The United States has issued a Worldwide Caution Health Alert dated May 22, 2026, introducing new arrival restrictions and enhanced Ebola screening measures for travelers bound for the U.S. from select African countries.

Under the new directive, U.S.-bound passengers who have been present in the Democratic Republic of the Congo, Uganda, or South Sudan within 21 days of arrival must enter the United States only through designated airports where enhanced health screening will be carried out.

The designated entry points include Washington Dulles International Airport (IAD) for flights after 11:59 p.m. on May 21, 2026, Hartsfield–Jackson Atlanta International Airport (ATL) for flights after 11:59 p.m. on May 22, 2026, and George Bush Intercontinental Airport (IAH) in Houston for flights departing after 11:59 p.m. on May 26, 2026.

The U.S. Centers for Disease Control and Prevention (CDC) and the Department of Homeland Security (DHS), through Customs and Border Protection (CBP), will implement enhanced public health screening at these airports in response to the ongoing Ebola outbreak. Officials said the measures apply to all passengers, including U.S. citizens, who have recently been in the affected countries.

Authorities have warned that travelers may experience flight disruptions, including delays, cancellations, or rerouting, as airlines adjust to the new requirements. Passengers planning to travel to the United States are advised to confirm their flight details with airlines before departure.

The U.S. government has urged travelers to review updated health guidance, including CDC recommendations for individuals returning from affected regions, and to stay informed through official consular advisories regarding the Ebola outbreak. Travelers are also encouraged to enroll in the Smart Traveler Enrollment Program (STEP) to receive real-time safety and security updates.
