Louisiana Reports 17 Vibrio Cases, 4 Deaths From Flesh-Eating Bacteria

Louisiana health officials report a significant increase in infections caused by Vibrio vulnificus, a dangerous flesh-eating bacteria found in warm coastal waters, with 17 cases and four deaths so far in 2025, surpassing the usual annual averages. The majority of infections involved individuals with open wounds exposed to salt or brackish water, and the bacteria thrive in water temperatures between May and October, increasing risk during warmer months. Symptoms can include fever, chills, vomiting, wound infections, and blistering skin lesions, with severe cases requiring hospitalization and sometimes limb amputation. People with weakened immune systems or preexisting conditions such as liver disease are at heightened risk and should take precautions like avoiding swimming with open wounds, wearing protective clothing, and exercising caution when handling or consuming raw or undercooked seafood. Health officials urge those who develop skin infections after exposure to seek immediate medical attention. The Louisiana Department of Health emphasizes washing wounds and hands thoroughly and covering any cuts when near coastal waters to reduce the risk of infection.
