The Bundibugyo virus disease (BVD) outbreak in the Democratic Republic of Congo, which began on May 15, has seen a significant increase in cases and deaths, with 3,802 confirmed cases and 1,707 deaths reported as of August 5, 2026. This marks a crude case fatality ratio (CFR) of 44%. The World Health Organization (WHO) suggests that the actual number of infections could be "at least two to four times" higher than official figures, with estimates ranging from 11,500 to 15,300 infections.
The rising death rate, up from 28.8% at the end of June to 44.1% a month later, is attributed by the WHO to persistent delays in case detection, referral, and access to treatment, alongside a predominance of community deaths. Approximately 60% of recorded Ebola deaths occur in communities rather than treatment centers, increasing the risk of infection for relatives and caretakers. The outbreak has spread to five provinces and 49 health zones, including Ituri, North Kivu, South Kivu, Haut-Uélé, and Tshopo, making it the largest Ebola outbreak ever reported in the DRC.
The response to the outbreak is hampered by several factors, including insecurity, population displacement, cross-border movements, and community mistrust. Despite extensive efforts by national authorities, the WHO, and partners, a substantial scaling up of response activities is needed. Only about 15% of 1,170 assessed health facilities have functional triage units, and shortages of protective equipment have led to 134 frontline health worker infections and 40 deaths. UN officials warn that the response needs to expand three- to five-fold to prevent the outbreak from spreading further across borders.
The Bundibugyo strain of Ebola has no approved vaccines or treatments, making early detection and supportive care crucial. The outbreak is unfolding in a region already stressed by years of conflict and severe food insecurity, with 10 million people acutely food insecure. Funding shortfalls have forced the World Food Programme to cut food assistance from 3 million to 1.3 million people, further complicating humanitarian efforts. The UN's broader $2.1 billion humanitarian appeal for Congo is only 45% funded.
