The U.S. Centers for Disease Control and Prevention this week raised its Covid-19 risk warning level to Level 4, the highest level, for 12 countries, including Mexico, Brazil and Singapore.
A Level 4 warning indicates a "very high" risk to travelers due to Covid-19 infection rates, and the CDC recommends avoiding travel to countries with that designation. The latest additions—which also include Anguilla, Chile, Ecuador, French Guiana, Kosovo, Moldova, Paraguay, Saint Vincent and the Grenadines and the Philippines—bring the total list of countries rated Level 4 to about 130. The CDC added Canada to the list earlier this month.
The CDC this week also moved several countries to Level 3, the level at which it recommends travelers to be fully vaccinated and for unvaccinated travelers to avoid nonessential trips. Those include Bhutan, Brunei, Comoros, French Polynesia, Guinea, Guinea-Bissau, Honduras, Liberia, Nepal, Oman and the Gambia.
Only 15 destinations remain rated as either the "moderate" Level 2 or "low" Level 1 risk by the CDC.
