The U.S. Centers for Disease Control and Prevention updated its travel advisories and put US territories Puerto Rico and Guam in its highest risk tier. Puerto Rico and Guam ‘Level 4: Covid-19 Very High’ list, along with St Lucia, Azerbaijan, Estonia, North Macedonia and Switzerland.
Destinations are placed in the Level 4 category if they have reported more than 500 new Covid-19 cases per 100,000 residents over the past 28 days. Americans should avoid travel to these destinations, the CDC says.
