Common pathogens include: Bacteria such as E. coli and Salmonella Viruses including Hepatitis A and Norovirus Parasites like Giardia In addition to biological hazards, floodwaters may hold chemical contaminants from submerged vehicles, industrial sites, and agricultural areas. Pollutants may cause respiratory issues or skin irritations upon contact. Short-Term and Long-Term Health Effects Short-term health effects from floodwater exposure can include: Gastrointestinal illnesses Skin infections Respiratory problems due to mold exposure These conditions may appear within days of exposure. Long-term effects may develop from prolonged exposure or when contaminated materials remain in the home. Chronic health issues can surface, such as persistent respiratory conditions, allergies, and autoimmune responses triggered by mold or bacteria. It is imperative for affected individuals to address these risks promptly.  Vulnerable Populations in the Home Certain groups face higher risks during flood events. Vulnerable populations include: Children : Their immune systems are still developing, making them more susceptible to infections. Elderly individuals : They often have pre-existing health conditions that can be exacerbated by exposure. Pregnant women : They may be at risk of complications from infections or exposures. Homeowners should take extra precautions to protect these individuals, including ensuring that any cleanup following flooding is conducted by professionals equipped to handle contaminated materials safely.
