Nearly 17,000 new cases of cholera and acute watery diarrhoea were reported across 19 countries in January 2026, according to data released by the World Health Organization. The figures, representing epidemiological weeks 1 to 4 of the year, show a slight 6% decrease compared to December 2025, but as well a concerning 20% rise in fatalities, reaching 182 deaths globally.
The African Region continues to bear the brunt of the outbreak, accounting for the highest number of reported cases. The Eastern Mediterranean and South-East Asia Regions are also significantly affected. Notably, no cases were reported in the Western Pacific or the Americas during the reporting period.
The surge in cases is occurring against a backdrop of a broader cholera upsurge that began in 2021, prompting increased concern from global health organizations. A recent geographical shift in the burden of the disease within Africa is complicating control efforts, according to research published in Nature.
Unicef has warned that approximately 80,000 children are at high risk of contracting cholera as outbreaks spread across 12 countries in West and Central Africa. The organization is working to provide assistance, but the scale of the crisis is straining resources.
The WHO released its 31st external situation report on the multi-country outbreak on October 29, 2025, indicating the ongoing nature of the crisis and the continued need for vigilance and coordinated response. The report details the evolving situation and outlines ongoing efforts to contain the spread of the disease.
CIDRAP reports that surges in Africa are driving a worsening cholera situation, and the WHO continues to monitor the situation closely. The organization has not yet issued a statement regarding the January 2026 data, and its next report is scheduled for release in March.
