The US Centre for Disease Control and Prevention (CDC) warned Americans on Monday not to travel to Croatia, Armenia, Austria, Barbados and Latvia due to the Covid-19 situation.
The CDC raised its travel recommendations to “level 4, very high” and told Americans that they should avoid traveling to those five countries.
The CDC has also reduced travel recommendations to “level 3” for Morocco, Argentina, France, Iceland, Lesotho, Nepal, Portugal and South Africa but advises its citizens to get fully vaccinated before the trip.
The CDC's travel alerts, like those from the U.S. State Department, are recommendations, not restrictions. Travelers may continue to fly to the destinations subject to the countries' Covid-19 restrictions and must provide proof of a negative coronavirus test to board international flights back to the United States, even if vaccinated.
