# What happened
Congo (DRC) is facing a rapidly growing Ebola outbreak declared in May. An official situation report dated Aug. 31 recorded 6,186 confirmed cases and 3,007 deaths. A further 1,409 people have recovered, and 830 patients remain in isolation or at Ebola treatment centers.
# Where the virus is concentrated
The outbreak has spread across 60 health zones in six provinces: Ituri, North Kivu, Haut-Uele, Tshopo, South Kivu and Bas-Uele. Ituri is the main hotspot, accounting for 81.9% of confirmed cases nationwide.
# What the UN says
Tom Fletcher, UN under-secretary-general for humanitarian affairs and emergency relief coordinator, warned in an online briefing that the virus is outpacing the scaled-up response. He said an incremental approach is insufficient for an epidemic growing exponentially and that a sustained, large-scale operation is needed.
Fletcher listed concrete needs: more treatment capacity, additional teams to manage safe and dignified burials, and better access for humanitarian personnel and supplies. He also noted broader pressures including conflict-driven displacement, acute food insecurity and malnutrition—nearly 11 million people in the DRC already require humanitarian assistance.
# Risks to responders and operations
More than 40 health workers have died while responding to the outbreak. Treatment centers and ambulances have been attacked, complicating care delivery and limiting safe patient transport and outreach.
# Vaccination and guidance
Ervebo vaccine, which the World Health Organization prequalified in 2019 for prevention of disease caused by Zaire ebolavirus. The WHO issued updated emergency guidance on Ervebo's use. The WHO emphasized that vaccination must not replace established outbreak-control measures such as surveillance, rapid diagnosis, isolation and clinical care, infection prevention and control, contact tracing, and safe burials.
Provision approved an initial release of 70,000 Ervebo doses at the DRC government's request. The allocation is split into 20,000 doses for a Phase 3 clinical trial to assess the vaccine's impact against the Bundibugyo virus, and 50,000 doses intended for frontline and health workers.
# How this outbreak ranks
Since its declaration in May, the outbreak has become the DRC's largest and deadliest Ebola epidemic on record and is the second-largest Ebola outbreak globally, behind the 2014–2016 West Africa epidemic.
# What this means for response planning
# Immediate implications for readers tracking the situation
Expect numbers and geographic spread to change as surveillance and reporting continue. Key indicators to watch are case counts by province (especially Ituri), capacity and security at treatment centers, the pace of vaccination and trial enrollment, and humanitarian access for teams delivering medical and non-medical assistance.
