Louisiana Reports Five Deaths from Vibrio vulnificus Infections in 2025

Louisiana health officials have reported a significant rise in Vibrio vulnificus infections in 2025, with 26 confirmed cases and five fatalities to date. This marks a substantial increase from the state's annual average of seven cases and one death over the past decade.

Vibrio vulnificus is a bacterium that thrives in warm coastal waters, particularly between May and October. Infections can occur through exposure of open wounds to seawater or by consuming raw or undercooked seafood, especially oysters.

The Louisiana Department of Health has noted that 85% of the reported cases involved wound exposure to seawater, and 92% of those infected had underlying health conditions.

Health officials are urging residents to take precautions, such as avoiding contact with brackish or salt water if they have open wounds, covering wounds with waterproof bandages, and ensuring seafood is thoroughly cooked before consumption.

The Centers for Disease Control and Prevention (CDC) reports that approximately one in five people infected with Vibrio vulnificus die, sometimes within a day or two of becoming ill.

Scientists have observed an increase in Vibrio infections, attributing the trend to rising sea surface temperatures associated with climate change.

Residents are advised to seek immediate medical attention if they develop symptoms such as fever, chills, redness, pain, swelling, or blistering skin lesions after exposure to coastal waters or consuming raw seafood.
