Bundibugyo Ebola Outbreak in the DRC and Uganda: Recoveries, New Treatment Center, and WHO Response
6/1/2026, 12:04:52 AM
Outbreak Overview and International Concern
The Bundibugyo strain of Ebola persists in the Democratic Republic of Congo (DRC) and Uganda. Declared on 15 May 2026, the outbreak lacks approved vaccines or therapies. On 31 May, WHO Director-General Tedros Adhanom Ghebreyesus opened a treatment center in Bunia, Ituri, discharging five patients after supportive care. Brazil placed two suspected patients under isolation, deeming spread risk low.
Case Numbers and Data Discrepancies
WHO reports 906 suspected cases with 223 deaths; Africa CDC cites over 1,000 cases and nearly 250 deaths. Confirmed infections also differ: WHO lists 134 cases and 18 deaths in DRC and Uganda, while Africa CDC reports 263 cases and 43 deaths, with Uganda confirming nine cases and one death.
WHO Priorities for Experimental Treatments and Vaccines
On 28 May, WHO prioritized three therapies for Bundibugyo Ebola—Mapp Biopharmaceutical’s MBP134, Regeneron’s maftivimab, and Gilead’s remdesivir—and recommended Gilead’s oral antiviral obeldesivir. Vaccine candidates include rVSV Bundibugyo from International AIDS Vaccine Initiative and ChAdOx1 Bundibugyo from Oxford University and Serum Institute of India. Merck’s Ervebo is not advised for general use.
Official Statements and Local Leadership
Tedros emphasized care at health facilities to stop transmission. Pierre Akilimali, incident manager at Congo’s National Institute of Public Health, said treatment is helping patients recover. Davin Ambitapio noted the virus is less complex than strains and can help control outbreak. Brazilian officials said spread risk to South America remains low.
Criticism, Community Resistance, and Security Challenges
Doctors Without Borders called for faster testing, aid deployment, and supplies. Residents have attacked health centers over burial restrictions, and armed groups the Allied Democratic Forces and M23 rebels have hindered response, endangering health workers.

Conflicting Reports and Gaps
The differing case counts from WHO and Africa CDC highlight surveillance gaps, and no efficacy data exist for the experimental treatments or vaccine candidates, leaving trial timelines uncertain.
What’s Next: Trials and Expanded Response
WHO plans rVSV Bundibugyo trials in seven to nine months and ChAdOx1 Bundibugyo trials in two to three months, pending animal data. Ongoing community engagement, expanded testing, and health-worker protection remain priorities.
