Overview

• The Florida Department of Health has confirmed 11 infections and four deaths from Vibrio vulnificus by mid-July, prompting the updated advisory.
• The bacterium thrives in warm, brackish coastal waters and infects through open wounds or consumption of raw shellfish, especially oysters.
• Approximately half of Vibrio vulnificus bloodstream infections prove fatal and can lead to necrotizing fasciitis if untreated.
• People with weakened immune systems or chronic liver disease face a much higher risk of severe disease.
• Health officials advise avoiding saltwater contact with open wounds, steering clear of raw seafood, and wearing gloves when handling shellfish.
