Despite sensational headlines warning “millions” of impending peril, Louisiana health officials have issued a specific public warning regarding Vibrio vulnificus—commonly labeled “flesh-eating bacteria”—after nine cases and five deaths were recorded in the state this year.
While nine cases mark an uptick from Louisiana’s typical seasonal average of seven cases and one death, health department data reveals crucial context that panic-inducing titles gloss over:
- Risk factors: Every single person infected in Louisiana this year had pre-existing underlying health conditions and exposed an open wound to seawater.
- Transmission: The bacteria live naturally in warm coastal waters and enter the body through open cuts or via raw, undercooked seafood such as oysters.
- Seasonality: Bacteria populations naturally spike in warm water between May and October.
The infection can progress rapidly and cause severe illness. Health officials advise anyone with open wounds to stay out of salty or brackish water. If a wound exposed to seawater becomes red, swollen, unusually warm, or painful, seek immediate medical treatment and inform healthcare providers of the water exposure.
