Gulf Coast Urged to Watch for Deadly Vibrio Bacteria in Warm Waters
Health officials warn that Vibrio vulnificus, a bacteria thriving in warm, brackish Gulf waters, can cause severe illness from contaminated shellfish (often raw oysters) or exposed wounds and can progress rapidly to bloodstream infection, especially in people with liver disease or weakened immunity. Florida has 14 cases and 2 deaths, Louisiana 9 cases and 5 deaths so far this year. Warning signs include worsening pain, redness, swelling, fever, discharge or blistering; seek medical care urgently. Treatment typically involves antibiotics, sometimes IV antibiotics and sepsis care. Prevention includes thorough shellfish cooking and avoiding seawater exposure with wounds. The CDC advises prompt treatment if Vibrio infection is suspected; warmer water, flooding, and major weather events can raise Vibrio levels along the Gulf.
