(CNN) — On Tuesday, the U.S. Centers for Disease Control and Prevention added three islands to the “high” risk category for travelers.
Anguilla, Jamaica and the Turks and Caicos Islands have been upgraded to Level 3, or “high” risk of contracting Covid-19.
The Level 3 risk category “high” is now the top tier in terms of risk level. Level 2 is considered “moderate” risk and Level 1 is considered “low” risk.
Tier 4, previously the highest risk category, is now reserved for special circumstances only, such as an extremely high number of cases, the emergence of a new option of concern, or the collapse of the healthcare infrastructure. So far, under the new system, no destination has been placed at level 4.
As a reminder, the three destinations moved into the “high” risk column on Tuesday are:
• Anguilla
• Jamaica
• Turks and Caicos
All three destinations have moved from the second level.
The Tier 3: High Covid-19 category now applies to countries with more than 100 cases per 100,000 inhabitants in the last 28 days.
As of May 31, there were about 110 destinations at level 3. Tier 3 locations now account for just under half of the approximately 235 locations tracked by the CDC.
Most of the Caribbean is currently at Tier 3, with a few exceptions including Cuba, the Dominican Republic and Saint Kitts and Nevis, which moved to Tier 2 on Tuesday.
Level 3
Many other popular tourist destinations are also on level 3.
With the start of the summer tourist season, much of Europe has stubbornly stuck there. As of May 31, the following popular European destinations remained at level 3:
• France
• Germany
• Greece
• Ireland
• Italy
• Netherlands
• Portugal
• Spain
• United Kingdom
It’s not just the European favorites that make it to level 3. Numerous well-known tourist destinations around the world are in the high-risk category, including the following:
• Brazil
• Canada
• Costa Rica
• Malaysia
• South Korea
• Thailand
