Floods have a significant negative impact on public health, particularly for vulnerable groups like pregnant women, children, and the elderly. Health services are often poor or non-existent during floods when demand increases. CHARM has responded in past floods by distributing sanitary supplies, providing medical training, and setting up referrals; however, providing medical care during floods remains a challenge. A customized action plan is needed that involves stakeholders, assesses vulnerabilities, estimates health impacts, and prepares mitigation, preparedness, and response strategies.
