(CNN) — The US Centers for Disease Control and Prevention added even more destinations on Monday to its ever-growing list of places considered to be a “very high” travel risk for Covid-19.
Joining the Level 4 ranks this week are two island nations on opposite sides of the world: Japan in Asia and Cuba, the largest and most populous island in the Caribbean.
The other new Level 4 nations are also scattered around various parts of the globe.
Armenia is in the mountainous Caucasus region on the far reaches of eastern Europe. The Democratic Republic of the Congo is in the heart of Central Africa while Libya is on the Mediterranean coast of northern Africa. Oman is on the Arabian Peninsula, while Israel is on the Mediterranean shores in the Middle East.
The CDC places a destination at Level 4 when more than 500 cases per 100,000 residents are registered in the past 28 days. The CDC advises travelers to avoid travel to Level 4 countries.
To recap, this week’s additions to Level 4 are:
• Democratic Republic of the Congo
Last week, the Democratic Republic of the Congo was at “moderate” Level 2. Armenia, Cuba, Japan, Libya and Oman had been at Level 3, in the “high” risk category.
Other significant places at Level 4
Other tourist favorites parked on Level 4 even longer include Australia, Canada, France, Peru, Singapore and Spain. The United Kingdom has been there since July 2021.
Ray of hope at Level 3
Cape Town, South Africa, is considered one of the most beautiful urban settings in the world. South Africa moved down to the CDC’s Level 3 on Monday.
The Level 3 category — which applies to destinations that have had between 100 and 500 cases per 100,000 residents in the past 28 days — saw three additions on Monday. They were:
• South Africa
South Africa, where the Omicron variant of the coronavirus was first reported, dropped from Level 4, providing a ray of hope for the coming weeks and months that other places will follow suit.
However, the move to Level 3 meant worsening conditions in populous Bangladesh in South Asia and Montserrat, a small British island in the Caribbean. Both had been at Level 2.
Levels 2, 1 and unknown
Destinations carrying the “Level 2: Covid-19 Moderate” designation have seen 50 to 99 Covid-19 cases per 100,000 residents in the past 28 days. This level saw only one addition on Monday: Pakistan. It previously had been at Level 1.
Currently, there are just five destinations at Level 2, including New Zealand, which has some of the world’s tightest travel restrictions.
To be in “Level 1: Covid-19 Low,” a destination must have fewer than 50 new cases per 100,000 residents over the past 28 days.
No destinations were moved to Level 1 on Monday. There are currently only seven destinations in the category. That includes China, which is hosting the Winter Olympic Games.
Finally, there are destinations for which the CDC has an “unknown” risk because of a lack of information. Usually, but not always, these are small, remote places or places with ongoing warfare or unrest. There were no additions this week.
Tanzania, Cambodia and the Canary Islands are among the more-visited locations currently listed in the unknown category. The CDC advises against travel to these places precisely because the risks are unknown.

On December 30, the CDC increased the risk for cruise ship travel to Level 4 and said it should be avoided, regardless of vaccination status. It remained at Level 4 in the newest update.
Considerations for travel
Transmission rates are important to consider when making travel decisions, but there are other factors to weigh as well, according Dr. Leana Wen, a CNN medical analyst, emergency physician and professor of health policy and management at the George Washington University Milken Institute School of Public Health.
“The transmission rates are one guidepost,” Wen said. “Another is what precautions are required and followed in the place that you’re going and then the third is what are you planning to do once you’re there.
“Are you planning to visit a lot of attractions and go to indoor bars? That’s very different from you’re going somewhere where you’re planning to lie on the beach all day and not interact with anyone else. That’s very different. Those are very different levels of risk.”
Vaccination is the most significant safety factor for travel since unvaccinated travelers are more likely to become ill and transmit Covid-19 to others, Wen said.
She said people should be wearing a high-quality mask — N95, KN95 or KF94 — anytime they’re in crowded indoor settings with people of unknown vaccination status.
Before you travel, it’s also important to consider what you would do if you end up testing positive away from home, Wen said. Where will you stay and how easy will it be to get a test to return home?
