The US Centers for Disease Control and Prevention (CDC) has implemented a mandatory health screening requirement for all individuals arriving in the United States by air. Effective since November 3, 2026, every passenger—including US citizens, permanent residents, and flight crew—must provide a formal attestation confirming they have not spent time in the Democratic Republic of the Congo (DRC) within the 21 days prior to their departure. This policy applies to all international flights, including those transiting through the US, and is designed as a precautionary public health measure to mitigate the risk of Ebola transmission.

To comply with these regulations, travelers are required to download, print, and sign an attestation form from the official US government website and present a physical copy during the check-in process or at the boarding gate. Airlines are now tasked with verifying that every passenger or their authorized representative has completed this paperwork, and they must maintain these records to be produced upon request by federal authorities. While the CDC emphasizes that the overall risk to the American public remains low, the mandate ensures that all air carriers operating flights to the US maintain strict oversight regarding potential exposure to the DRC.
