WHO: Global Cholera Deaths Rose 30% in 2025 to Their Highest Level Since 1999 — Even as Cases Fell
September 30, 2026. The World Health Organization reports that 7,870 cholera deaths were recorded in 2025 — a 30% rise and the highest annual death toll since 1999 — even as reported cases fell 20% to 451,499 (CIDRAP, Sept 30, 2026; WHO news release, Sept 29, 2026). The divergence points to outbreaks that are deadlier where they do occur: "one in five reported deaths occurred outside healthcare facilities," i.e., people are dying without ever reaching care.
Extreme concentration: just seven countries — Angola, Bangladesh, DRC, Nigeria, South Sudan, Sudan, and Yemen — accounted for 90% of reported cases and deaths, and WHO notes all seven recorded conflict- or disaster-related displacement this year. WHO's Chikwe Ihekweazu: "No one should be dying from cholera today when we have the tools to prevent and treat this disease. The concentration of cases and deaths in a small number of countries shows where targeted investments in safe water, sanitation and hygiene could have the greatest impact."
Same report, other diseases (WHO Weekly Epidemiological Record 101-38): Africa's meningitis belt logged 21,526 bacterial meningitis cases in 2025 (−6% vs 2024) with 971 deaths (CFR 4.5%; deaths down 30% from 1,397). For plague, 2019–2025 saw 3,847 suspected human cases and 423 deaths (CFR 11%), mostly in the DRC and Madagascar.
Why it matters: rising deaths amid falling cases is the signature of collapsing access to treatment in conflict/displacement settings — the same fragile-region pattern driving the DRC Ebola outbreak (Bundibugyo Ebola Reaches Nigeria — WHO Warns of a "More Complex Outbreak Landscape" as the Origin Story Fractures). Cholera's case fatality in untreated patients runs high and fast; the 2025 data suggest the "tools to prevent and treat" are not reaching the seven countries that need them.
