In the aftermath of recent heavy flooding across Lagos and various regions in Nigeria, public health experts are raising alarms about a secondary disaster. While media coverage has focused on submerged structures and transportation disruptions, specialists emphasize that the risk to human health actually intensifies once the waters begin to withdraw.
Dr. Adedayo Aderibigbe from the Lagos State University Teaching Hospital notes that the core issue is the contamination left behind. Floodwaters are often laden with sewage, refuse, and fecal matter, creating a perfect environment for the transmission of cholera, typhoid, and various diarrheal illnesses. Furthermore, stagnant pools serve as prime breeding zones for mosquitoes, leading to anticipated spikes in malaria cases.
The experts point to human behavior as a significant contributor to the severity of these events. Indiscriminate waste disposal, the obstruction of drainage networks, and unauthorized construction on natural waterways prevent floodwaters from draining effectively. This failure of urban infrastructure forces contaminated water into homes and food supplies.
Dr. Doyin Odubanjo of the Nigerian Academy of Science highlights that the psychological toll and food insecurity are often ignored. The uncertainty surrounding daily survival and the destruction of crops contribute to a broader socioeconomic crisis. Both physicians urge the government to move beyond reactive measures. They advocate for consistent disease surveillance, the pre-positioning of medical supplies in hospitals, and the strict enforcement of environmental building codes.
For the public, the experts recommend boiling drinking water, practicing rigorous hand hygiene, and maintaining clean food preparation areas. They stress that waiting for outbreaks to manifest before taking action is a dangerous strategy. Proactive sanitation and community education remain the most effective methods to prevent avoidable loss of life in the post-flood period.
