Unhealthy Floodwater
Floodwater is more than simple rain. It’s often contaminated with sewage and chemicals and can hide sharp objects made of metal or glass. Sewage can cause boils or rashes on parts of the body that are submerged for extended periods of time, such as legs. Chemicals can cause rashes and burning of the skin and eyes after exposure.
What may be more common will be bouts of diarrhea or other stomach problems if people come into contact with contaminated water or consume food or drink that has. Using items that have been submerged can also cause stomach problems. To cut down on infection, do not let children play with toys that have been in the water unless then have since been thoroughly washed.
Exposure to water damage from floodwater can increase risk for skin rashes, ear, nose and throat problems and conjunctivitis, but the World Health Organization says that none of these is epidemic-prone.
Of 14 major floods between 1970 and 1994, the WHO said, the only major epidemic of diarrheal disease was in Sudan in 1980. American disease control is much more advanced than Sudan’s.
The other major risk is drinking contaminated water — but again, US disease surveillance is likely to minimize that risk.
The occasional personal trainer may be more likely, people having to stay in close quarters with large groups. With a flood, it is hard for people to keep up healthy hygiene standards. When people stay together in shelters with large groups, it’s easy to spread germs.
The CDC highly recommends that people who are staying at shelters be extra careful to wash their hands or to use an alcohol hand gel to prevent the spread of disease. People with open wounds also need to take extra care to keep them covered. Floodwater can easily cause a wound to become infected.
