Health officials urge caution for Gulf Coast beachgoers during surge of deadly bacterial infections
PBS • • general
Key Points:
- Louisiana has reported nine cases of Vibrio vulnificus infections this year, with five deaths, marking an increase compared to the average of seven cases and one death annually over the past decade.
- Vibrio vulnificus bacteria thrive in warm, salty coastal waters, particularly in the Gulf Coast region, and infections commonly occur from May to October.
- The bacteria can enter the body through cuts or breaks in the skin exposed to seawater or brackish water, and severe infections are more common among the elderly, immunocompromised individuals, and those with chronic illnesses.
- Climate change is contributing to the spread and increased incidence of Vibrio infections, with cases moving northward by about 30 miles annually.
- Health officials advise beachgoers to thoroughly wash any wounds exposed to coastal waters, avoid eating raw or undercooked shellfish, and seek immediate medical care if symptoms such as fever, chills, or skin discoloration develop.
