Cholera, Zika, and West Nile: The Deadly Diseases That Sweep in After Hurricanes

Summary

Hurricanes not only cause physical destruction but also fuel disease outbreaks, as shown in recent studies on post-storm health impacts in the U.S. and Caribbean. Floodwaters from storms like Hurricanes Helene and Milton spread pathogens like Vibrio vulnificus, which has already caused numerous infections and fatalities in Florida. Besides waterborne bacteria, stagnant floodwaters create breeding grounds for mosquito-borne illnesses such as West Nile, Zika, and dengue. Mould growth in flooded homes also leads to respiratory issues. Experts warn that extreme weather increases disease risks, disproportionately affecting vulnerable populations, and advocate for better mobile healthcare and emergency responses in disaster-prone areas.
