Ebola Spreads to 60 Zones in the DRC — the Fastest-Moving Outbreak on Record
The Ebola outbreak in the Democratic Republic of the Congo has spread to two additional health zones — Biena and Manguredjipa in North Kivu province — bringing the total number of affected areas to 60, according to DRC Ministry of Health figures reported on August 28, 2026 Al Jazeera. The outbreak, declared on May 14 as the DRC's 17th Ebola epidemic, has now reached 5,794 confirmed cases and 2,786 deaths across six provinces Al Jazeera.
The overall case fatality rate — the share of confirmed cases that end in death — stands at 48 percent. But the newly affected zones of Biena and Manguredjipa are recording substantially higher mortality, which the Ministry of Health attributes to delayed response efforts. Beni, in North Kivu and one of the hardest-hit areas, has recorded 122 confirmed cases and 87 deaths since the outbreak began in mid-May, yielding a fatality rate approaching 69 percent Al Jazeera.
The outbreak is caused by the Bundibugyo ebolavirus species, for which there is no approved vaccine or treatment. That sets it apart from Zaire ebolavirus outbreaks, where vaccines like rVSV-ZEBOV (marketed as Ervebo) have been deployed. WHO Africa confirmed the Bundibugyo strain at the outbreak's onset, with initial cases clustered in the Mongbwalu and Rwampara health zones of Ituri Province WHO Africa. Ituri has remained the epicentre, accounting for roughly 85 percent of cases and 79 percent of deaths as of late August WHO Africa.
The epidemic's geographic footprint now spans Ituri, North Kivu, Haut-Uélé, Tshopo, South Kivu, and Bas-Uélé DRC Ministry of Health. The most recent Ministry of Health situation report before the August 28 update, covering data through August 19, documented 81 new confirmed cases in a single reporting period: 56 in Ituri, 18 in North Kivu, and 7 in Haut-Uélé, along with 40 confirmed deaths DRC Ministry of Health. The trajectory from the initial declaration on May 14, when 8 of 13 tested samples were positive in Ituri, to nearly 5,800 confirmed cases in under four months places this outbreak in a category the UN Secretary-General described in stark terms on August 27: Antonio Guterres warned that it is the fastest-spreading Ebola epidemic ever recorded and is expanding faster than the containment response Al Jazeera.
Médecins Sans Frontières (MSF) opened a new treatment centre in Beni on August 28 to accelerate case management in that high-mortality area Al Jazeera. The organization has 1,400 staff deployed across the DRC supporting the response and operates treatment centres with a combined capacity of 400 beds. The DRC Ministry of Health reported 1,200 recoveries to date, with 18 new recoveries in a 24-hour window, and contact tracing coverage at 83.4 percent DRC Ministry of Health. Contact tracing means identifying and monitoring everyone who has been near a confirmed case, so they can be isolated quickly if symptoms appear.
The broader context here is an outbreak unfolding in one of the world's most operationally complex environments for epidemic response. Eastern DRC's provinces have long been defined by porous borders, episodic armed conflict, and health infrastructure that was strained before the epidemic began. The six-province geographic spread, combined with the mobility of populations across health zone boundaries, complicates contact tracing and any ring vaccination-style approach — even setting aside the absence of an approved Bundibugyo vaccine. (Ring vaccination means vaccinating a ring of people around each confirmed case to create a buffer against further spread.) The 17.4 percent gap in contact follow-up, while not catastrophic in isolation, takes on greater weight when the outbreak is adding new zones faster than response teams can establish surveillance perimeters in existing ones.
The Bundibugyo species itself presents a distinct clinical and logistical challenge. First identified in 2007 in Uganda's Bundibugyo District, it has been associated with lower overall mortality in some past outbreaks compared to Zaire ebolavirus. Yet the 48 percent case fatality rate in this epidemic falls well within the range associated with severe Ebola disease. Without a licensed vaccine, the response architecture relies entirely on classical public health measures: rapid case identification, isolation, supportive care, contact tracing, and community engagement. The absence of a vaccine removes a critical layer of outbreak control that proved decisive in the 2018–2020 Eastern DRC Zaire outbreak, where ring vaccination with rVSV-ZEBOV helped interrupt transmission chains.
Whether the addition of MSF's Beni treatment centre and the existing 400-bed capacity across the response can keep pace with geographic expansion remains the central operational question. The newly affected zones of Biena and Manguredjipa, with their elevated fatality rates driven by delayed response, show what happens when surveillance and case management cannot reach new transmission chains quickly enough.
