Overview
- State counts show an increase in severe Vibrio vulnificus cases this year with Louisiana reporting nine cases and five deaths and Florida reporting 14 cases and two deaths.
- Vibrio vulnificus causes fast-moving wound and bloodstream infections that can be deadly, and the CDC estimates about one in five infections result in death.
- The bacterium thrives in warm, salty or brackish water and experts cite higher water temperatures, nutrient-driven algal blooms and storm runoff as key drivers of recent increases.
- Health agencies have stepped up warnings and transparency with Louisiana issuing weekly public reports while researchers and agencies pursue satellite, AI and risk-mapping tools to predict hotspots.
- Clinicians and survivors warn of severe, lasting harm including amputations, so officials urge people to avoid coastal water with open wounds, cook shellfish thoroughly and wash wounds promptly after exposure.
