(CNN) — Two tropical islands half a world apart and popular with tourists — Jamaica in the Caribbean and Sri Lanka in South Asia — are now among the highest-risk destinations for travelers.
Also joining the bulging highest-risk list during a global swell of Delta variant cases is the isolated nation of Brunei on the island of Borneo.
People should avoid traveling to locations designated with the “Level 4: Covid-19 Very High” notice, the CDC recommends. Anyone who must travel should be fully vaccinated first, the agency advises.

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 criteria. 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 Bahamas
— Costa Rica
— South Africa

Level 3: High risk
Also on Tuesday, 10 nations were newly assigned to the CDC’s “Level 3: Covid-19 High” category. A big mover popular with the luxury travel set was the little Caribbean resort island of Anguilla.
It had been at “Level 1: Low” and had maintained strict protocols on arriving tourists throughout the pandemic. Visitors must be fully vaccinated to enter and still must take a Covid-19 test and quarantine.
The other places moved up to Level 3 on Tuesday were:
— Antigua and Barbuda (up from Level 2)
— Benin (up from Level 1)
— Ghana (up from Level 2)
— Grenada (up from Level 1)

Not vaccinated? Don’t go
“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.
