The Centers for Disease Control and Prevention is urging travelers to steer clear of seven more countries that it deems to be high risk for contracting COVID-19 as cases of the virus are on the rise in these locations.

Singapore was cited for a having a “very high” level COVID-19 risk by the CDC, which suggests that travelers avoid the country. If a person must travel there, the CDC says they should make sure they are fully vaccinated because they “may be at risk for getting and spreading COVID-19 variants.”

The Level 4 warning -- the CDC's highest risk level -- comes on the heels of Singapore easing its quarantine mandate for vaccinated travelers from the U.S. As of Tuesday, U.S. travelers can enter Singapore with proof of vaccination and a negative PCR test taken 48 hours before departure and upon arrival.

Singapore has had a record level of COVID cases in the last 28 days of 70,374, with just over 82% of residents fully vaccinated, according to data from Johns Hopkins University. A total of 57% of the U.S. population is fully vaccinated, according to the CDC.

Also deemed high risk for travel by the CDC were Angola, Djibouti, Hungary, Cyprus, Eswatini, and Tunisia. These countries were marked Level 3 or “high” risk for COVID-19.

Angola, Djibouti, and Hungary moved up from a Level 2 category, signifying there was a greater risk for contracting or spreading the virus if visiting these nations, while Cyprus, Eswatini, and Tunisia moved down from Level 4, signaling their COVID risk has decreased in these locations.

However, several other countries continue to remain at a Level 4 “very high” level for COVID-19 risk. These countries include popular destinations such as Austria, Belize, Botswana, Croatia, Greece, Ireland, Malaysia, Switzerland, Turkey, and the U.K.

The CDC updates its travel notices weekly and does recommend avoiding international travel until fully vaccinated.
