notice may be a factor.
• K– Kidnapping or Hostage Taking : Criminal or terrorist individuals or groups have threatened to and / or have seized or detained and threatened to kill,  injure or continue to detain individuals in order to compel a third party (including a governmental organization) to do or abstain from doing something as a condition of release.
• D – Wrongful Detention: The risk of wrongful detention of U.S. nationals by a foreign government exists.
• O – Other: There are potential risks not covered by previous risk indicators.

U.S. embassies and consulates will now issue Alerts to replace the Emergency Messages and Security Messages. Alerts will inform travelers of specific safety and security concerns in a country and will be labeled according to their issue: Security Alert; Health Alert; Weather Alert; or Demonstration Alert. Recent Alerts for a country appear below the Travel Advisory. Alerts can also be found on individual embassy or consulate websites.

Everything you need to know about State Department travel advisories

When traveling abroad, the top concern for many Americans is safety.

Whether it is due to ongoing conflict, special events such as the 2024 Paris Olympics , natural disasters like a volcano currently erupting in Iceland or an uptick in crime , conditions of countries can change rapidly, affecting both travelers and locals.

To help keep American travelers safe, the U.S. Department of State issues and maintains travel advisories for U.S. citizens based on current circumstances.

These advisories can be particularly helpful for first-time and younger travelers, though the agency encourages all people to review them for their desired destination ahead of travel.

What are travel advisories based on?

Although travel warnings originate from the State Department and live on its website , they are a joint effort between the State Department's Office of Overseas Citizens Services and U.S. consulates and embassies worldwide.

"We've got our diplomats and consular officers on the ground in all those places, who have more up-to-date information than anyone in Washington could have," said Angela Kerwin, deputy assistant secretary for Overseas Citizens Services, during a Zoom interview Thursday. "But we use a variety of information in order to look at the criteria that go into our travel advisories around the world."

In addition to crime reports, nongovernmental organization reports and those from international organizations such as the United Nations, the government considers nine risk factors in determining the level at which each country's advisory should be set:

• C — Crime : Widespread violence or organized crime is present in areas of the country. Local law enforcement may have limited ability to respond to serious crimes.
• T — Terrorism : Terrorist attacks have occurred and/or specific threats against civilians, groups or other targets may exist.
• U — Civil Unrest : Political, economic, religious and/or ethnic instability exists and may cause violence, major disruptions and/or safety risks.
• H — Health : Health risks, including current disease outbreaks or a crisis that disrupts a country's medical infrastructure. The issuance of a Centers for Disease Control and Prevention Travel Health Notice may also be a factor.
• N — Natural Disaster : A natural disaster, or its aftermath, poses danger.
• E — Time-limited Event : Short-term events, such as elections, sporting events or other incidents that may pose safety risks.
• K — Kidnapping or Hostage Taking : Criminal or terrorist individuals or groups have threatened to and/or have seized or detained and threatened to kill, injure or continue to detain individuals in order to compel a third party (including a governmental organization) to do or abstain from doing something as a condition of release.
• D — Wrongful Detention : The risk of wrongful detention of U.S. nationals exists.
• O — Other : Potential risks are not covered by previous risk indicators. Read the country's travel advisory for details.

Although the most recently added category, Wrongful Detention, only applies to a handful of countries, it's an important criterion for travelers to note when a country has detained a U.S. citizen without cause.

Level 1 to 4 tiered warning system

Based on that nine-rubric system, plus reports and input from U.S. consulates and embassies in these countries, the agency assigns each country a Level 1 to 4 tiered warning , with 1 being the lowest level, indicating relative safety, and 4 being the highest, meaning travelers should not visit.

Level 1: Exercise normal precautions

This is the lowest level a country can achieve, making it among the safest for Americans to visit. As with any travel, there is always some risk, so every country will always have at least a Level 1 advisory.

Level 2: Exercise increased caution

Under a Level 2 designation, a country has increased safety or security risks, but they likely won't preclude you from traveling there.

Level 3: Reconsider travel

A Level 3 advisory tells travelers to potentially defer trips to the country in question, as serious potential risks exist.

Level 4: Do not travel

The most serious advisories are Level 4 recommendations, which alert you to avoid travel to designated countries and areas due to a greater threat of potentially life-threatening risks and limited resources to help Americans.

What else to know about travel advisories

In addition to the State Department's general travel advisory, a country's information page will also provide any timely alerts from the corresponding U.S. embassy and/or consulate to consider.

There are also certain countries where the agency can provide "carve-outs" to communicate information related to specific areas or regions within a particular country.

"Perhaps the country itself is a Level 3 country, but there is one particular border area that has ongoing kinetic activity of some sort, and we'd say that would be a Level 4," Kerwin explained.

These carve-outs are most often found in Mexico , as the U.S. shares a border with the country and more Americans travel to Mexico for tourism than elsewhere.

"Mexico is a special case. We also have more U.S. consulates than we do in any other country in the world, and for that reason, we are able to provide state-by-state travel advisory levels in Mexico," Kerwin said. "[With] other countries around the world, [we] just simply don't have the ability to have that level of detail; the specificity is greater for Mexico."

Because data is the main source of information for crafting these advisories, not all alerts can be created equally.

"It is impossible to say that we can apply all nine criteria exactly the same in country A as we do in country B. You're going to have more statistical data of a reliable type for ... Germany than you would Chad," Kerwin explained. "So to compare the exact same report for Germany with the exact same report for Chad is not something that makes sense because it's generally not going to be available."

In those cases, the government relies on its embassies and consulates, which are present in most of these countries, to help inform its alerts.

"We've got people on the ground who are often best positioned to help us evaluate the number of kidnappings, the level of civil unrest, how many terrorist attacks reported or not reported," she said.

Note that a lack of readily available or accurate data doesn't make the country inherently riskier or more dangerous for travelers.

"It just means that we don't have the exact type of data that we would have in another country," Kerwin said. "We would have to rely more heavily on embassy reporting and our folks there, but it does not necessarily mean it is a more dangerous country."

Does a Level 4 alert mean I should avoid traveling there?

In short, the answer is yes.

At the time of publication, there were 19 countries with Level 4 alerts, per the State Department.

"These are the places we deem as the most dangerous for U.S. citizens to travel to, and we would really like U.S. citizens to look at other destinations," Kerwin said. In part, that's because of the limited consular or embassy services available in these places should an American need help.

"Every U.S. citizen gets to make up their own mind on where they want to travel. That's all we can do as a government," she continued. "If a U.S. citizen finds themselves in a situation where they need to travel to one of these countries for whatever reason, we would ask that they look at our travel advisories in advance, read our country information sheet. We would certainly recommend if we have a functioning embassy, that they save that information on their phone so they can contact the embassy if necessary."

But overall, travelers should avoid traveling to Level 4 countries if possible.

"Each of these Level 4 countries will tell you what our concerns are with these countries and [that] our criteria has been met," Kerwin said. "We believe it is quite dangerous to go there."

How often are State Department travel advisories updated?

When viewing a travel advisory, you'll note at the top the date it was last updated, as alerts are updated on a rolling basis.

Generally speaking, Level 4 and Level 3 alerts are updated at least once every six months, while Level 1 and Level 2 alerts are examined at least once per year, pending evolving circumstances.

"If something changes or some precipitating event, we would do it earlier as needed," Kerwin said.

For example, on Thursday, the U.S. Embassy in Reykjavik issued its own alert regarding a volcanic eruption in southwest Iceland that morning. When embassy alerts are issued for isolated events in a particular region of a country, it does not necessarily reflect the overall level of the country as a whole.

Despite the volcano warning, Iceland remained at Level 1 , as it has since July. If it had been a more widespread eruption affecting general European air travel, that would have prompted the agency to update the travel advisory as a whole.

"Right now, by sending out that security alert, we're saying stay away from the volcano, but if you wanna go have dinner in Reykjavik, follow our regular information we have on our travel advisory," Kerwin said.

That volcano alert also went out via the agency's Smart Traveler Enrollment Program , which sends relevant security updates from the nearest U.S. Consulate, and which Kerwin advised travelers to enroll in as another way to stay safe abroad.

"So anybody who is registered in STEP traveling to or who is living in Iceland would've gotten an email to say, 'Hey, be aware the volcano erupted again today, we're watching it closely; pay attention,'" she explained. "We have those various security alerts that we can send out at any time in a country based on late-breaking events."

Special events, such as the upcoming 2024 Paris Olympics, will also trigger additional and/or more frequent alerts.

"We will be paying special attention to that. We expect there will be a large number of U.S. citizens that are headed in that direction to cheer on our team, and we want to make sure that we are giving them the best information we can about their time when they're traveling," Kerwin said.

Other things to consider when traveling abroad

As with travel in general, the State Department advises Americans heading overseas to prepare in advance.

"We have a slogan we've been using, and I like it; it's called 'travel smart from the start,' and that starts even before you decide what destination," Kerwin said. That slogan applies to details like checking that you have enough validity on your passport (most countries require six months at the time of entry) and buying travel insurance.

Kerwin also advises procuring the contact information for the nearest U.S. government presence (i.e., the embassy or consulate) via the State Department's list of U.S. embassies and consulates .

"Jot down on paper, take a picture on your phone and save the U.S. Embassy/Consulate phone number or email address so you can get in contact with us if there's a problem," she said. "And always be aware of your surroundings ... a heightened level of awareness ... is important for travelers no matter where they're going."

Bottom line

With travel comes an inherent risk, and the government aims to help travelers remain safe domestically and abroad.

While the decision to travel is ultimately up to the traveler, these travel advisories should be taken seriously.

"Our goal is to always provide the best advice and information we can for U.S. citizens so they can make their decisions as to where they wish they travel," Kerwin said.

Therefore, heed these travel warnings from the State Department via U.S. embassies, consulates and the department's STEP program.

"The final thing — and this is an important one — is to have fun," Kerwin added. "Travel is fantastic — you get to see new cultures, and you get to experience new languages and beautiful countries and beautiful cities. We want U.S. citizens to travel and have fun on their adventures around the world."

The CDC's 'Level 4' Travel Advisory List Now Includes 140 Countries

More than half of the world's destinations are on the CDC's list

Jalyn Robinson is the assistant travel editor at Dotdash Meredith, working for both Travel + Leisure and TripSavvy. She started at TripSavvy in 2021 and joined Travel + Leisure in 2023, where she writes, edits, and assists with other editorial operations. 

The Centers for Disease Control and Prevention (CDC) has moved even more countries to its "very high risk" travel list. Since Feb. 22, the organization has added four more countries to its "Level 4" advisory—Bhutan, Brunei, Iran, and Malaysia—bringing the total number of countries on the list to 140, more than half of the world's destinations.

The CDC changed its three-level advisory system to a four-level system in November 2020. According to the system, a "Level 1" advisory signifies a low level of COVID-19, and the CDC recommends that all travelers to these locations be vaccinated; "Level 2" indicates a moderate level of COVID-19, and the CDC warns unvaccinated travelers to avoid nonessential trips to these destinations; "Level 3" indicates a high level of COVID-19 and the CDC recommends unvaccinated travelers avoid travel under any circumstance, and finally, "Level 4" indicates a very high level of COVID-19 and the CDC recommends that everyone, regardless of vaccination status, should avoid travel to any country under this advisory. To receive a "Level 4" advisory, a country must have more than 500 new cases per 100,000 residents over the past 28 days.

The advisory lists are updated weekly, and the agency notes on its website, "additional information such as new variants of concern, vaccination rates, hospitalizations, and imported case counts may be considered when determining a Travel Health Notice level."

The United States Department of State has followed suit with the CDC; it moved the same countries—except Brunei—onto its "Level 4" advisory list on Feb. 22.

Despite the high-level advisories, many countries are still planning to open their borders and take travelers in. Thailand is set to reopen its borders to vaccinated tourists on March 15.

Travel Health Notices

Search By Country Name or Disease

CDC uses Travel Health Notices (THNs) to inform travelers about global health risks during outbreaks, special events or gatherings, and natural disasters, and to provide advice about protective actions travelers can take to prevent infection or adverse health effects.

A THN can be posted for: 1) a disease outbreak (higher number of expected cases) in a country or region, 2) sporadic cases of a disease in an unusual or new geographic location, 3) natural and human-made disasters with severe environmental health risks, or infrastructure damage that would limit healthcare services availability and 4) mass gathering events that can lead to disease outbreaks.

U.S. issues travel warning for major European country over fears of terrorist activity

• Updated: May. 02, 2024, 5:41 p.m. |
• Published: May. 02, 2024, 3:54 p.m.

The U.S. State Department warns that travelers to Germany should exercise extreme caution on their visit. The travel advisory issued Wednesday was issue over concerns about terrorist activity. Seen here is the Neuschwanstein castle, in Schwangau, an iconic sight in the central European nation.

• Robert Higgs, cleveland.com

WASHINGTON – A new advisory from the U.S. State Department warns European travelers to exercise increased caution if they visit Germany for fear of terrorist activity.

The warnings were contained in an advisory issued Wednesday that said terrorist groups continue to plan attacks in Germany and may strike with little or no warning.

“They target tourist locations and transportation hubs,” the advisory states. “They also target markets/shopping malls and local government facilities. They target hotels, clubs, and restaurants. They also attack places of worship, parks, and major sporting and cultural events. They target schools, airports, and other public areas.”

The advisory is a Level Two warning that calls for exercising increased caution. Level Three (Reconsider Travel) and Level Four (Do Not Travel) advisories are the two more serious levels.

But the Level Two advisory for Germany is unusual. It is a large nation in central Europe with a thriving economy and a population second only to Russia.

The only more serious warnings issued in the last year for European travel were for countries impacted by the war in Ukraine. Do-not-travel warnings were issued for Ukraine (May 2023), Belarus (July 2023) and Russia (September 2023) in connection with the fighting.

The State Department cautions that U.S. citizens traveling to Germany should take the following measures:

• Be aware of your surroundings when traveling to tourist locations and crowded public venues.
• Follow instructions of local authorities.
• Monitor local media for breaking events and adjust plans based on new information.
• Enroll in the Smart Traveler Enrollment Program ( STEP ) to receive Alerts and make it easier to locate you in an emergency.
• Review the State Department’s Country Security Report for Germany.
• Visit the Centers for Disease Control and Prevention online to learn the latest Travel Health Information related to your travel.
• Prepare a contingency plan for emergency situations. Review the State Department’s Traveler’s Checklist .

Travelers may also want to follow the State Department on  Facebook  and  Twitter for any updates, the advisory states.

U.S. reissues Level 2 travel warning for Germany. Here’s what you need to know before your next trip

The U.S. State Department has reissued a Level 2 travel advisory for Germany due to fears of terrorism.

The State Department issued the advisory on Wednesday, ranking the travel advisory on a scale of two out of four. This means that those traveling to an area must “exercise increased caution.”

“Terrorists may attack with little or no warning,” the State Department noted.

The agency added that terrorists could target tourism and transportation hubs, as well as shopping destinations, hotels, clubs, restaurants, local government facilities and major events.

The State Department noted on its website that for those who do decide to travel to Germany, travelers should pay attention to their surroundings , follow the instructions of local authorities, be aware of the latest breaking news in the area and adjust your plans, if necessary. The organization also urges travelers to Germany to create a contingency plan for emergency situations as well as sign up for the  Smart Traveler Enrollment Program  ( STEP ) to receive alerts and make it easier for the State Department to locate you in case of an emergency.

The U.S. Department of State has issued several travel warnings this year with those most recently centered around the Caribbean.

One was a Level 4 “do not travel” warning against traveling to the country of Haiti due to kidnappings and gang violence.

Another warning from the State Department cautioned travelers to “reconsider travel” to the country of Jamaica after 65 people were murdered in one month.

U.S. issues travel warning for major European country: ‘Terrorist groups keep planning attacks’

• Updated: May. 04, 2024, 12:12 p.m. |

The U.S. State Department has issued a new advisory urging travelers to Europe to be extra vigilant when visiting Germany due to concerns about potential terrorist activity.

The advisory, a Level Two – which suggests heightened caution— was released on May 1 and highlights ongoing threats from terrorist groups in Germany, cautioning travelers to remain alert as attacks could occur with minimal warning, noting that “terrorist groups keep planning attacks in Germany.”

The advisory states: “They target tourist locations and transportation hubs. They also target markets/shopping malls and local government facilities. They target hotels, clubs, and restaurants. They also attack places of worship, parks, and major sporting and cultural events. They target schools, airports, and other public areas.”

For reference, Level Three (Reconsider Travel) and Level Four (Do Not Travel) advisories represent more critical levels. However, Germany’s Level Two advisory is noteworthy, given its significant size in central Europe, robust economy, and second-largest population after Russia.

Over the past year, the most severe travel advisories in Europe were primarily linked to the conflict in Ukraine. Do-not-travel advisories were issued for Ukraine (May 2023), Belarus (July 2023), and Russia (September 2023) due to the ongoing hostilities.

If you must travel to Germany, the State Department recommends:

• Be aware of your surroundings when traveling to tourist locations and crowded public venues.
• Follow the instructions of local authorities.
• Monitor local media for breaking events and adjust your plans based on new information.
• Enroll in the Smart Traveler Enrollment Program ( STEP ) to receive Alerts and make it easier to locate you in an emergency.
• Follow the Department of State on  Facebook  and  Twitter .
• Review the Country Security Report for Germany.

The U.S. Department of State issued a level 2 advisory for Germany this week, which urgers travelers to “exercise increased caution.”

“Terrorist groups keep planning attacks in Germany,” U.S. officials said in the advisory. “Terrorists may attack with little or no warning. They target tourist locations and transportation hubs. They also target markets/shopping malls and local government facilities. They target hotels, clubs, and restaurants. They also attack places of worship, parks, and major sporting and cultural events. They target schools, airports, and other public areas.”

Level 3 and level 4 advisories denote “reconsider travel” and “do not travel.” Those thresholds have not been met.

But the level 2 advisory for Germany is unusual since it is a large nation in central Europe with thriving economy and tourism and a population second only to Russia.

The only more serious warnings issued in the last year for European travel were for countries impacted by the war in Ukraine. Do-not-travel warnings were issued for Ukraine (May 2023), Belarus (July 2023) and Russia (September 2023) in connection with the fighting.

If you decide to travel to Germany:

• Be aware of your surroundings when traveling to tourist locations and crowded public venues.
• Follow the instructions of local authorities.
• Monitor local media for breaking events and adjust your plans based on new information.
• Enroll in the Smart Traveler Enrollment Program ( STEP ) to receive Alerts and make it easier to locate you in an emergency.
• Follow the Department of State on  Facebook  and  Twitter .
• Review the Country Security Report for Germany.
• Visit the CDC page for the latest Travel Health Information related to your travel.

The huge solar storm is keeping power grid and satellite operators on edge

NASA's Solar Dynamics Observatory captured this image of solar flares early Saturday afternoon. The National Oceanic and Atmospheric Administration says there have been measurable effects and impacts from the geomagnetic storm.

Planet Earth is getting rocked by the biggest solar storm in decades – and the potential effects have those people in charge of power grids, communications systems and satellites on edge.

The National Oceanic and Atmospheric Administration says there have been measurable effects and impacts from the geomagnetic storm that has been visible as aurora across vast swathes of the Northern Hemisphere. So far though, NOAA has seen no reports of major damage.

The Picture Show

Photos: see the northern lights from rare, solar storm.

There has been some degradation and loss to communication systems that rely on high-frequency radio waves, NOAA told NPR, as well as some preliminary indications of irregularities in power systems.

"Simply put, the power grid operators have been busy since yesterday working to keep proper, regulated current flowing without disruption," said Shawn Dahl, service coordinator for the Boulder, Co.-based Space Weather Prediction Center at NOAA.

"Satellite operators are also busy monitoring spacecraft health due to the S1-S2 storm taking place along with the severe-extreme geomagnetic storm that continues even now," Dahl added, saying some GPS systems have struggled to lock locations and offered incorrect positions.

NOAA's GOES-16 satellite captured a flare erupting occurred around 2 p.m. EDT on May 9, 2024.

As NOAA had warned late Friday, the Earth has been experiencing a G5, or "Extreme," geomagnetic storm . It's the first G5 storm to hit the planet since 2003, when a similar event temporarily knocked out power in part of Sweden and damaged electrical transformers in South Africa.

The NOAA center predicted that this current storm could induce auroras visible as far south as Northern California and Alabama.

Around the world on social media, posters put up photos of bright auroras visible in Russia , Scandinavia , the United Kingdom and continental Europe . Some reported seeing the aurora as far south as Mallorca, Spain .

The source of the solar storm is a cluster of sunspots on the sun's surface that is 17 times the diameter of the Earth. The spots are filled with tangled magnetic fields that can act as slingshots, throwing huge quantities of charged particles towards our planet. These events, known as coronal mass ejections, become more common during the peak of the Sun's 11-year solar cycle.

A powerful solar storm is bringing northern lights to unusual places

Usually, they miss the Earth, but this time, NOAA says several have headed directly toward our planet, and the agency predicted that several waves of flares will continue to slam into the Earth over the next few days.

While the storm has proven to be large, predicting the effects from such incidents can be difficult, Dahl said.

Shocking problems

The most disruptive solar storm ever recorded came in 1859. Known as the "Carrington Event," it generated shimmering auroras that were visible as far south as Mexico and Hawaii. It also fried telegraph systems throughout Europe and North America.

Stronger activity on the sun could bring more displays of the northern lights in 2024

While this geomagnetic storm will not be as strong, the world has grown more reliant on electronics and electrical systems. Depending on the orientation of the storm's magnetic field, it could induce unexpected electrical currents in long-distance power lines — those currents could cause safety systems to flip, triggering temporary power outages in some areas.

The storm is also likely to disrupt the ionosphere, a section of Earth's atmosphere filled with charged particles. Some long-distance radio transmissions use the ionosphere to "bounce" signals around the globe, and those signals will likely be disrupted. The particles may also refract and otherwise scramble signals from the global positioning system, according to Rob Steenburgh, a space scientist with NOAA. Those effects can linger for a few days after the storm.

Like Dahl, Steenburgh said it's unclear just how bad the disruptions will be. While we are more dependent than ever on GPS, there are also more satellites in orbit. Moreover, the anomalies from the storm are constantly shifting through the ionosphere like ripples in a pool. "Outages, with any luck, should not be prolonged," Steenburgh said.

What Causes The Northern Lights? Scientists Finally Know For Sure

The radiation from the storm could have other undesirable effects. At high altitudes, it could damage satellites, while at low altitudes, it's likely to increase atmospheric drag, causing some satellites to sink toward the Earth.

The changes to orbits wreak havoc, warns Tuija Pulkkinen, chair of the department of climate and space sciences at the University of Michigan. Since the last solar maximum, companies such as SpaceX have launched thousands of satellites into low Earth orbit. Those satellites will now see their orbits unexpectedly changed.

"There's a lot of companies that haven't seen these kind of space weather effects before," she says.

The International Space Station lies within Earth's magnetosphere, so its astronauts should be mostly protected, Steenburgh says.

In a statement, NASA said that astronauts would not take additional measures to protect themselves. "NASA completed a thorough analysis of recent space weather activity and determined it posed no risk to the crew aboard the International Space Station and no additional precautionary measures are needed," the agency said late Friday.

While this storm will undoubtedly keep satellite operators and utilities busy over the next few days, individuals don't really need to do much to get ready.

"As far as what the general public should be doing, hopefully they're not having to do anything," Dahl said. "Weather permitting, they may be visible again tonight." He advised that the largest problem could be a brief blackout, so keeping some flashlights and a radio handy might prove helpful.

And don't forget to go outside and look up, adds Steenburgh. This event's aurora is visible much further south than usual.

A faint aurora can be detected by a modern cell phone camera, he adds, so even if you can't see it with your eyes, try taking a photo of the sky.

The aurora "is really the gift from space weather," he says.
