Fifth Florida Resident Dies From Flesh-Eating Bacteria This Year

A fifth person in Florida has died this year from an infection with Vibrio vulnificus, a dangerous bacteria found in warm coastal waters, state health officials announced. The individual, who lived in Pinellas County and was between 50 and 54 years old, was diagnosed with the pathogen, which can enter the body through open wounds.

Nationwide, at least 15 deaths have been attributed to Vibrio vulnificus so far this year. Louisiana has reported seven deaths, North Carolina two, and South Carolina one. The total number of cases across the U.S. has reached at least 55, with infections reported in at least seven states, including those in the South and Northeast.

Florida has recorded 23 cases and five deaths from Vibrio vulnificus in 2024, among the highest totals in the country. The state has experienced unusually warm conditions this year, contributing to the rise in infections. Warmer ocean temperatures are also suspected to extend the period during which the bacteria can thrive.

Understanding Vibrio Vulnificus

Vibrio vulnificus is a bacterium that commonly inhabits warm, brackish coastal waters, such as those found along Florida's Gulf Coast. It can thrive in seawater temperatures above 68°F (20°C). Infections typically occur when open wounds are exposed to contaminated water, or when individuals consume raw or undercooked seafood, particularly oysters.

While the disease remains rare, it can be deadly. The Centers for Disease Control and Prevention estimates that 150 to 200 infections occur annually in the U.S., with approximately one in five cases resulting in death. Symptoms of a Vibrio vulnificus infection can include fever, pain, skin redness or swelling, and fluid-filled blisters. In severe cases, the bacteria can cause flesh to turn black, potentially necessitating amputation, or spread into the bloodstream, leading to sepsis.

Risk Factors and Prevention

Certain populations are at higher risk for severe illness, including older adults, individuals with compromised immune systems, and those who consume raw or undercooked seafood. Vibrio vulnificus infections can be treated with surgery to remove infected tissue, medications to manage blood pressure and sepsis, IV fluids, oxygen therapy, and antibiotics.

To reduce the risk of infection, health officials advise:

• Avoiding swimming in warm ocean water if you have open wounds, cuts, or scrapes.
• Covering any wounds with waterproof bandages before entering the water.
• Washing cuts with soap and water immediately after swimming.
• Avoiding raw or undercooked oysters and shellfish.
• Wearing gloves when handling raw seafood.

Florida has seen Vibrio vulnificus cases and deaths across multiple counties this year. Pinellas County, where the most recent fatality occurred, had recorded 15 infections and three deaths in 2023. Health officials continue to monitor the situation and urge the public to take precautions, especially during warmer months when the bacteria is more prevalent.
