Florida health officials announced on Sept. 17 that the state has confirmed 22 cases of Vibrio vulnificus infection in 2026, a rare but potentially fatal bacterium found in brackish water and raw seafood. Four of those cases have resulted in death, occurring in Bay, Broward, Marion and Palm Beach counties. The latest update added a new confirmed case in Santa Rosa County, involving a patient aged between 25 and 29, for the reporting period that ended Sept. 12.
Statewide case count and recent update
The Florida Department of Health does not release identifying details beyond age range for the most recent patient. The cumulative toll for 2026 now stands at 22 confirmed infections and four deaths, compared with 33 cases and five deaths recorded in 2025. County‑by‑county data through Aug. 15 show the distribution of cases: Bay (2), Brevard (1), Broward (2), Duval (1), Hillsborough (1), Lee (2), Marion (2), Miami‑Dade (2), Okaloosa (1), Palm Beach (2), Polk (2), Santa Rosa (now 3), and St. Johns (1). The four fatalities are each linked to Bay, Broward, Marion and Palm Beach counties.
Regional context along the Gulf Coast
The rise in Florida mirrors activity elsewhere along the Gulf. Louisiana health officials reported 17 cases and six deaths as of Sept. 16, with the majority (16) linked to wound or seawater exposure. In Alabama, the Mobile County Health Department documented 11 cases of vibriosis through Sept. 12, while the Mississippi Department of Health recorded three cases as of August. Texas health authorities have noted four cases, and South Carolina, which does not require mandatory reporting, indicated awareness of three cases and one related death this year.
According to the Centers for Disease Control and Prevention, about one in five people who develop a Vibrio vulnificus infection die, underscoring the bacterium’s rapid progression. Symptoms can appear within 24 hours of exposure and may include watery diarrhea, stomach cramps, fever, blistering skin lesions, low blood pressure, and sepsis. The infection can spread to the bloodstream and internal organs within hours, often necessitating emergency surgery or even amputation to halt tissue damage.
Prevention and public health guidance
Health officials emphasize that anyone can contract the infection, but individuals with compromised immune systems—such as those with liver disease, cancer, diabetes, HIV, thalassemia, or those taking immunosuppressive or acid‑reducing medications—face the greatest risk of severe illness. The CDC describes Vibrio vulnificus as “flesh‑eating bacteria” because it can cause necrotizing fasciitis, rapidly destroying muscle and skin tissue.
Public health recommendations include avoiding exposure of open wounds to brackish water, which is found in bays, estuaries, river mouths and flood zones. This guidance extends to recent surgical sites, fresh tattoos, piercings and even minor cuts or scrapes. After water exposure, individuals should wash any exposed skin with soap and running water. Cooking seafood—particularly oysters—thoroughly and washing hands and surfaces after handling raw seafood are also advised. High‑risk individuals are encouraged to wear gloves when handling raw shellfish.
Genevieve Gallagher of Pensacola, who lost her left leg below the knee after a Vibrio infection last year, warned that even small cuts can provide an entry point for the bacteria. “Going to the beach for a day of fun is not worth it,” she told local TV, adding that shaved skin or mosquito bites can create microscopic openings for infection.
Medical professionals urge anyone who develops symptoms after consuming raw seafood or after contact with brackish water to seek immediate care, as early treatment improves outcomes.
