Health officials in Louisiana are advising beachgoers to take precautions due to an increase in infections from Vibrio vulnificus, a flesh-eating bacteria found in coastal waters. The Louisiana health department reported nine confirmed cases this year, resulting in five deaths. Over the past decade, the average number of cases during the same period was seven, with one death.
Officials recommend seeking immediate medical attention if wounds exposed to brackish or salt water show signs of infection, such as redness, swelling, or discoloration. Vibrio bacteria thrive in seawater and brackish environments, particularly from May to October, with most infections occurring in Gulf Coast states. The Centers for Disease Control and Prevention (CDC) indicates that Vibrio vulnificus has a fatality rate of approximately 20% for those infected.
Florida has reported 14 cases and two deaths from Vibrio vulnificus this year, compared to 33 cases and five deaths last year. Infections are more common among individuals with weakened immune systems, liver disease, diabetes, and other chronic conditions. Health officials note that climate change may be contributing to the bacteria's spread northward.
To protect themselves, beachgoers are advised to wash any cuts or scrapes thoroughly after exposure to coastal waters or raw seafood. Symptoms of infection include fever, chills, and dark blistering skin. The CDC also emphasizes the importance of proper handling and cooking of shellfish, particularly oysters, which can carry the bacteria.
