The U.S. State Department has issued a health alert, effective May 21, 2026, requiring US citizens and lawful permanent residents who have within 21 days of their planned arrival to the U.S. been present in any of Uganda, South Sudan, or the Democratic Republic of Congo to enter only through Washington Dulles International Airport (IAD) for enhanced public health screening.
This restriction is in addition to the CDC’s order of May 18 of a 30-day suspension of entry for any foreign national who has been in these countries in the past 21 days.
