a high risk of COVID-19, including Australia, Israel, the Bahamas and the British Virgin Islands.
The Centers for Disease Control and Prevention moved 22 countries to its “level 4” travel health notice tier Tuesday, signaling that travelers should “avoid travel to these destinations” regardless of vaccination status.
“If you must travel to these destinations, make sure you are fully vaccinated before travel,” the CDC says on its website.
The countries considered to have a “very high” risk of COVID-19 include:
Canada, France and the United Kingdom.
The CDC looks at incidence rates and new case trajectories to determine each country’s COVID-19 risk. Countries are bumped to the level 4 tier when they report more than 500 new cases per 100,000 people over the past 28 days.
