Situation Report: DRC Declares Ebola Zaire Outbreak

The Ministry of Health in the Democratic Republic of Congo (DRC) has declared an outbreak of Ebola Virus Disease (EVD) caused by Zaire ebolavirus, the same strain responsible for the 2014 West African Outbreak. Here’s what frontline healthcare workers should know—and where to turn for trusted NETEC guidance and support.

Outbreak Highlights & Clinical Situation

Confirmed outbreak: As of September 4, 2025, the outbreak has affected Bulape and Mweka health zones in the central province of Kasai, with 28 suspected cases and 15 deaths, including four healthcare workers. The index patient—a 34-year-old pregnant person—was admitted on August 20 with sudden fever, hemorrhage, and fatigue, and died of multiorgan dysfunction syndrome on August 25. Field response teams are en route to the affected zones, including national Rapid Response Teams and WHO experts in epidemiology, infection prevention and control, laboratory, and case management.

Ebola Zaire species: This high-fatality strain was responsible for the 2014 West African outbreak. Unlike then, there are now licensed vaccines (Ervebo) and therapeutic medical counter measures (Inmazeb, Ebanga) available. The DRC has 2,000 vaccine doses prepositioned in Kinshasa to protect contacts and frontline healthcare workers.

Transmission, Symptoms, and Response Essentials

Transmission: Spread occurs through direct contact with bodily fluids—such as blood, vomit, feces, saliva—or contaminated surfaces and instruments.

Symptoms: Include high fever, muscle aches, vomiting, diarrhea, severe dehydration, and hemorrhage, typically emerging 2–21 days post-exposure (median 8–10 days). Once symptoms appear, the patient becomes contagious.

Critical care: Early supportive measures are key. Clinical support—fluid resuscitation, electrolyte balance, and critical care interventions—improves survival. Learn more.

Global & U.S. Threat Level

Threat to U.S. remains low: There are no direct flights connecting Kasai Province with the U.S., and no U.S. government deployments currently in the region. Still, U.S. healthcare workers should stay alert and follow the identify–isolate–inform protocol when evaluating patients with relevant symptoms and travel or exposure history.

Ongoing monitoring: Case counts are likely to rise as transmission continues. NETEC and partners are tracking the outbreak and will provide updates and technical guidance as information becomes available.
