So far in 2026, nine cases of Vibrio vulnificus have been reported among Louisiana residents. Vibrio infection can result in gastrointestinal illness, wound infection, or blood poisoning (bloodstream infection). Some species, including Vibrio vulnificus, can cause severe and life-threatening infections. About one in five people with Vibrio vulnificus infection dies, sometimes within a day or two of becoming ill. Starting this week, LDH will publish Vibrio vulnificus case data weekly on the Public Health Data Spotlight webpage.
