Cholera Outbreak in Africa: What You Must Know & How to Prevent It

In 2025, many African countries are battling what experts call the worst cholera outbreak in 25 years — with over 300,000 suspected or confirmed cases and thousands of deaths reported so far across the continent.

What is cholera?

Cholera is an acute bacterial infection (caused by Vibrio cholerae) that spreads through contaminated water or food. It causes severe vomiting and diarrhea — which can lead to deadly dehydration within hours if untreated.

How to prevent cholera

Ensure access to safe drinking water: treat or boil water before drinking.

Practice good hygiene — wash hands regularly with soap, especially before eating or preparing food, and after using the toilet.

Maintain proper sanitation — safe disposal of sewage and waste, avoid open defecation, keep food clean.

During outbreaks, organize and support oral-cholera-vaccine (OCV) campaigns in high-risk areas — vaccines, along with WASH (water/sanitation/hygiene) interventions, dramatically reduce spread and fatalities.

Why this matters now

With rapidly rising cases in 2025, cholera has become a public-health emergency across several African nations.

It’s a stark reminder: access to clean water, proper sanitation and hygiene — basic necessities — remains critical in the fight against cholera. Communities, governments and international agencies must work together to expand WASH infrastructure, deliver vaccines, educate people — and prevent future outbreaks.
