The  Bahamas and Sint Maarten, popular cruise ship destinations are included in the CDC's updated travel advisory list for COVID with six nations moving up to Level 4 status, reports CNN.

Ending up in the "Very High" risk category means that these destinations have had more than 500 new COVID cases per 100,000 residents over the last 28 days. If you absolutely have to travel to any of these places, the CDC warns you to "make sure you are fully vaccinated" first. Two of the locations on the Level 4 list are popular vacation destinations for Americans, especially cruise ship travelers. Other stay-away countries are Haiti, Morocco, Kosovo, and Lebanon.
