Multi-country outbreak of cholera, external situation report #26 -22 May 2025
Full report:
Overview
From 1 January 2025 to 27 April 2025, a cumulative total of 157 035 cholera cases and 2148 deaths were reported from 26 countries across three WHO regions, with the African Region recording the highest numbers, followed by the Eastern Mediterranean Region, and the South-East Asia Region. In April 2025 (epidemiological weeks 14 to 17), a total of 37 147 new cholera and/or acute watery diarrhoea cases were reported from 18 countries, territories, areas across three WHO regions, showing a 5% increase from March. The period also saw 561 cholera-related deaths globally, highlighting a 3% decrease from the previous month.
As of 19 May, the stockpile of Oral Cholera Vaccine stands at 3.6 million doses – below the minimum emergency threshold of five million. Persistent global demand continues to exceed supply, undermining efforts to contain cholera outbreaks, ensure rapid response, and conduct preventative campaigns.
Conflict, mass displacement, disasters from natural hazards, and climate change have intensified outbreaks, particularly in rural and flood-affected areas, where poor infrastructure and limited healthcare access delay treatment. These cross-border factors have made cholera outbreaks increasingly complex and harder to control.
