Surge in Flesh-Eating Bacteria Cases in Florida

WEST PALM BEACH, Fla. — An alarming rise in infections caused by the rare but deadly flesh-eating bacteria, Vibrio vulnificus, has resulted in five fatalities in Florida so far this year. The number of cases has jumped to 20 in just weeks, with a new case confirmed in Martin County by the Florida Department of Health (FDOH).

As of now, FDOH has reported a total of 20 infections linked to this bacterium in 2025 alone.

Just over a month ago, it was noted that there were 11 confirmed instances—with four deaths—demonstrating a significant increase within a short timeframe.

The Centers for Disease Control and Prevention (CDC) highlights that most infections stem from consuming raw or undercooked shellfish, particularly oysters. Additionally, open wounds can get infected if they come into contact with contaminated salt or brackish water.

The CDC has also raised concerns about extreme weather events such as coastal flooding, hurricanes, and storm surges. These conditions can push bacteria-laden coastal waters further inland, posing a heightened risk for those—especially older individuals or those with health issues—who might encounter contaminated water.

Vibrio vulnificus is usually found in warm, saline waters, like those in the Gulf of Mexico and nearby bays, according to health officials. The FDOH indicates that the risk increases with elevated water temperatures.

While infections from Vibrio vulnificus are rare, they can lead to serious health issues. Symptoms often include diarrhea, stomach cramps, nausea, vomiting, fever, and chills. Though antibiotics can treat infections, severe cases might require surgery to remove damaged tissues.

Fast diagnosis is key to effective treatment and recovery. Generally, those with strong immune systems face a lower risk of severe complications, officials say.

The confirmed fatalities in Florida were reported in various counties:

• Bay County – two deaths.
• Broward County
• Hillsborough County
• St. Johns County

Additionally, infection cases have emerged in the following counties:

• Collier County
• Dade County
• Duval County
• Escambia County
• Flagler County
• Lee County
• Manatee County
• Martin County
• Okaloosa County
• St. Johns County
• Santa Rosa County
• Walton County

In 2024, Florida recorded a total of 82 confirmed infections and 19 deaths related to this bacterium.

Each year, Vibrio bacteria are responsible for approximately 80,000 illnesses across the United States. The CDC states that there are around 150 to 200 infections annually, with a mortality rate of about 20%, often leading to death within one to two days after the onset of symptoms.
