Florida records first Vibrio vulnificus death of 2026, with additional cases reported in Alabama and Connecticut

Florida health officials have confirmed the state's first death from Vibrio vulnificus, a flesh-eating bacterium, marking the first such fatality in the United States in 2026. The death occurred in Palm Beach County, though the exact date has not been disclosed. Eleven additional Vibrio cases have been identified in Florida.

The Centers for Disease Control and Prevention notes that Vibrio bacteria thrive in warm, coastal waters and can cause symptoms such as nausea, diarrhea, fever, low blood pressure and skin lesions. While roughly 80,000 vibriosis cases are estimated annually in the United States, the CDC says about one in five infections with Vibrio vulnificus are fatal.

Infection can result from exposure of an open wound to salt or brackish water, or from consuming raw, contaminated shellfish. The Mobile County Health Department in Alabama reported its first vibriosis case of the year on April 24, and Connecticut health officials have also documented infections.

"Vibrio bacteria live in warm, coastal waters and infections can cause a number of symptoms including nausea, diarrhea, fever, low blood pressure and blistering skin lesions," the CDC stated.

Public health agencies continue to monitor the situation and advise caution when swimming in affected waters or eating raw shellfish.
