Flood-prone areas in Tamil Nadu, including Chennai and coastal districts, face heightened risks of disease outbreaks and disruptions to healthcare services during the monsoon. Vulnerable populations, such as pregnant women and those in low-lying areas, are particularly at risk. Hospitals must ensure uninterrupted oxygen supply, functional life-saving equipment, and adequate medical personnel to address emergencies. Failure to prepare could lead to increased morbidity and mortality during extreme weather events.
