Global Cholera Resurgence in 2026
Recent Developments
012026-06-30: WHO reported 29,610 new cholera and AWD cases and 271 deaths in May 2026 across 16 countries/territories/areas, with a 43% month-on-month rise in cases and a 30% rise in deaths.
022026-06-22: ECDC reported 105,813 global cholera cases and 1,216 deaths since 1 January 2026, with Nigeria and DRC reporting the largest case burdens.
032026-03-29: WHO reported 58,740 cumulative cases and 732 deaths from 1 January to 29 March 2026 across 22 countries, with Africa accounting for the largest share of cases and deaths.
Interventions
- WHO global surveillance and multi-country outbreak coordination for cholera and AWD monitoring across affected regions.
- Targeted oral cholera vaccine (OCV) use for high-risk settings, including emergency and relief contexts, as reflected in ECDC guidance for higher-risk travelers and response settings.
- Case management, WASH restoration, and outbreak control measures in affected countries are the primary ongoing response pillars described across surveillance updates.
What Works
- Rapid treatment and rehydration reduce cholera mortality substantially; ECDC notes cholera CFR is below 1% when treated, versus 25–50% without treatment.
- Oral cholera vaccination is an evidence-based prevention tool used in outbreak response and high-risk settings.
- Improving safe water, sanitation, and hygiene access is essential to interrupting transmission, especially in conflict- and flood-affected areas repeatedly cited by WHO and ECDC.
How to Help
- Support organizations responding to cholera outbreaks, including humanitarian medical and WASH responders working in affected countries.
- Donate to emergency health and water-sanitation response funds that support cholera treatment, vaccination, and clean water access.
- Advocate for increased funding for cholera control, WASH infrastructure, and humanitarian access in conflict-affected settings.

WaterAid tackles cholera by addressing the underlying WASH drivers of outbreaks: unsafe water, poor sanitation, and limited hygiene infrastructure. Its approach includes building and improving water systems, sanitation facilities, and hygiene services in vulnerable communities, which directly reduces fecal-oral transmission and helps prevent recurrent outbreaks.
GTFCC released new recommendations in April 2025 for redesigning cholera surveillance systems to enable smarter outbreak control and early detection, developed by epidemiologists from over 50 organizations; they monitor global cholera trends, issue situation reports, advocate for increased investments in WASH and vaccines, and support national cholera control plans in affected countries.
WHO’s contribution in Gaza is through health-system support and public-health response to the consequences of unsafe water and fuel shortages, including preventing and managing outbreaks linked to poor water and sanitation conditions. In practice, WHO works through emergency health coordination and support to essential service continuity rather than direct water delivery.
The Carter Center works on Tanzania through election-related observation and democracy support. In a post-election crackdown environment, its approach is to assess the integrity of elections, document irregularities, and publish findings that can inform reforms and reduce the likelihood of election-related violence that disrupts schools, universities, and broader public services.
