Bold warning: flesh-eating bacteria cases near popular beaches are on the rise, and travelers should be extra vigilant.
Florida’s health officials have reported two new infections of Vibrio vulnificus, a bacteria that thrives in warm coastal waters and can invade open wounds. The latest cases occurred in Lee County (home to Fort Myers) and Nassau County, both within the past week. Details about hospitalization, amputations, or treatment have not been disclosed.
These two cases bring Florida’s total for the year to 33 infections, with five deaths nationwide so far. Notably, Nassau and Lee Counties have not recorded any deaths this year, though Lee County has documented four cases and Nassau one.
Across the United States in 2025, at least 72 cases have been reported across 12 states, predominantly in the southern region, with a single case reaching as far north as Massachusetts.
Louisiana, in particular, is experiencing a sharp rise, reporting 26 infections and five deaths so far this year—well above the typical annual range of seven to ten infections.
Vibrio bacteria naturally dwell in coastal waters and tend to be more abundant from May through October when water temperatures rise. Warning signs of infection include a rapidly reddening or swollen skin, a painful rash, fluid-filled blisters, fever, and, in some cases, altered mental state. In severe scenarios, infections can spread to the bloodstream, leading to sepsis, and may necessitate limb amputation.
According to the CDC, about 20% of those infected with Vibrio die, and roughly 80% require hospitalization. Individuals at higher risk include those with weakened immune systems, older adults, and people who eat raw or undercooked seafood.
Florida’s December 5 update confirmed the two new cases but provided limited further information. The state health department emphasizes that Vibrio vulnificus is a naturally occurring bacterium in warm, brackish water and cautions that water and open wounds should not mix. The guidance is clear: avoid entering the water with fresh cuts or scrapes.
Comparatively, Florida’s Vibrio totals for 2024 and 2023 show fluctuations: 2024 saw at least 82 cases and 19 deaths, while 2023 recorded 46 infections and 11 deaths. Nationally, the United States reported 82 cases and 19 deaths in 2024, also higher than the current year’s figures.
A prior Florida case involved a 49-year-old woman who contracted Vibrio while swimming off Pensacola Beach in July. She faced septic shock and near organ failure, with doctors describing extreme pain and rapid swelling of her leg. Treatment included aggressive medical intervention and surgery.
Another earlier case involved an 88-year-old man who developed Vibrio after handling fish from a dock. He noticed a leg bruise that worsened over time and required hospitalization and antibiotics.
Treatment options for Vibrio infections generally include antibiotics, drainage of blisters, and intravenous fluids. In severe situations, limb amputation may be necessary to control the infection and prevent further complications.
