Ebola Outbreak is Low Risk to the USA

The U.S. Centers for Disease Control and Prevention (CDC) today issued Health Alert Network Health Advisory CDCHAN-00524 focused on the 16th outbreak of Ebola virus disease (EVD) in the Democratic Republic of the Congo (DRC).

Currently, no suspected, probable, or confirmed EVD cases related to this EVD outbreak have been reported in the United States or outside of the Bulape and Mweka health zones within the Kasai Province, DRC.

The CDC stated on September 18, 2025, that the risk of spread to the United States is currently considered low.

As a precaution, this Health Advisory summarizes CDC recommendations for U.S. public health departments, clinical laboratories, and healthcare workers about potential EVD case identification, testing, and biosafety considerations in clinical laboratories.

An Ebola vaccine (ERVEBO®) is approved for preventing Zaire Ebola virus disease; it should only be given to patients who meet specific criteria.

Two approved treatments are currently available to treat Ebola virus infection: Inmazeb™ and Ebanga™.

To alert international travelers, on September 8, 2025, the CDC issued a Level 1, Travel Health Notice, for people traveling to the DRC.

The CDC recommends that all travelers to the affected health zones in DRC avoid contact with ill people during travel and monitor themselves for symptoms of EVD while in the outbreak area and for 21 days after leaving.

Travelers who develop symptoms during this time should self-isolate and contact their local health authorities or a healthcare provider.

At this time, the CDC is not recommending additional assessments or monitoring of travelers arriving from the DRC by jurisdictional health departments, unless specified in the existing guidance provided.
