Louisiana health officials are warning swimmers about a rise in cases of *Vibrio vulnificus*, a potentially fatal bacterium. The bacteria, often found in warm coastal waters, can cause severe illness and even death through open wounds exposed to seawater. Authorities have reported an increase in infections this year, prompting concern for public health. Symptoms include fever, chills, skin lesions, and vomiting. Individuals with compromised immune systems, liver disease, or open wounds are particularly vulnerable. Officials advise avoiding swimming in saltwater with open wounds and seeking immediate medical attention if infection is suspected. The state is actively monitoring water conditions and providing guidance to the public.
