The Centers for Disease Control and Prevention updated its list of travel guidance amid the coronavirus pandemic on Tuesday (August 24). The agency six countries to the "Level 4: COVID-19 Very High" list, bringing the total number to 80. The new additions include the Bahamas, Sint Maarten, Haiti, Kosovo, Lebanon, and Morocco.
According to the CDC, countries that are considered Level 4 have recorded at least 500 cases per 100,000 residents over the past 28 days.
"Avoid travel to these destinations. If you must travel to these destinations, make sure you are fully vaccinated before travel," the CDC advised.
The agency also added ten countries to Level 3, including Greenland and Guernsey. Paraguay was moved down to Level 3 after being listed in Level 4. Bulgaria and Serbia were moved up to Level 3 from Level 2, while Albania, Bosnia, Herzegovina, Brunei, and Liechtenstein were moved up from Level 1.
Those countries have reported between 100-500 cases of COVID-19 for every 100,000 residents over the past 28 days.
The CDC advised against any international travel for anybody who is not fully vaccinated.
"Fully vaccinated travelers are less likely to get and spread COVID-19. However, international travel poses additional risks, and even fully vaccinated travelers might be at increased risk for getting and possibly spreading some COVID-19 variants," the agency said.
