Florida records first Vibrio vulnificus death in 2026, with additional cases reported statewide

Florida health officials have confirmed the state's first death from Vibrio vulnificus, a bacterium that can cause severe skin and systemic infections. The fatality occurred in Palm Beach County, marking the first reported Vibrio-related death in the United States for 2026. In addition to the fatal case, eleven other Vibrio infections have been identified across Florida.

The Centers for Disease Control and Prevention notes that Vibrio species thrive in warm, coastal waters and can cause symptoms such as nausea, diarrhea, fever, low blood pressure and skin lesions. While roughly 80,000 cases of vibriosis are estimated annually in the United States, infections with Vibrio vulnificus are particularly serious, with about 20% of patients dying.

Transmission typically occurs when the bacteria enter an open wound during exposure to salt or brackish water, or through consumption of raw, contaminated shellfish. The Florida Health Department has not disclosed the exact date of the Palm Beach County death.

Separately, the Mobile County Health Department in Alabama reported its first vibriosis case of the year on April 24.
