Florida reports 14 cases of Vibrio vulnificus infections as survivors warn of risks

The Florida Department of Health has confirmed 14 cases of Vibrio vulnificus infections, sometimes referred to as "flesh-eating bacteria," across the state in 2024. One recent case involved a child in Brevard County, and other cases have been reported in Marion and Polk counties, including a fatality in Marion.

Genevieve Gallagher, who survived a severe infection after a boating trip with her family in 2025, said a cut on her leg became infected and led to extensive tissue loss below her kneecap. She described the illness as rapidly worsening after a few days, noting that she experienced fever, sweating, and loss of consciousness before being hospitalized.

"This will turn your life upside down," Gallagher said.

Family medicine physician Dr. Autumn Barnes of Health First explained that the term "flesh-eating bacteria" is a misnomer and that the condition, necrotizing fasciitis, is caused by specific bacteria such as Vibrio vulnificus. She said infection can occur through consumption of raw or undercooked shellfish, particularly oysters, or through open wounds exposed to warm salt or brackish water. While the infection is rare, Dr. Barnes noted that individuals with compromised immune systems are at higher risk and that prompt medical attention is essential.

"Not everyone who is exposed to it is going to get this infection. It is fairly rare," she said.

Gallagher, who has no known immune deficiencies, urged beachgoers to keep cuts and minor skin injuries clean and covered, warning that even small abrasions can provide an entry point for the bacteria.

"Going to the beach for a day of fun is not worth it if you have a cut on your leg or a mosquito bite that you scratched and it’s open," she said.

Health officials continue to monitor cases and advise the public to seek immediate care for any rapidly spreading wound infections, especially after exposure to warm coastal waters.
