Louisiana health officials reported nine Vibrio vulnificus cases and five deaths so far this year. All nine infections were linked to people entering seawater with open wounds, and every infected patient had existing medical conditions.
The state said it has averaged seven cases and one death in previous years. That gap is why the current toll stands out: five deaths is a much higher share of the nine reported cases than Louisiana has typically seen.

Dr. Marc Siegel shared how to stay protected from Vibrio vulnificus on Live. He pointed to the period from May to October, when Vibrio bacteria are found in higher numbers because water temperatures are warmer.
Louisiana health officials warned that Vibrio vulnificus can cause vibriosis with vomiting, diarrhea and abdominal pain. They also said it can cause severe skin infections, and that people with severe infections may require intensive care or limb amputation.
Louisiana Department of Health
The Louisiana Department of Health said about one in five people with Vibrio vulnificus infection dies, sometimes within a day or two of becoming ill. It also listed the first signs of a skin infection as fever, redness, pain, swelling, warmth, discoloration and discharge.
If the bacteria enter the bloodstream, the department said, it can lead to fever, chills, septic shock and blistering skin lesions. For beachgoers, the practical step is to avoid seawater with open wounds and take extra precautions before entering the water, especially during the warmer months when Vibrio bacteria are more common.
Vibrio vulnificus cases
The current Louisiana pattern is narrower than the broader warning around seafood and coastal water exposure, but it is more serious than the state’s usual year. Louisiana has not just seen more cases than the seven-case average; it has also recorded five deaths in a state that previously averaged one.
That makes the immediate takeaway straightforward for people planning to enter seawater: wounds need protection, and anyone with a medical condition that raises risk should treat the state’s warning as urgent rather than routine.
