Watan-At least four people have died in the U.S. state of Florida this year after being infected with a flesh-eating bacteria commonly found in warm or brackish saltwater, according to the Florida Department of Health. A total of 11 cases have been reported so far in 2025.
The infection is caused by the Vibrio vulnificus bacterium — a rare but dangerous pathogen that can lead to necrotizing fasciitis, a severe condition in which tissue surrounding an open wound dies. According to the Centers for Disease Control and Prevention (CDC), many patients require intensive care or limb amputation, and approximately 1 in 5 infected individuals dies, sometimes within just 48 hours of symptom onset.
What Is Vibrio vulnificus?
Vibrio vulnificus thrives in warm, coastal, saltwater or brackish environments, especially where rivers meet the sea. It is labeled “flesh-eating” because certain infections can result in necrotizing fasciitis.
The bacteria are most active between May and October, particularly in warm, low-salinity marine environments such as estuaries and river deltas.
How Does the Infection Spread?
People can become infected through:
-
Open wounds exposed to warm or brackish water containing the bacteria.
-
Consuming raw or undercooked seafood, particularly raw oysters.
Storm surges, coastal flooding, and hurricanes can push contaminated water inland, increasing the risk of exposure. As ocean temperatures rise, experts warn such infections may become more frequent.
Those at higher risk include:
-
People with liver disease, cancer, or weakened immune systems.
-
Individuals on medications that reduce stomach acid.
There is no evidence that Vibrio vulnificus spreads from person to person, according to Florida health officials.
What Are the Symptoms?
-
Vomiting, diarrhea, abdominal pain
-
Skin ulcerations, fever, chills, low blood pressure
-
Invasive infections can cause blistering and rapid tissue decay
Although healthy individuals may experience mild symptoms, immunocompromised people face a significantly higher risk of serious complications or death
