The U.S. Centers for Disease Control and Prevention (CDC) has introduced a new health declaration requirement for all international flights to the U.S. because of the Ebola outbreak in the Democratic Republic of the Congo. Under the decision signed on October 22, passengers must declare that they have not been in the Democratic Republic of the Congo during the 21 days before their travel.
The measure applies to international flights departing for the U.S. from 11:59 p.m. U.S. Eastern Time on November 3, 2026. The declaration requirement applies to everyone, including U.S. citizens, Green Card holders and passengers transiting through the U.S. to a third country. Passengers flying from Türkiye to the U.S. will also have to complete the declaration.

Airlines will not allow passengers who have not completed the declaration to board and will retain a copy of each declaration for at least 42 days after the flight arrives in the U.S. The declaration can be submitted on a wet-signed paper form, with a verified digital signature or through the airline’s electronic confirmation checkbox.
The decision is expected to remain in effect until December 18, 2026, and will expire on that date unless it is lifted or extended. Anyone who knowingly provides false information could face fines and imprisonment.
