Florida state health officials reported a record number of Vibrio vulnificus cases and deaths in 2024, triggered by 2 week, back to back hurricanes on the west coast of the state in late September and early October.
According to official state data, Florida reported 83 V. vibrio cases and 18 deaths last year, topping the previous record in the year of Hurricane Ian, 2022, when 74 cases and 17 deaths were recorded.
Last year on September 26, 2024, Hurricane Helene made landfall as a powerful Category 4 storm and two weeks later, on October 9, 2024, Hurricane Milton made landfall in Florida as a dangerous Category 3 storm, wrecking coastal communities that were already struggling to recover from previous storms.
In 2024 Citrus, Hernando, Hillsborough, Lee, Pasco, Pinellas, and Sarasota Counties experienced unusual increase due to the impacts of Hurricane Helene.
Vibrio bacteria, commonly found in warm coastal waters, can cause illness when ingested or when open wounds are exposed to contaminated water. After heavy rainfall and flooding, the concentration of these bacteria may rise, particularly in brackish and saltwater environments.
