More than 3,000 people have died from cholera worldwide in 2026. The World Health Organisation (WHO) says Africa accounts for nearly 90 per cent of the deaths. Despite a drop in fatalities compared with 2025, the disease remains a major health concern. Poor sanitation and unsafe drinking water continue to put lives at risk.
WHO reports that cholera killed nearly 7,900 people across 47 countries in 2025. This was the highest death toll since 1999. The organisation also recorded 451,499 cases during the year.
Seven countries accounted for about 90 per cent of reported cases and deaths. They include Nigeria, Angola, Bangladesh, the Democratic Republic of Congo, South Sudan, Sudan and Yemen.
Nigeria remains one of the countries affected by the disease. WHO data shows that the country recorded 72,374 cholera and acute watery diarrhoea cases between January 1 and September 27, 2026.
The figures also include 467 deaths. Borno State accounted for 96 per cent of the reported cases. Monguno, Damboa and Konduga were among the affected local government areas.
WHO has warned that the El Niño weather pattern could increase the risk of cholera outbreaks. Flooding can contaminate sources of drinking water. Water shortages can also force people to use unsafe supplies.
Cholera spreads through food and water contaminated by the bacteria that cause the disease. Without quick treatment, patients can suffer severe dehydration. In serious cases, the disease can cause death within hours.
WHO and Gavi are working to reduce cholera cases worldwide by 90 per cent by 2030. Their plan focuses on vaccination, clean drinking water and better sanitation.
The strategy also includes early detection and faster treatment. In 2025, the International Coordinating Group approved 71 million doses of oral cholera vaccines for affected countries.
WHO says stronger disease surveillance and better access to healthcare are also important. Governments must invest in clean water and proper sanitation to prevent further outbreaks and save lives.
