Louisiana health officials warn of Vibrio vulnificus surge after five deaths
Health officials in Louisiana have issued a warning following a surge in severe infections from Vibrio vulnificus, a bacterium often referred to as "flesh-eating bacteria." So far in 2026, the state has recorded nine confirmed cases, five of which resulted in death. All nine patients were hospitalized, and significantly, all cases were linked to open wounds being exposed to seawater rather than the consumption of contaminated seafood.
The current mortality rate and case count in Louisiana are notable when compared to historical data. Over the previous decade, the state averaged seven cases and one death annually during this period. All patients involved in this year's cases had underlying health conditions.
Vibrio vulnificus occurs naturally in warm coastal and brackish waters, with concentrations typically increasing between May and October. While infection can occur through eating raw or undercooked shellfish, particularly oysters, a high percentage of recent cases resulted from seawater contact with skin breaks, such as cuts, scrapes, or recent tattoos.
Health authorities warn that approximately one in five people with this infection die. High-risk groups include individuals with liver disease, cancer, diabetes, HIV, or thalassemia, as well as those undergoing immunosuppressive treatment. Officials advise beachgoers to cover wounds with waterproof bandages and to seek immediate medical attention if a wound becomes red, swollen, painful, or discolored after water exposure.
