WHO: DRC Bundibugyo Ebola at 7,890 cases / 3,799 dead — new province + South Sudan border zone
The World Health Organization’s Disease Outbreak News of 25 September 2026 stamps the Bundibugyo virus disease outbreak in the Democratic Republic of the Congo at 7,890 confirmed cases and 3,799 deaths as of 23 September — a crude case fatality ratio of 48.1% — and says the epidemic has expanded since the 11 September DON into two more health zones, including Bulu in a new province (Sud Ubangi) and Dungu in Haut-Uélé on the South Sudan border, raising cross-border transmission risk.
Key facts
- DON618 count (as of 23 Sep)
- 7,890 confirmed cases · 3,799 deaths · crude CFR 48.1% · 1,966 recovered
- Since the 11 Sep DON
- +1,133 confirmed cases · +532 confirmed deaths
- New health zones
- Bulu, in Sud Ubangi — a new province for this outbreak, north-west DRC · Dungu, in Haut-Uélé, bordering South Sudan
- Footprint
- 63 health zones across seven of 26 provinces: Bas-Uélé, Haut-Uélé, Ituri, North Kivu, South Kivu, Sud Ubangi, Tshopo · 48 zones in six provinces reported at least one case in the last 21 days
- Epicentre
- Ituri remains the most affected province — 28 of its 36 health zones reporting cases
- Cross-border (WHO)
- The latest geographic expansion increases the risk of cross-border transmission
- Trend (WHO)
- National daily new-case count remains high; transmission intensity varies sharply by province and health zone
- Mortality signal (WHO)
- Continuously high CFR and a high rate of deaths in communities point to delays in case detection and access to early care
- Scale (WHO)
- Second documented Bundibugyo outbreak in the DRC after 2012; the largest Ebola disease outbreak ever recorded in the DRC irrespective of Ebola virus species
- Delta vs boarded Sep 2 card
- ~3,000 deaths (WHO DG briefing, 2 Sep) → 3,799 deaths among 7,890 confirmed cases (DON618, as of 23 Sep)
- Supersedes
- The Sep 2 ~3,000-death card — off the board; its page and the Aug 28 DON616 card stay live in the archive
- Live later
- Next WHO DON / DRC Ministry of Health count · any confirmed South Sudan or cross-border case · Ervebo expanded-use or trial readouts → fracture HUD — no invented export case or death toll

Note
The World Health Organization’s September 25 Disease Outbreak News puts hard numbers back on the Bundibugyo Ebola board in the Democratic Republic of the Congo. As of September 23: 7,890 confirmed cases, 3,799 deaths, a crude case fatality ratio of 48.1%, and 1,966 recovered. Since the previous DON on September 11, WHO counts 1,133 more confirmed cases and 532 more confirmed deaths.
The outbreak has entered two more health zones — Bulu in Sud Ubangi, a new province for this epidemic, and Dungu in Haut-Uélé on the South Sudan border. That brings the footprint to 63 health zones across seven provinces; 48 zones in six provinces reported at least one case in the last 21 days. Ituri remains the hardest-hit province. WHO says the new geography raises cross-border transmission risk, flags the still-high rate of deaths in communities as a detection and care-access failure, and again calls this the largest Ebola disease outbreak ever recorded in the DRC regardless of virus species.
This supersedes the September 2 ~3,000-death card as the live Ebola stamp; that page and the August DON616 card stay live in the archive. Any confirmed South Sudan case and the next WHO count go to the HUD.
Why it matters
Nearly thirty-eight hundred dead on the official stamp, a new province on the zone list, and a border district facing South Sudan. WHO’s own product calls it the largest Ebola outbreak the Congo has ever recorded. Official count and geography — not a claim that the virus has already crossed.
