Five Vibrio vulnificus infections have been confirmed across five Florida counties since the start of 2026, and state health officials expect more cases as coastal waters warm.
One 74-year-old patient highlighted in a New England Journal of Medicine study developed a severe wound infection after swimming in the Gulf Coast with a cut on his leg and ultimately needed an above-the-knee amputation.
The CDC says the bacteria lives in coastal waters and can infect people through open wounds or by consuming raw or undercooked shellfish.
About 1 in 5 infections is fatal, with wound cases causing fever, low blood pressure, blistering skin lesions, swelling and discharge, while foodborne cases more often bring diarrhea, cramping, nausea, vomiting and fever.
