Nigeria Faces Heightened Disease Outbreak Risk Amid Expected Flooding
The Nigeria Centre for Disease Control and Prevention (NCDC) has issued a public health advisory warning of increased risks of cholera and other disease outbreaks following anticipated heavy rainfall and flooding across several states.
The Federal Ministry of Environment and the Nigerian Meteorological Agency (NiMet) have forecast heavy rainfall and potential flooding between April 13 and 17, 2026. States identified as high-risk areas include Adamawa, Enugu, Kaduna, Kogi, Niger, Osun, Oyo, Plateau, Taraba, and Kwara.
The NCDC has highlighted that flooding could trigger outbreaks of cholera and other diarrhoeal diseases, while also increasing malaria cases, infections from contaminated water, injuries, and disruptions to healthcare services. The agency is urging residents in affected areas to take preventive measures, including drinking only safe water—either boiled or chlorinated—maintaining proper hand hygiene, and avoiding contact with floodwaters.
Additional recommendations include proper food storage, improved sanitation practices, and the use of insecticide-treated mosquito nets to reduce malaria risk. The NCDC advises that anyone experiencing symptoms such as diarrhoea, vomiting, or fever should seek immediate medical attention.
Community leaders are being called upon to intensify public awareness campaigns, promote sanitation, ensure access to clean water, and encourage early reporting of suspected illness. The NCDC is collaborating with state governments to strengthen disease surveillance, preparedness, and emergency response efforts to mitigate the potential health impact of the predicted floods.
The advisory comes amid growing concerns over the public health implications of seasonal flooding, which has historically led to disease outbreaks in vulnerable communities across Nigeria. The NCDC’s proactive measures aim to protect public health and minimize the impact of flooding-related diseases during this critical period.
