This follows projections by the Nigerian Meteorological Agency and the Federal Ministry of Environment, which indicated that parts of Adamawa, Enugu, Kaduna, Kogi, Niger, Osun, Oyo, Plateau, Taraba, and Kwara states may experience heavy rains between April 13 and April 17.
The NCDC said the rainfall forecast coincides with the period when cholera cases typically begin to rise in Nigeria, warning that flooding could worsen disease transmission.
According to Idris, recent surveillance data already show increasing cholera activity across multiple states, raising concerns about potential outbreaks.
He stated that flooding increases public health risks by contaminating drinking water sources, disrupting sanitation systems, and exposing communities to unsafe environmental conditions.
The agency also warned that beyond cholera, flooding could lead to other health risks, including malaria and other mosquito-borne diseases, infections from contaminated water, injuries such as drowning and snakebites, and disruption to healthcare access.
The NCDC advised residents in affected areas to take preventive measures, including using safe water for drinking and cooking through boiling, chlorination, or bottled sources.
It also urged strict hand hygiene, proper sanitation, and safe food storage practices to prevent contamination.
Residents were advised to avoid contact with floodwaters and to sleep under insecticide-treated nets to reduce the risk of mosquito-borne diseases.
Cholera is an acute diarrhoeal disease caused by consuming water or food contaminated with Vibrio cholerae.
The disease spreads rapidly in areas with poor sanitation and unsafe water, particularly during flooding, and can lead to severe dehydration and death if not treated promptly.
The burden of the disease is driven by factors such as flooding, overcrowding, and weak sanitation infrastructure, making children, rural populations, and displaced persons particularly vulnerable.
Despite being preventable and treatable, cholera continues to strain the country’s health system during peak outbreak periods.
