The U.S. Centers for Disease Control and Prevention, CDC, on Tuesday warned Americans against travel to Jamaica.

The move comes amid a rising number of Covid-19 cases in the island.

The United States is a major tourism source market for Jamaica.

The federal agency has also warned against travel to Sri Lanka and Brunei.

The CDC raised its travel advisory to a Level 4: Very High for the named countries, warning all US citizens to avoid travel to the destinations.

Meanwhile, the CDC has relaxed its ratings for the Netherlands, Malta, Guinea and United Arab Emirates from Level 4: Very High to Level 3: High.

The Level 3 designation specifically warns unvaccinated Americans to avoid travel to those destinations.

The CDC has also raised its Australia advisory from Leve1: Low to Level 2: Moderate.

In addition, the public health agency has raised its advisory level for Anguilla, Antigua and Barbuda, Benin, Ghana, Grenada, Turks and Caicos Islands to a Level 3.

The CDC issues travel recommendations by countries and for U.S. territories. It does not list recommendations for individual U.S. states.

Several US states are currently experiencing a surge in Covid-19 cases.

The CDC lists about 80 destinations out of around 200 ranked as Level 4, including some U.S. territories.

Efforts to get a comment from Jamaica’s Tourism Ministry were not successful.
