Ebola outbreak in DRC outpacing containment efforts despite some progress

Sep 7, 2026

The 17th Ebola outbreak in the Democratic Republic of the Congo has surpassed 6,271 cases and 3,041 deaths. Despite some progress, including a declining reproduction number, containment efforts are severely faltering. Over 75% of daily deaths occur in the community rather than treatment centers, fueling transmission. Responders face critical gaps, with only 15% to 20% of new cases coming from known contact lists, alongside community resistance and a lack of proven vaccines for the Bundibugyo strain.

Outbreak mortality statistics

▪On August 31, 2026, community deaths accounted for 75.4% of daily Ebola mortality in the Democratic Republic of the Congo, with 43 of 57 confirmed deaths occurring outside treatment centers.
▪The 17th Ebola outbreak in the Democratic Republic of the Congo has caused 3,041 deaths among 6,271 confirmed cases, according to data reported by August 31, 2026.
▪The World Health Organization projected that the Ebola outbreak in the Democratic Republic of the Congo could surpass the 2014-2016 West Africa outbreak, which killed over 11,000 people.

Transmission reproduction numbers

▪The time-varying reproduction number (Rt) for the Ebola outbreak in the Democratic Republic of the Congo averaged 1.00 over the final two weeks of August 2026.
▪The basic reproduction number (R0) for the 2026 Democratic Republic of the Congo Ebola outbreak was estimated at approximately 2.51 by a CDC branching process model in June 2026.

Safe burial team challenges

▪Ebola burial teams in Ituri province, paid $20 a day, report facing extreme physical fatigue and an increasing workload since the outbreak began in mid-May 2026.
▪Fewer than half of the affected health zones in the Democratic Republic of the Congo have active safe and dignified burial teams to handle deceased Ebola victims.

Community resistance to protocols

▪Ebola burial teams in the Democratic Republic of the Congo have faced physical attacks from bereaved families frustrated by the prohibition of traditional African burial rituals.
▪Jeanne Alasha, adviser to the military governor of Ituri, stated that individuals who assault Ebola burial teams are committing offenses punishable by law.

Contact tracing gaps

▪Contact tracing efforts captured only 19.2% of expected contacts over a 21-day period in August 2026, leaving an estimated 78,816 contacts unaccounted for.
▪Only 15% to 20% of new confirmed Ebola cases in the Democratic Republic of the Congo were previously identified as known contacts under active surveillance.

Vaccine deployment efforts

▪There is no conclusive evidence that the Ervebo vaccine, licensed for Zaire ebolavirus, provides protection against the Bundibugyo virus causing the current outbreak.
▪The Democratic Republic of the Congo rolled out 70,000 doses of the Ervebo vaccine to frontline health workers, reserving 20,000 doses for a phase 3 trial.
