Nigeria is facing an increased risk of disease outbreaks, particularly cholera, due to anticipated heavy rainfall and flooding in several states. The Nigeria Centre for Disease Control and Prevention (NCDC) has issued a public health advisory in response to forecasts from the Federal Ministry of Environment and the Nigerian Meteorological Agency (NiMet), which predict significant rainfall and potential flooding between April 13 and 17, 2026. High-risk areas identified include Adamawa, Enugu, Kaduna, Kogi, Niger, Osun, Oyo, Plateau, Taraba, and Kwara.
The NCDC warns that flooding can lead to outbreaks of cholera and other diarrheal diseases, as well as an increase in malaria cases, infections from contaminated water, injuries, and disruptions to healthcare services. To mitigate these risks, the agency urges residents in affected areas to take preventive measures. These include drinking only safe water—either boiled or chlorinated—practicing proper hand hygiene, and avoiding contact with floodwaters. Additional recommendations involve proper food storage, improved sanitation practices, and the use of insecticide-treated mosquito nets to reduce the risk of malaria.
Individuals experiencing symptoms such as diarrhea, vomiting, or fever are advised to seek immediate medical attention. The NCDC is also calling on community leaders to enhance public awareness campaigns, promote sanitation, ensure access to clean water, and encourage early reporting of suspected illnesses. Furthermore, the NCDC is working with state governments to strengthen disease surveillance, preparedness, and emergency response efforts to address the potential health impacts of the predicted floods.
This advisory comes amid growing concerns regarding the public health implications of seasonal flooding, which has historically resulted in 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.
