Florida records first 2026 death from Vibrio vulnificus infection

Florida health officials reported the state's first death in 2026 from the bacterium Vibrio vulnificus, a flesh-eating pathogen that thrives in warm coastal waters. The fatality occurred in Palm Beach County and marks the first U.S. death from the bacterium this year. The Florida Department of Health has confirmed 12 cases statewide, while neighboring Alabama reported six cases and Connecticut identified one case earlier in February.

Vibrio vulnificus infections are rare, with the CDC estimating 100 to 200 cases annually in the United States, but they can be severe. > "About 1 in 5 people with this infection die, sometimes within a day or two of becoming ill," the CDC said. > "Many people with [Vibrio] vulnificus wound infection require intensive care or surgical tissue removal," the agency added.

The bacteria proliferate in warm salt and brackish waters from May through October, especially along the Gulf Coast. Infection can occur through open wounds exposed to contaminated water or seafood, or by consuming raw or undercooked shellfish such as oysters. Symptoms range from gastrointestinal upset to severe bloodstream or wound infections, which may present with fever, chills, low blood pressure, skin lesions, and tissue damage.

Health authorities advise anyone with suspected infection to seek emergency care immediately. People with liver disease, diabetes, or weakened immune systems are at higher risk. The Florida health department and the CDC recommend avoiding exposure of open wounds to seawater, cooking shellfish thoroughly, and promptly cleaning any injuries that occur while swimming or handling seafood.
