The Centers for Disease Control and Prevention has updated its health advice for travel to six countries it now considers to be “very high” risk given the rapid spread of the coronavirus and the Delta variant. It is suggesting that people avoid traveling to these countries altogether, or if they must go, to get vaccinated beforehand.
The six countries — Haiti, Kosovo, Lebanon, Morocco, the Bahamas and St. Martin in the Caribbean — have all had more than 500 cases per 100,000 residents in the past 28 days, pushing them into the C.D.C.’s highest warning category.
Several other countries, including Brazil, Britain and Georgia — which currently has the highest daily global average, at 126 new cases a day per 100,000 people, according to the Center for Systems Science and Engineering at Johns Hopkins University — were already on the list.
The warnings come as the rapid spread of the Delta variant has upended travel plans for Americans amid a summer that many had hoped would include more freedoms thanks to high vaccination rates.
“Even fully vaccinated travelers may be at risk for getting and spreading Covid-19 variants,” the C.D.C. warns on its site. The agency also recommends against any international travel without full vaccination.
“The Covid-19 situation, including the spread of new or concerning variants, differs from country to country,” the agency says. “All travelers need to pay close attention to the conditions at their destination before traveling.”
