DRC Faces Fastest-Growing Ebola Outbreak in History with 3,605 Cases

DRC Confronts Largest and Fastest-Growing Ebola Outbreak in History

As of July 30, 2026, health authorities reported a total of 3,605 confirmed cases and 1,587 deaths, corresponding to a crude case fatality ratio of 44 percent. During the most recent complete reporting week—epidemiological week 30—officials recorded 567 new cases and 296 deaths in a single week, highlighting what the WHO described as an exceptional pace of transmission.

Geographic Spread and Province-Level Impact

Initially confined to the Mongbwalu health zone in Ituri Province, the outbreak has expanded across five provinces—Ituri, North Kivu, South Kivu, Haut-Uélé, and Tshopo—now impacting 49 health zones.

Ituri remains the epicenter of the emergency, accounting for 88 percent of all confirmed cases with 3,176 infections, and 82.6 percent of nationwide deaths with 1,311 fatalities. Within Ituri Province, the highest concentrations of confirmed cases are reported across several key areas:

* Bunia health zone: 880 cases * Rwampara health zone: 627 cases * Mongbwalu health zone: 541 cases * Nizi health zone: 377 cases * Lita health zone: 131 cases * Nyankunde health zone: 114 cases

Prof Pierre Akilimali, who oversees the national public health institute (NPHI) Ebola response, noted that the Bunia and Rwampara health zones alone continue to see between 100 and 150 new confirmed infections each week.

Response Challenges and Mitigation Efforts

Health responses have faced severe operational hurdles. According to Irishtimes, conflict in many affected areas has badly hampered containment efforts. Prof Akilimali explained that local issues including insecurity, mining activities, and high population density make the current emergency significantly more complex than prior outbreaks. Dr Justus Nsio, field incident manager for the Africa Centres for Disease Control and Prevention, added that experts monitoring the situation widely agree the outbreak was detected too late.

To combat the spread, Congolese authorities have implemented targeted measures, constructing more than 20 Ebola treatment centres, establishing local diagnostic laboratories, and strengthening surveillance via community liaison officers.

Additionally, clinical trials for a vaccine against the Bundibugyo strain—for which there is no standard treatment—began in early July. Prof Placide Mbala, head of laboratory operations for the DRC Ebola response, stated that about 20 people had been enrolled in the trials as of July 15, with the evaluation expected to last up to four months.

Regional Context and Cross-Border Collaboration

Neighboring Uganda officially declared the end of its own Bundibugyo virus disease outbreak on July 28, following 42 days without a new locally transmitted case after its final confirmed patient was discharged from care. Despite this milestone, the WHO warned that Uganda remains at risk of imported cases and re-introduction due to ongoing transmission in the DRC and continuous population movement across borders.

In response, Uganda has deployed experts to work directly alongside Congolese counterparts, specifically supporting monitoring and containment operations in border regions such as Tchomia and Kasenyi.
