DRC battles Ebola outbreak with no known vaccine as deaths rise

Health authorities in the Democratic Republic of Congo were racing to contain an Ebola outbreak in northeastern Ituri Province as deaths climbed and officials warned the strain has no known vaccine tailored to it. The outbreak was confirmed as Ebola Bundibugyo, a variant first identified in Uganda in 2007, and Congo’s health minister, Samuel-Roger Kamba Mulamba, said it carried a very high lethality rate and had no strain-specific vaccine or specific treatment.

Africa Centers for Disease Control and Prevention said the outbreak had reached 246 suspected cases and at least 65 deaths when it was first reported on May 15, 2026. By May 16, the death toll had risen to 87, reflecting the speed at which the virus was moving through a region that remains difficult to monitor and isolate. The World Health Organization said it was rapidly scaling up support to the Congolese government after the outbreak was confirmed.

The latest flare-up has drawn urgent concern because Ituri borders Uganda and South Sudan, and cross-border movement in the area creates more chances for the virus to move before health workers can trace contacts. Uganda has already reported an imported case involving a Congolese man who died in Kampala from Ebola Bundibugyo, underscoring how quickly the outbreak can spill beyond Congo’s borders.

Samples tested in eastern Ituri confirmed infections in Bunia, Mongwalu and Rwampara, placing pressure on a health system that has limited resources for surveillance, isolation and treatment. Officials have intensified screening, contact tracing and regional coordination, but those tools are harder to deploy in remote areas where roads are poor, reporting is slow and patients can reach clinics only after infecting family members or caregivers.

The outbreak is Congo’s 17th recorded Ebola episode since the virus was first identified in 1976, a reminder that repeated flare-ups have not been eliminated even after decades of experience. What makes this one especially dangerous is the absence of a strain-specific vaccine, which removes one of the most effective tools used in previous Ebola responses and leaves containment dependent on fast detection, isolation and public-health coordination across a volatile border region.
