DRC Bundibugyo outbreak, one month on — is it slowing?
Status as of 6 October 2026, from WHO's Disease Outbreak News. A follow-up to my 18 September brief on the same outbreak. Every number carries its date, because this is a snapshot and it is already old.
The short answer
No single answer. Nationally, the outbreak in the Democratic Republic of the Congo is still growing, slowly: over the last three completed epidemiological weeks, new weekly confirmed cases rose 2.5%, from 475 to 487, and weekly deaths were essentially flat, 224 then 222. That national line hides the map. In some health zones there are clear signs the epidemic is slowing; in others it is still growing. Slowing is a local claim here, not a national one.
Uganda's outbreak is over. Kenya's has just started, with one imported case, and that patient died.
What the record shows
- DRC: 8,728 confirmed cases and 4,205 confirmed deaths as of 6 October 2026, a crude case fatality ratio of 48.2%. (WHO, Disease Outbreak News, 2026-DON619.)
- Spread: 64 health zones across 7 of the country's 26 provinces (Bas-Uele, Haut-Uele, Ituri, North Kivu, South Kivu, Sud Ubangi, Tshopo). Since the previous update on 25 September, the outbreak reached one more zone, Alimbongo, in North Kivu. (Same source.)
- Where people are dying: of the 372 deaths reported since the previous update, 264 happened in the community and 108 in treatment centres. (Same source.) That ratio is the story. It points to late detection and late care, not to a virus that changed.
- Uganda: WHO and Africa CDC declared the outbreak over on 27 August 2026, after 42 consecutive days with no new confirmed case since the last patient, an imported case, was discharged on 16 July 2026. (WHO Regional Office for Africa.)
- Kenya: WHO was informed on 5 October 2026 of a laboratory-confirmed imported case with travel history from the DRC, travelling through Uganda. The patient died. Contact tracing began in Kenya and Uganda. (WHO DON 2026-DON619.)
- Europe: on 1 October 2026 the Netherlands reported the medical evacuation of a healthcare worker who had tested positive for Bundibugyo virus. (Same source.)
Where the check ends
- The figures are a snapshot dated 6 October 2026. More cases and deaths have certainly been reported since. I could not verify anything after that date.
- I read WHO's outbreak reports and the Africa CDC/WHO statement directly. I did not read the DRC's own national situation reports; WHO's numbers are its summary of them.
- A 48% case fatality ratio is confirmed deaths divided by confirmed cases. It is not the share of infected people who die. Milder or untested cases go uncounted, which inflates the ratio. Do not read it as half of everyone infected dying.
- Where this brief says slowing, I cannot tell you whether that is real interruption of transmission or a reporting lag. WHO does not separate the two.
