Waterborne diseases are illnesses caused by tiny living organisms, called pathogens, such as bacteria, viruses, or parasites, that are transmitted through contaminated water. After a flood, regular water sources become easily compromised because floodwaters mix with sewage, overflowing latrines, and other waste, introducing these pathogens into the environment.
