The US Centers for Disease Control and Prevention has moved two South American destinations, one Middle Eastern country and a North African nation to its "high" risk category for travel.

Four destinations were moved to Level 3, or "high" risk on Monday:

Peru, known for its capital city's culinary excellence and remarkable Inca ruins in the Andes, was previously listed at Level 2, "moderate" risk. Bolivia, Lebanon and Tunisia were also listed at Level 2 last week.

Level 3, or "high," is now the top rung in terms of risk level and applies to places that have had more than 100 cases per 100,000 residents in the past 28 days. Level 2 and Level 1 are considered "moderate" and "low" risk, respectively.

There were about 115 destinations at Level 3 on July 11. Level 3 locations account for nearly 50% of the roughly 235 places monitored by the CDC.

Level 4, previously the highest risk category, is now reserved only for special circumstances, such as extremely high case counts, emergence of a new variant of concern or health care infrastructure collapse. Under the new system, no destinations have been placed at Level 4 so far.

Much of Europe has been stubbornly lodged at Level 3 for months with the summer travel season in full swing. As of July 11, the following popular European destinations were among those remaining at Level 3:

Those aren't the only high-profile spots that find themselves at Level 3. Numerous other destinations around the world are among those in the "high" risk category, including the following:

Destinations carrying the "Level 2: Covid-19 Moderate" designation reported 50 to 100 Covid-19 cases per 100,000 residents in the past 28 days. The CDC moved just one place to this level on Monday: Fiji.

Fiji moved up from the Level 1, "low" risk category.

There are 16 places in the "moderate" risk category this week.

To be listed as "Level 1: Covid-19 Low," a destination must have had 49 or fewer new cases per 100,000 residents over the past 28 days. Just one place was added to the category on July 11: Romania.

The move to Level 1 is good news for Romania, which was listed in Level 2 last week.

There are more than 40 places in the "low" risk category this week.

A few of the more popular places in the "low" risk category this week include Indonesia, India and the Philippines.

Finally, there are the destinations the CDC has deemed to be of "unknown" risk because of a lack of information. Usually, but not always, these are small, remote places or places with ongoing warfare or unrest. Four places were added to this category this week:

Armenia and Liberia were previously listed at Level 1. Laos and Mongolia were listed at Level 3.

The CDC advises against travel to these places precisely because the risks are unknown. Other destinations in this category that typically draw more tourist attention include French Polynesia, Macau and the Maldives.

Transmission rates are just "one guidepost" for travelers' personal risk calculations, according to CNN Medical Analyst Dr. Leana Wen.

We've moved into "a phase in the pandemic where people need to make their own decisions based on their medical circumstances as well as their risk tolerance when it comes to contracting Covid-19," said Wen, who is an emergency physician and professor of health policy and management at the George Washington University Milken Institute School of Public Health.

There are other factors to weigh in addition to transmission rates, according to Wen.

"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," she said.

"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.

And it's also important to consider what you would do if you end up testing positive away from home.
