Key takeaways
- 550 laboratory-confirmed cases reported across DRC and Uganda with 18.4% case fatality ratio
- Geographic spread accelerating with 25 health zones now affected across three provinces
- Ituri Province bears 94.2% of cases with intense community transmission ongoing
Outbreak Intensifies Across Multiple Provinces
The World Health Organization reports that intense community transmission continues in the Democratic Republic of the Congo, with geographic spread increasing rapidly. Since May 31, 2026, health authorities have documented 229 new confirmed cases, including 53 new confirmed deaths across the affected regions.
The outbreak has now spread to 25 health zones across three provinces: 17 of 36 health zones in Ituri Province, seven of 34 in North Kivu Province, and one of 34 in South Kivu Province.

Ituri Province Bears Heaviest Disease Burden
Ituri Province remains the epicenter of the outbreak, accounting for 518 confirmed cases (94.2%) and 80 confirmed deaths (79.2%) of the total burden. The most severely affected health zones within Ituri include Bunia with 152 cases and 15 deaths, Rwampara with 111 cases and 20 deaths, and Mongbwalu with 98 cases and 29 deaths.
These four health zones collectively represent 70.4% of all cases and 64.4% of all deaths reported across the Democratic Republic of the Congo, according to the WHO epidemiological data. However, health zone information remains missing for 94 confirmed cases, including 10 deaths in Ituri Province.

Cross-Border Transmission Patterns Emerge
The outbreak’s cross-border nature presents significant public health challenges for regional containment efforts. WHO surveillance systems continue monitoring transmission patterns between the Democratic Republic of the Congo and Uganda.
The high case fatality ratio observed in North Kivu Province at 60.0% significantly exceeds the overall outbreak CFR of 18.4%, suggesting potential delays in case detection and treatment access in certain geographic areas. Public health response efforts focus on strengthening surveillance and treatment capacity across affected health zones.
What this means
Frequently asked questions
What is Bundibugyo virus disease?
Bundibugyo virus disease is a severe viral hemorrhagic fever caused by one of six known ebolaviruses. It was first identified in Uganda’s Bundibugyo district in 2007 and typically has lower case fatality rates than Ebola virus disease.
How does the current outbreak compare to previous Ebola outbreaks?
The current outbreak shows rapid geographic spread across multiple provinces but maintains a relatively moderate case fatality ratio of 18.4% compared to historical Ebola virus disease outbreaks. The cross-border transmission pattern requires coordinated regional response efforts.
What prevention measures are most effective?
Key prevention measures include avoiding contact with infected individuals or contaminated materials, practicing proper hand hygiene, and seeking immediate medical care for symptoms. Healthcare workers should follow strict infection prevention protocols including personal protective equipment use.
The WHO continues coordinating international response efforts with national health authorities to contain the outbreak and prevent further geographic spread. Enhanced surveillance systems and community engagement remain critical components of the ongoing public health response across affected regions.
