(The hill) – The Centers for Disease Control and Prevention (CDC) on Tuesday added 22 countries to its anti-travel advisory list.
The countries were added to the highest level four warning due to rising levels of COVID-19.
Some of the countries added include Israel, Australia, Egypt, Albania, Argentina, Uruguay, Panama, Qatar, Bahamas, Bahrain, Bermuda, British Virgin Islands, Turkish Islands and Caicos, Suriname, Saint Lucia and Bolivia, Reuters reported.
The Tier Four classification now has more than 100 countries as nations struggle to combat the highly contagious omicron variant.
The CDC advises to avoid tier four countries at all costs and to fully vaccinate a person if they must travel there.
Fewer than 20 countries are at the CDC’s lowest alert level of Level 1.
In recent weeks, popular travel destinations for Americans like Canada and Aruba have moved to the highest warnings due to rising COVID-19 cases.
Many countries halted travel from several African countries after the discovery of the omicron variant to slow the spread of the virus, but the coronavirus still spread rapidly around the world.
