The U.S. Centers for Disease Control and Prevention has raised its travel warning level for seven destinations, including Switzerland and Puerto Rico, to its highest risk designation.
Switzerland and Puerto Rico, along with Azerbaijan, Estonia, Guam, North Macedonia and St. Lucia, are now on the CDC's Level 4 list, indicating "very high" Covid-19 risk and for U.S. residents to avoid travel to those destinations. About 80 destinations in total currently are rated Level 4 by the CDC.
The CDC also has raised its warning level for travel to four destinations -- Canada, Germany, Bermuda and Moldova -- to Level 3, indicating "high" Covid-19 risk that unvaccinated travelers should avoid. Those destinations previously had been designated Level 2, indicating "moderate" risk.
In addition, the CDC moved Indonesia, Bahrain, Oman, Namibia, Rwanda and Zimbabwe down to Level 3 from Level 4.
