Global cholera cases fell 17%, but DR Congo still accounts for a third of the toll
WHO's latest tally puts the 2026 year-to-date count at 58,740 cases and 732 deaths across 22 countries, down sharply from last year except in conflict-affected states.
The World Health Organization's latest global cholera update, published April 30, reports a year-to-date total of 58,740 cases and 732 deaths across 22 countries since January 1 — and a March that was markedly quieter than the same month a year earlier [s1]. The report covers data through March 29; WHO's monthly cholera bulletins run several weeks behind the period they describe, so the April 30 publication is the most current global count for the disease available this month [s1].
Cholera and acute watery diarrhoea cases fell 17% between February and March 2026, and 56% compared to the same period in 2025, when 36,491 cases were reported across 26 countries in that window [s1]. Deaths fell 10% month-over-month and were down 66% year-over-year [s1]. On the numbers alone, 2026 is shaping up as a lighter cholera year globally than 2025 — but the aggregate figure obscures how unevenly that improvement is distributed.
Where the burden concentrates
Of the 16,198 new cases reported in March across 16 countries, the African Region accounted for 8,614 (a 26% drop from February), the Eastern Mediterranean Region for 7,566, and the South-East Asia Region for a further 18, entirely in Myanmar [s1]. No cases were reported that month from the Region of the Americas, the European Region, or the Western Pacific Region [s1].
Three countries account for the bulk of the year's toll. The Democratic Republic of the Congo alone reported 18,992 cases and 522 deaths between January 1 and March 29 — roughly a third of the global case count and 71% of global deaths concentrated in one country [s1]. Twenty-one of the DRC's 26 provinces have reported cases this year. WHO attributes continued spread in Kinshasa to poor sanitation in affected neighborhoods, and describes ongoing risk along the Congo River toward Equateur and Mai-Ndombe provinces, alongside persistently high transmission in eastern lakeside communities [s1].
Mozambique reported 6,584 cases and 63 deaths for the year through March 29, with March itself showing a 55% case decline from February — WHO links the country's outbreak to a run of heavy rains, flooding, and a cyclone since December, with Nampula, Tete, and Sofala provinces carrying the heaviest recent burden [s1]. South Sudan reported 4,390 cases and 58 deaths for the year, with WHO citing active conflict across Jonglei, Upper Nile, and Unity states as a driver of the population displacement and damaged water infrastructure behind continued transmission [s1].
Outside Africa, Afghanistan reported the largest single-country total in the Eastern Mediterranean Region — 18,943 cases since January 1 — followed by Yemen (3,177) and Pakistan (1,647) [s1].
What the case fatality data suggests
Case fatality ratios varied enormously by country in ways that likely reflect health system access as much as the disease itself. The DRC's year-to-date case fatality ratio was 2.7%; Mozambique's was 1.0%; Afghanistan's, where cases are classified as acute watery diarrhoea and case ascertainment differs, was under 0.1% [s1]. WHO's report cautions that the underlying case and death figures are not directly comparable across countries because of differences in case definitions, reporting systems, and surveillance capacity, and that the World Health Organization's Global Task Force on Cholera Control recommends calculating case fatality using facility deaths alone — a distinction most of the countries in this report do not make in their reporting [s1].
Reading a report about last month
Because WHO's cholera epidemiological updates are compiled roughly a month after the period they describe, this report's "current" picture is already several weeks old by the time it is published, and April's actual case trajectory will not be reflected in a WHO update until late May at the earliest. What the report does establish reliably is the shape of the outbreak through late March: concentrated overwhelmingly in a small number of conflict-affected or climate-disaster-affected countries, trending down globally, and trending down specifically in the countries carrying the largest burden — DRC, Mozambique, and South Sudan all posted double-digit percentage declines in March cases compared with February [s1].
WHO's report attributes the underlying drivers broadly to conflict, mass displacement, and climate-related disasters that degrade water and sanitation infrastructure, rather than to any single epidemiological cause common across the affected countries [s1].

Cholera cases are down a fifth this year. Deaths are up by nearly half
WHO counted 409,222 cases and 4,738 deaths across 31 countries by 17 August. The divergence between the two trends is the finding, and it points at case management, not transmission.
Cholera killed 7,598 people in 2025, in fewer countries than two years before
WHO's year-end tally records 614,828 cases across 33 countries. December brought a decline — and the reported figures are known to be a fraction of the true burden.
Preventive cholera vaccination restarts after three years, on doses from one manufacturer
Global oral cholera vaccine supply has roughly doubled since 2022, enough to release 20 million doses for prevention rather than outbreak response. Nearly all of it comes from a single company.
A review flags acute kidney injury as an under-counted toll of Yemen's cholera crisis
Severe dehydration from diarrhoeal disease and sepsis can shut down the kidneys. In a health system with little dialysis, a review argues this is a preventable driver of death that surveillance is missing.
