Florida is currently leading the United States in cases of Vibrio vulnificus, a rare but deadly flesh-eating bacteria that thrives in warm, brackish coastal waters. In 2025, the Florida Department of Health has reported 11 confirmed cases statewide, including infections in Lee County, Manatee County, and St. Johns County. The bacteria has resulted in four fatalities so far this year, with one death occurring near Jacksonville and another in the Tampa Bay area. Health officials have issued warnings advising the public to avoid exposure to coastal waters if they have open wounds, as the bacteria can enter through skin injuries. Infections with Vibrio vulnificus, although uncommon, can lead to severe medical outcomes such as intensive care treatment or limb amputation. The resurgence of this bacteria coincides with the region's hurricane season, which may contribute to its presence in Florida's waters.
