Cholera Alert: NCDC Flags 10 States Amid Rainfall

The Nigeria Centre for Disease Control and Prevention (NCDC) has placed 10 states on high alert following forecasts of heavy rainfall and potential flooding, warning of an increased risk of disease outbreaks, particularly cholera.

According to the agency’s Director-General, Jide Idris, projections from the Federal Ministry of Environment and the Nigerian Meteorological Agency indicate that states including Adamawa State, Enugu State, Kaduna State, Kogi State, Niger State, Osun State, Oyo State, Plateau State, Taraba State, and Kwara State will experience intense rainfall between April 13 and 17, 2026.

Idris explained that the warning comes during a critical period when cholera cases typically rise, with early surveillance already showing an uptick in infections. “These forecasts are particularly concerning because they coincide with the period when cholera transmission typically accelerates. Flooding can contaminate water sources and disrupt sanitation systems, creating conditions for rapid spread,” he said. He also noted that beyond cholera, there is an increased risk of other diarrhoeal diseases and malaria due to stagnant water creating breeding grounds for mosquitoes.

While highlighting the risks, the NCDC stressed that preventive measures can significantly reduce the impact. “These risks are largely preventable. We urge residents in the affected states to ensure they use safe water, maintain hygiene, avoid contact with floodwaters, and seek prompt medical care if symptoms develop,” Idris said. He further called for stronger community action, adding, “Community-level action is critical. Early reporting of suspected cases and dissemination of accurate health information will go a long way in preventing outbreaks.”

The agency added that it is working with state health authorities to strengthen surveillance and emergency response systems. With seasonal flooding continuing to pose serious public health challenges across Nigeria, officials emphasise that early intervention, improved sanitation, and community awareness will be key to preventing avoidable illnesses and deaths in the coming weeks.
