Turkey and Montenegro are now among the highest-risk destinations for travelers, according to the US Centers for Disease Control and Prevention’s regularly revised travel advisories list.

Travel should be avoided to locations carrying the “Level 4: Covid-19 very high” notice, according to CDC guidance. Anyone who must travel should be fully vaccinated first, the agency advises.

The four destinations added to the Level 4 list on August 16 are:

  • Azerbaijan
  • Estonia
  • Guam
  • North Macedonia
  • Puerto Rico
  • Saint Lucia
  • Switzerland

The CDC’s evolving list of travel notices ranges from Level 1 (“low”) to Level 4 (“very high”).

Destinations that fall into the “Covid-19 very high” Level 4 category have had more than 500 cases per 100,000 residents in the past 28 days, according to CDC parameters. The Level 3 category applies to destinations that have had between 100 and 500 cases per 100,000 residents in the past 28 days.

The Bahamian prime minister implemented a pandemic curfew on Saturday, August 21, in place from 8 p.m. to 5 a.m. in mainland Exuma, Abaco and the Abaco Cays, and North, Central and South Andros. Amid the aftermath of the 7.2-magnitude earthquake that struck the southwest of Haiti August 14, the country’s prime minister reminded citizens to be conscious of Covid-19 risk during recovery efforts.

New ‘Level 3’ destinations

Five destinations on Monday moved to the “Level 3: Covid-19 high” category: Chile, Mozambique and Uruguay (all moving down from Level 4), as well as Kosovo and North Macedonia (both moving up from Level 2).

Bermuda, Canada, Germany and Moldova moved up from Level 2. Bahrain, Indonesia, Namibia, Oman, Rwanda and Zimbabwe moved down from Level 4.

CDC guidance for Level 3 destinations urges unvaccinated travelers to avoid nonessential travel to those locations.

In its wider travel guidance, the CDC recommends against all international travel until you are 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.

You can view the CDC’s risk level of any destination on its travel recommendations page.
