The Centers for Disease Control and Prevention added seven destinations to the highest tier of its travel risk list. The "Level 4: COVID-19 Very High" list now includes Puerto Rico, Switzerland, Azerbaijan, Estonia, Guam, North Macedonia, and Saint Lucia.
Locations in Level 4 are reporting more than 500 cases of COVID-19 per 100,000 residents over the past 28 days. The CDC advises that people avoid all travel to those places.
"Travel increases your chance of getting and spreading COVID-19," CDC spokeswoman Caitlin Shockey told the Washington Post. "You may feel well and not have any symptoms, but you can still spread COVID-19 to others. Staying home is the best way to protect yourself and others from COVID-19."
Six countries, Bahrain, Indonesia, Namibia, Oman, Rwanda, and Zimbabwe, were moved from Level 4 down to Level 3. Bermuda, Canada, Germany, and Moldova moved up from Level 2. Nonessential travel is not recommended to destinations in Level 3, but the CDC said that if you have to travel to those countries, you should be fully vaccinated.
The CDC updates the list every week based on the latest data from the World Health Organization and other official sources. Countries that do not provide health information are categorized as "unknown," and the CDC says travelers should treat those nations as if they are Level 4.
