Vibrio vulnificus infections carry about a 20% mortality rate even with treatment, with Louisiana and Mississippi coastal waters posing the main seasonal risk as temperatures rise.
Warm, salty or brackish water fuels algae growth that helps the bacteria thrive, and more than half of cases stem from water exposure through cuts, sores or other skin breaks.
Symptoms can escalate fast—swelling, redness, pain and fever can spread to an entire limb within 12 to 24 hours, with sepsis and organ failure often developing within 24 to 36 hours.
Raw seafood, especially oysters, can also transmit the bacteria, with people who have weakened immune systems, liver cirrhosis, cancer, transplants or immunosuppressive treatment facing the highest danger.
CDC estimates vibriosis causes 80,000 illnesses annually in the United States, and doctors urge rapid hospital care and early antibiotics if infection is suspected.
