TRT World, citing a Health Ministry update, put the cumulative case count at 10,351, and GBC Ghana reported the toll at 5,026 deaths, a crude fatality rate of roughly half among confirmed cases. The previous worst DR Congo outbreak, from 2018 to 2020, recorded 2,299 deaths.
The strain responsible is Bundibugyo virus, not the Zaire species behind most earlier large outbreaks. Al Jazeera reports that the outbreak was declared on 15 May and that no vaccine or treatment has been approved for this strain. That removes the ring-vaccination tool that helped contain the 2018 to 2020 epidemic. UN News reports that the WHO-backed TUMAINI trials will initially test whether the Evebro vaccine, used against the Zaire strain, protects against the current virus, using a ring-vaccination design.
The geographic picture has widened. TRT World lists eight affected provinces: Haut-Uele, Ituri, North Kivu, South Kivu, Bas-Uele, Tshopo, South Ubangi and North Ubangi. The WHO's weekly situation report for 11 October, published by its African regional office, found that Ituri remains the principal focus but accounts for a declining share of cases, at 73.8 percent, with substantial transmission in North Kivu and Haut-Uele. Cases have also crossed borders. In its 23 October Disease Outbreak News, the WHO said Nigeria reported an imported case on 20 October, the fifth country to detect the virus, while Kenya had also reported imported cases. The US CDC assesses the overall risk to the American public and travellers as low.
Containment is struggling. TRT World reports that only about 12 percent of confirmed cases have been identified among previously known contacts, and that many deaths occur in communities. Responders face unpaid wages and violence: the Associated Press, via PBS, reported a walkout at a treatment centre in Tchomia, Ituri, over four months of unpaid pay, while Al Jazeera reported that assailants killed a nurse responding to a suspected case in Tshopo province. The WHO's Patrick Otim called the 5,000 figure a "very tragic milestone". The AP quotes him as saying the number reflects families and communities devastated by the outbreak.
The outbreak is the second largest Ebola epidemic on record, behind West Africa in 2014 to 2016, and CBC describes it as the fastest-growing. Ebola spreads through contact with bodily fluids rather than through the air, so it lacks the pandemic potential of a respiratory pathogen. Even so, an unvaccinated population, imported cases in Nairobi and Abuja, and fragile health systems in conflict zones leave the question of wider regional spread open.
