Congo’s Bundibugyo outbreak passes 3,000 deaths and 6,186 confirmed cases

The Democratic Republic of Congo’s health ministry counted 3,007 deaths and 6,186 confirmed cases of Ebola on Wednesday, 2 September. The numbers make this outbreak the deadliest in Congo’s history, larger than the 2018–2020 Kivu wave, and the second-largest on record after the 2014–2016 West African epidemic that killed more than 11,000 people in Guinea, Liberia and Sierra Leone.

The pathogen is Bundibugyo ebolavirus, not the Zaire strain that existing licensed vaccines were built to stop. No approved shot or specific drug exists for Bundibugyo. Candidates from the University of Oxford and the International AIDS Vaccine Initiative are in development. A separate vaccination effort using available stock has begun among health workers in Kisangani, Tshopo province, which had logged 19 cases when that campaign started. Officials want a ring around Ituri, the province where the outbreak was declared on 15 May. Some clinicians think transmission began as early as January.

The World Health Organization says about 60 percent of deaths happen outside treatment centres. People die at home, are buried by family, and the chain continues. Africa CDC has said the true case count could be three times the official file because contact tracing is thin. Schools reopened in the middle of the wave. Jean-Claude Angwanzia left Mambasa, in the Ituri epicentre, for Bunia because he did not feel safe. Those are the human facts under the spreadsheet.

Congo has fought Ebola before and won. This time the species, the speed and the geography are worse. Ituri and the northeast already host other armed conflicts. Cold-chain, safe burial teams and laboratory turnaround compete with roads that close and clinics that empty when a town hears the word Ebola. The 2014–16 West African outbreak became a regional event because those same systems failed early. WHO has already said this wave is on a path that could pass that death toll if the slope does not break.

Fifty thousand doses of a vaccine product have arrived for health workers. That is a start for the people who draw blood and wash bodies. It is not a population campaign. Until a Bundibugyo-specific product is shown to work, the tools are isolation, contact lists, safe funerals and the hope that a ring around Ituri holds. The ministry’s own chart says it has not held so far.

The comparison that matters for planners is not 2018. It is 2014. Case counts in the low six thousands with a 48 percent case-fatality ratio among confirmed patients, most deaths outside wards, and a virus with no licensed shot: that is the file as of 2 September. Every week the file grows, the chance of export to a neighbouring province or country grows with it.
