At the advice of the United States Centers for Disease Control and Prevention (CDC), America has now added three additional Caribbean countries to its highest travel warning level.

The CDC on Monday (August 23) raised an additional six destinations to its highest travel warning level, including popular vacation hotspots, The Bahamas and Saint Maarten as well as problem-plagued, Haiti.

The health and safety agency raised the Caribbean territories to a Level 4, warning travellers that they should avoid travelling to the island nations, especially if they are unvaccinated.

Destinations are classified as a Level 4 if there are 500 COVID-19 cases per 100,000 people.

Mirroring the CDC’s travel advisory the U.S Department of State also issued a travel warning for the named Caribbean countries.

According to the state department’s advisory due to the current situation in these countries, even fully vaccinated travellers may be at risk for getting and spreading COVID-19 variants.

As a result, travellers should follow recommendations or requirements in these countries, including wearing a mask and staying 6 feet apart from others.

Other than the named Caribbean countries the CDC also raised, Kosovo, Lebanon and Morocco to a Level 4 travel advisory.

In recent weeks the CDC has raised several countries and territories around the world to its highest COVID-19 warning level including France, Israel, Greece and the U.S. Virgin Islands.

The CDC also waived warnings on a few destinations lowering both India and Canada to Level 2, indicating a “moderate” level of coronavirus transmission.

While the CDC and State Department update travel warnings based on epidemiological situations, the U.S. as a whole continues to heavily restrict international travel.

Last week, the U.S. extended the land border closure with Canada and Mexico another month and non-essential travel for non-U.S. citizens remains restricted from several destinations, including the United Kingdom and European Union.
