The number of African countries under the U.S. government's highest travel advisory has risen to 10, after Uganda was added to Washington's Level 4: Do Not Travel list, according to the latest update from the U.S. Department of State.

In a reminder posted on X on Tuesday, the State Department's TravelGov account reiterated that a Level 4 advisory means Americans should "Do Not Travel" under any circumstances, citing dangerous local conditions or the U.S. government's limited ability to provide emergency assistance.

"We issue Travel Advisories with Levels 1–4. Level 4 means DO NOT TRAVEL," the department said. "These places are dangerous. Do not go for ANY reason."

The latest advisory brings the number of African countries on the list to 10, up from nine earlier this year.
