Cholera remains a standing global health threat rather than a single outbreak. The most recent WHO global Disease Outbreak News available in this session said that between 2025-01-01 and 2025-08-17, 409,222 cholera or acute watery diarrhoea cases and 4,738 deaths were reported from 31 countries, and WHO assessed the risk of further spread within and between countries as very high. WHO also warned that underreporting, different case definitions, conflict, displacement, weak water and sanitation systems, and oral cholera vaccine constraints are complicating control. In the last 7 days, the movement seen here is mainly through media and outbreak-tracker reports rather than a fresh WHO global update. Zambia publicly declared an outbreak, but reports disagree on the classification of the same headline total: one report says 304 suspected cases, 62 confirmed cases, and 11 deaths, while another says 304 confirmed cases and 11 deaths. A Bangladesh editorial reported more than 1,200 hospitalisations linked to a Dhaka outbreak at icddr,b. WHO’s Angola country office reported that Angola has passed 43,000 cases and 1,000 deaths since January 2025. A Nature news feature highlighted concern about multidrug-resistant cholera in Kenya and the role of climate extremes and environmental persistence. What to watch now is whether WHO publishes a new global update for late 2025 or 2026, whether Zambia’s outbreak spreads across borders or urban centres, whether Bangladesh releases an official national count, and whether antimicrobial resistance signals in East Africa begin to affect treatment guidance or outcomes.
Situation as of 6 Oct 2026
Official
WHO’s latest global position available in this session remains that cholera is a multi-country emergency with very high risk of further spread. In its 2025 multi-country update, WHO said 409,222 cholera/AWD cases and 4,738 deaths had been reported from 31 countries between 2025-01-01 and 2025-08-17, with outbreaks escalating across multiple countries and underestimation likely because of reporting differences and incomplete surveillance. WHO’s Angola country office separately reported on 2026-09-30 that Angola had recorded over 43,000 cases and more than 1,000 deaths since the start of 2025.
Media, unverified
Recent press and outbreak-tracker items point to continuing activity in several settings. Zambia’s outbreak declaration was widely reported at the end of September and early October. Bangladesh press reported heavy hospital burden in Dhaka, with more than 1,200 hospitalisations cited at icddr,b. A Nature news feature focused on Kenya’s multidrug-resistant cholera threat and the need for environmental genomic surveillance, presenting antimicrobial resistance as an emerging concern rather than announcing a new national case total.
Control measures
The main control measures described by WHO are strengthened surveillance and laboratory confirmation, rapid response teams, case management with ORS and IV fluids, WASH interventions, infection prevention and control, community engagement, cross-border coordination, and oral cholera vaccination campaigns where available. In Angola, WHO described training health workers, deploying rapid response teams, community outreach, water-treatment support, and vaccination efforts. Media reporting from Zambia indicates formal outbreak declaration and active treatment of current patients.

- · Another Zambia report on the government declaration gave a different interpretation of the same headline total, saying 304 cases and 11 deaths had been recorded across seven districts.
- · A Bangladesh editorial said Dhaka’s cholera outbreak had led to more than 1,200 hospitalisations at icddr,b, framing the event as a serious urban water-and-sanitation failure.
- · A Zambia outbreak report said the government had declared cholera with 304 suspected cases, 62 laboratory-confirmed cases, and 11 deaths across seven districts in five provinces; Lusaka Province was described as the most affected.
- · Nature reported growing concern about multidrug-resistant cholera in Kenya, linking climate extremes, environmental persistence, and the case for environmental genomic surveillance.
