The Louisiana Department of Health (LDH) says the state has recorded nine cases of Vibrio vulnificus infection so far in 2026, and every single one of those patients ended up hospitalized.

Severe wound infections can progress to necrotizing fasciitis, and in the worst cases, doctors have to amputate to stop the infection from spreading further.

For now, the message from health officials is simple, if not exactly comforting: the bacteria has always been in Gulf waters.
