Massachusetts health officials issued a warning about Vibrio bacteria in coastal waters after a rare infection case. The individual likely contracted Vibrio vulnificus at a Buzzards Bay beach. Warm water temperatures increase Vibrio growth, making May-October peak season. Symptoms range from gastrointestinal issues to potentially life-threatening necrotizing fasciitis ("flesh-eating disease"). About 20% of Vibrio vulnificus infections are fatal. The state has seen only seven confirmed cases in recent years.
