As Iowans face continued flooding, questions are being raised about exposure to diseases like tetanus and hepatitis A. Iowa Department of Public Health spokesperson Polly Carver-Kimm says neither of these illnesses has been found to be associated with flooding, and mass vaccinations are not necessary.

(IDPH1) :10 “It’s understandable that folks are anxious – however, it’s important to understand that flooding has not been shown to be a risk factor for either tetanus or hepatitis A.”

Carver-Kimm says vaccinations are only needed under certain conditions.

(IDPH2) :26 “If you or a family member has been cut or scraped or the skin broken while working in flood waters, you should check your immunization records. If you have not received a tetanus booster in the last five years, or if you’re unsure about your vaccinations, you should see your medical provider about a vaccination. Otherwise, if your vaccinations are up to date, you don’t need a vaccination for tetanus or hepatitis A.”

Carver-Kimm says the bigger health threat during flooding is personal injury, especially from carbon monoxide poisoning from the use of gas-powered generators indoors, as well as stress and heat exhaustion. She says as simple as it sounds, the best prevention against any disease from flood waters is regular hand washing with soap and water.
