Level 4 destinations and more

Europe is being hit with a ferocious wave of the pandemic, forcing a number of nations to reimpose restrictions to help curb infection rates. Denmark and particularly Germany are among the latest countries to high case numbers in the past week, with the German government in talks to consider a national lockdown to deal with the crisis.

The advisories aim to inform US residents about risks associated with traveling overseas, so people can make better-informed decisions about travel and enjoy relatively safe trips. If you plan to travel soon, here’s what you need to know about the latest travel guidelines.

What is a travel advisory?

The ongoing risks associated with COVID-19, particularly as new variants emerge, present challenges and uncertainties for travel. To make the experience a little less confusing, the Department of State has aligned its security travel advisories with the CDC’s science-based Travel Health Notices to warn travelers about dangers and COVID-19 threats overseas.

Level 4 travel advisory

Level 4 is the highest alert. Countries that register more than 500 new cases of COVID-19 over the past 28 days per 100,000 population are designated to the CDC’s Level-4 list. Under CDC guidelines, people are asked to “avoid travel” to Level 4 destinations—but if they must travel, they should be fully vaccinated.

The Department of State takes this information into account, also looking at factors such as political instability, natural disasters and the threat of terrorism or violent crime. “[Level 4] is the highest advisory level due to greater likelihood of life-threatening risks,” the Department explains. In the context of COVID-19, Americans are urged to avoid travel to these places due to increased infection rates and COVID-19 variants.

What countries are at Level 4?


Case numbers have been rising in Germany among unvaccinated people and older citizens whose immunity have started to wane. Officials are restricting movement of unvaccinated people but according to Reuters, the government could reintroduce a national lockdown in the coming days. Some of the much-loved Christmas markets that pop up each winter have already been cancelled. Borders are open in Germany and Americans are permitted to travel there if they’re vaccinated, as per Germany’s entry rules.


Denmark is now facing a third wave of the pandemic and has reintroduced its ‘corona pass’ that requires individuals to show proof of vaccination before entering many public spaces. Denmark has a relatively high vaccination rate and so far festive traditions such as the Tivoli Christmas market in Copenhagen are going ahead.

Other destinations at Level 4 include the Ireland, the UK, Cuba, Costa Rica, the Czech Republic, the Netherlands, Switzerland, Turkey, Barbados, Belize, French Polynesia, Greece, Costa Rica and more.

Level 3 advisory

The CDC advises unvaccinated Americans to avoid nonessential travel to Level 3 destinations, where risks associated with COVID-19 remain high. Some popular destinations designated Level 3 include Italy, Cyprus, Canada, Chile, Croatia, Colombia, Egypt, Aruba, Sweden, Mexico, Japan, Sweden, Denmark, Australia and—most recently—Israel, Thailand, Panama, Portugal, Spain, and Brazil.

Level 2 advisory

Level 2 places are considered “COVID-19 moderate” destinations by the CDC. When traveling to these places people are asked to “practice enhanced precautions”. The CDC also urges unvaccinated people who are at increased risk for severe illness from COVID-19 to avoid nonessential travel to Level 2 destinations. Some countries currently at Level 2 include New Zealand, Peru, South Korea, India, Zimbabwe, and Nepal.

Should I cancel my trip to a Level 4 country?

The answer is up to you. Travel advisories are guidelines, not rules. You are still permitted to travel to these places, but if you choose to go a country the government is advising you to avoid, you do so at your own risk. In some extreme cases—that is, countries where there is civil unrest, widespread violence and political instability—the Department warns that some consular services may not be available to you and advises travelers to “always have a contingency plan for emergency situations”.

If I do travel, do I need to quarantine?

It depends on your destination. These travel advisories and travel health notices are set out by the US government and the CDC, not the governments of the individual countries. For example, Ireland is at Level 4 but the Irish government is permitting Americans to travel there.

How often do these advisories change?

The Department of State confirms it reviews and updates travel advisories “as needed, based on security and safety information.”

How to resist the urge to travel during the coronavirus pandemic

Anyone considering heading abroad should read the entire travel advisory for their destination at Travel.State.gov; in addition to the destination’s border restrictions and entry requirements—and stay up-to-date on local public health guidelines.
