More than 150 deaths across the Southeast had been attributed to Hurricane Helene within days of the late September 2024 storm, according to The Associated Press, and hundreds of people remained unaccounted for. In many areas hit by flooding, homes were left isolated by damaged roads and bridges. Phone service was down. And electricity was likely to be out for weeks. WATCH: Asheville mayor on what North Carolina needs as flooding recovery process begins As a disaster epidemiologist and a native North Carolinian, I have been hearing stories from the region that are devastating. Contaminated water is one of the leading health risks, but residents also face harm to mental health, stress that exacerbates chronic diseases and several other threats. Water risks: What you can’t see can hurt you Access to clean water is one of the most urgent health concerns after a flood. People need water for drinking, preparing food, cleaning, bathing, even flushing toilets. Contact with contaminated water can cause serious illnesses. Floodwater with sewage or other harmful contaminants in it can lead to infectious diseases, particularly among people who are already ill, immunocompromised or have open wounds. Even after the water recedes, residents may underestimate the potential for contamination by unseen bacteria such as fecal coliform, heavy metals such as lead, and organic and inorganic contaminants such as pesticides. In Asheville, the flooding caused so much damage to water treatment facilities and pipes that officials warned the city could be without running water for potentially weeks. Most private wells also require electricity to pump and filter the water, and many people in surrounding areas could be without power for weeks. READ MORE: Helene and other storms dumped 40 trillion gallons of rain on the South State and federal agencies began delivering extra bottled water to the region shortly after the storm, but supplies were limited, and it’s likely that a number of people won’t be able to reach the distribution sites soon. Access to fresh food is another concern for many areas with roads and bridges washed out. Inside homes, floodwater can create more health risks, particularly if mold grows on wet fabrics and wallboard. Standing water outside also increases the risk of exposure to mosquitoes carrying diseases such as West Nile virus. Mosquitoes are still active in much of the region in the fall. Inundation, isolation and access to health care Many of the images in the news after the hurricane hit showed roads, hospitals and entire towns inundated by floodwaters. In North Carolina, more than 400 roads were closed, blocking access to the major regional health care hub of Asheville, as well as many smaller communities. While supplies can be airlifted to clinics, residents needing urgent access to treatments such as dialysis or daily medications for substance use disorders may have been cut off. Health care workers may be unable to access their clinics as well. Cuts and other injuries are common in the aftermath of storms, as people clean up debris, and even small wounds can become infected. The stress, exertion and exposure to heat can also exacerbate chronic conditions such as cardiovascular and respiratory diseases.

All of those conditions were present as Hurricane Helene’s floodwaters swept away dozens of people, with many more still listed as missing.
