A rare but deadly flesh-eating bacterial infection known as Vibrio vulnificus has claimed the life of a St. Johns County resident, bringing the total number of deaths statewide to 11 this year.
Florida’s health department reports three additional fatalities from the bacteria, with about 80,000 cases of vibriosis occurring annually in the US. Dr. Shalika Katugaha, medical director of infectious disease at Baptist Health, notes that despite its rarity, warmer temperatures and coastal waters increase the risk of infection.
The Centers for Disease Control estimate Vibrio vulnificus thrives in certain coastal waters from May to October when water temperatures rise. The bacteria can be contracted by eating undercooked or raw shellfish, such as oysters or mussels, which filter contaminated water into their shells.
People with weakened immune systems, including those with liver disease, diabetes, or taking medications that suppress the immune system, are at a higher risk of contracting Vibrio vulnificus. Early symptoms include nausea, vomiting, diarrhea, fever, and chills after eating contaminated seafood. If infected through a wound, signs may include redness, swelling, and pain.
Dr. Katugaha urges anyone experiencing these symptoms to seek medical attention promptly, as the infection can be managed with antibiotics but requires early detection and aggressive treatment.
