(CNN) — Norway on Monday moved into the highest-risk category on the US Centers for Disease Control and Prevention’s list of travel advisories for destinations around the world.
The Scandinavian country moved up to “Level 4: Covid-19 Very High” just as the country relaxed most of its domestic Covid-related restrictions over the weekend. Neighbors Sweden and Denmark are listed in the CDC’s Level 3 category.
In Eastern Europe, Bulgaria also moved into the Level 4 category on Monday.
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 criteria.
Both Norway and Bulgaria were previously listed as “Level 3: Covid-19 High.” 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 two new destinations added to Level 4 on September 27 are:
New Level 3 destinations
Six destinations moved to Level 3 on September 27:
• Equatorial Guinea
• Saint Barthelemy
Three places moved down from Level 4: Bangladesh, Panama and Saint Barthelemy (St. Barts).
The other three moved up into the higher-risk Level 3 category. Equatorial Guinea moved up from a previous Level 1 designation, and Singapore and Slovakia moved up from Level 2.
Destinations carrying the “Level 2: Covid-19 Moderate” designation have seen 50 to 99 Covid-19 cases per 100,000 residents in the past 28 days.
“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.
