Orlando, Fla. – The Florida Department of Health (FDOH) has confirmed three new cases of Vibrio vulnificus—a dangerous bacteria often referred to as a “flesh-eating” infection—bringing the total to 28 reported cases in 2025. The latest cases were identified in Citrus, Collier, and Lee counties.

Health officials say the bacteria, which thrives in warm, brackish water, has already been linked to five deaths across Florida this year. The fatalities occurred in Bay, Broward, Hillsborough, and St. Johns counties.

What is Vibrio vulnificus?

Vibrio vulnificus is a salt-loving bacteria that can cause severe and sometimes fatal infections, particularly in individuals with weakened immune systems. Those with chronic liver or kidney disease are considered at higher risk of serious illness.

The bacterium is found naturally in coastal waters and poses a greater threat during the warmer months, when water temperatures rise. It can infect open wounds exposed to seawater or brackish water and, in severe cases, lead to bloodstream infections and sepsis.

Safety Precautions

The FDOH is urging Floridians and visitors to take extra precautions:

Avoid swimming in warm seawater with open wounds, cuts, or scrapes. Wear protective footwear to prevent injuries from rocks and shells while walking along beaches. Immunocompromised individuals should be especially cautious, as they are more vulnerable to infection.

“Taking simple steps can dramatically reduce the risk of infection,” health officials emphasized, reminding the public that even minor cuts or scrapes can serve as an entry point for the bacteria.

Monitoring the Situation

As the number of cases climbs, state health officials are closely monitoring coastal waters and continuing to raise awareness. They encourage residents and tourists alike to remain vigilant, particularly during Florida’s hot and humid months when conditions are ideal for the bacteria to spread.
