Ebola Death Toll Passes 5,300 as Bundibugyo Outbreak Spreads from DRC to Kenya and Uganda

The death toll from the Bundibugyo Ebola outbreak in Africa has surpassed 5,300, according to figures released by the Africa Centres for Disease Control and Prevention on 3 November. Of the 5,376 deaths, 5,372 occurred in the Democratic Republic of the Congo, with two each in Kenya and Uganda.

The outbreak, the DRC's 17th and its largest, was declared in mid-May after circulating undetected for months in the northeast. Confirmed cases now exceed 10,400 across the DRC, Uganda and Kenya, producing a case-fatality rate above 50 percent. The virus is the Bundibugyo species, a rarer member of the Ebolavirus genus for which no licensed vaccine or specific treatment currently exists.

Transmission remains concentrated in eastern DRC. Ituri province has recorded the majority of cases, followed by North Kivu. Additional provinces including Haut-Uélé, South Kivu, Tshopo and others have also reported infections. Daily case counts have stayed high, with community deaths and delays in detection continuing to drive spread. As of late October, more than 10,000 confirmed cases had been logged in the DRC alone.

Uganda recorded 20 cases, nearly all linked to people who had travelled from the DRC, before being declared free of the virus in August. Kenya reported its first-ever Ebola cases in October: nine infections and two deaths, beginning with a Kenyan citizen who had lived in the DRC and travelled home via Uganda. Nigeria tested two suspected cases in the northeast; both returned negative. A Swiss woman linked to the embassy in Abuja who had travelled to Uganda was evacuated after testing positive, but further transmission was not reported there.

The outbreak has expanded faster than any previous Ebola event. It surpassed 1,000 confirmed cases within roughly 40 days of the formal response, compared with more than 200 days for the 2018-2020 North Kivu outbreak. The 2014-2016 West Africa epidemic remains the largest on record by total numbers, but the current event is already the second-largest and continues to grow.

Clinical trials of the Ervebo vaccine, effective against the more common Zaire strain, have begun in recent weeks. Health authorities emphasise that the Bundibugyo virus differs enough that existing Zaire tools cannot be assumed to work. Contact tracing, isolation and safe burial practices remain the primary controls. In the DRC, eight provinces have been affected since the start. Border crossings have carried the virus into neighbouring countries on multiple occasions.

The European Centre for Disease Prevention and Control assesses the risk to people living in or travelling to affected areas in the EU/EEA as low, given current information. For the countries already reporting cases, the immediate challenges are sustaining isolation capacity, maintaining contact follow-up (reported at roughly 77 percent in some DRC zones) and preventing further cross-border movement of undetected cases. Africa CDC and national ministries continue to coordinate response teams across the affected provinces.

The absence of a licensed Bundibugyo vaccine leaves the response dependent on classic public-health measures. Treatment centres in places such as Beni and other North Kivu and Ituri locations are operating under pressure from the volume of admissions. Community resistance to isolation and burial protocols has been reported in some areas, contributing to the high proportion of deaths that occur outside health facilities. Those community deaths in turn generate new chains of transmission when funerals are conducted without protective equipment.

International partners, including the World Health Organization, have deployed additional staff and supplies. The speed of the current expansion has already drawn comparisons with the early phase of the 2014 West Africa epidemic, though the geographic setting and the specific virus species differ. Whether the case curve can be bent in the coming weeks will depend on the effectiveness of contact tracing in the eight affected DRC provinces and on the ability of neighbouring countries to detect imported cases before secondary transmission occurs.
