The Centers for Disease Control and Prevention will require every passenger on international flights to the United States to sign a declaration that they have not been in the Democratic Republic of the Congo in the 21 days before travel, in response to the Ebola outbreak there. The order was signed on Oct. 22.
The requirement takes effect for flights departing for the U.S. at or after 11:59 p.m. EST on Nov. 3. It applies to U.S. citizens, permanent residents and passengers transiting through the United States to a third country, which means Turkish Americans returning from Türkiye will also need to complete it.

Airlines must deny boarding to anyone who has not completed the declaration and keep copies for at least 42 days after the flight arrives. Passengers can sign a paper form, use an authenticated digital signature or check an electronic box offered by the airline.
The order is set to expire on Dec. 18 unless it is rescinded, modified or extended. Knowingly providing false information can lead to criminal fines and imprisonment, according to the CDC.
