You might want to rethink your Christmas market plans—the U.S. Centers for Disease Control and Prevention just moved four popular European destinations to the highest warning level for travel (Level 4: Very High Risk).

The four European destinations that were moved up to level four are:

• Czech Republic

• Guernsey

• Hungary

• Iceland

These destinations have had more than 500 reported cases of COVID-19 per 100,000 residents in the past 28 days, which bumps them up from Level 3.

However, if you’re planning a warm weather winter getaway, you’re in luck, as the Bahamas, Bolivia, and Papua New Guinea were all moved down this week from Level 4 to Level 3. Level 3 countries have had between 100 and 500 COVID cases per 100,000 residents in the past 28 days.

In other good news, India and Japan were both moved down to Level 1, the CDC’s lowest warning level for travel.

If you are planning to travel internationally, remember that the United States recently changed the entry rules for all travelers (including returning U.S. citizens). Fully vaccinated travelers must now show proof of vaccination and a negative COVID test taken no more than three days before travel. Unvaccinated travelers must show a negative COVID test result taken no more than one day before travel.
