This update includes moving 33 countries, including Iceland, Israel and Singapore, into the lowest-risk category.
The CDC’s revised travel health declaration guidelines seek to “better distinguish countries with severe outbreak situations” from countries where Covid-19 “remains but is under control”.
The CDC’s threat level is determined by the number of Covid-19 cases in a country at each level. But recommendations for unvaccinated people vary according to the severity of the pandemic from country to country.
The CDC recommends avoiding travel to countries at level 4, the highest threat level. With more than 500 cases per 100,000 inhabitants in the past 28 days, top 4 countries include countries such as Brazil, India and Iraq.
For Tier 3 countries such as Mexico, Russia and Iran, the CDC does not recommend non-essential travel for unvaccinated people. These countries currently report 100 to 500 cases per 100,000 inhabitants.
At Level 2, the agency recommends that unvaccinated travelers who are at high risk of serious illness from Covid-19 should avoid visiting. These countries, such as Finland, Cambodia and Kenya, are reporting 50-99 cases per 100,000.
Finally, Tier 1 countries such as Australia and New Zealand It is considered the lowest risk destination. And fewer than 50 COVID-19 cases have been reported in the past 28 days. The CDC still recommends vaccination before traveling to low-risk locations.
