  • Florida has already recorded four deaths this year from Vibrio vulnificus, a flesh-eating bacterium, following a record number of cases in 2023.
  • Last year saw 19 deaths and 82 cases, a significant increase attributed to late-season hurricanes Milton and Helene, which caused saltwater to move inland.
  • Vibrio vulnificus infections, though rare, can be fatal, especially for those with weakened immune systems, and can lead to severe outcomes like amputation.
