US Authorities Warn of Rising 'Flesh-Eating Bacteria' Infections

Health authorities in the United States have alerted the public to an increase in infections caused by Vibrio vulnificus, a dangerous bacterium commonly referred to as 'flesh-eating bacteria.' The infection, though relatively rare, carries a high mortality rate if not diagnosed and treated promptly.

This year, cases have emerged earlier than usual. Florida has confirmed five infections, with Connecticut reporting one case on the East Coast. Health officials on the West Coast are also monitoring the situation. Vibrio vulnificus naturally inhabits warm coastal waters. Infections commonly result from exposure of open wounds to contaminated seawater or from ingesting raw or undercooked shellfish, particularly oysters.

Symptoms usually appear within 24 hours and can include fever, chills, stomach cramps, and in severe cases, rapidly spreading tissue damage and painful blisters. If the bacteria enters the bloodstream, the infection can become aggressive, potentially leading to sepsis and death. Experts link the rise in infections to earlier warming of seawater due to climate change, creating ideal breeding conditions for the bacteria.

Medical professionals urge individuals, especially those with weakened immune systems, liver disease, or diabetes, to avoid consuming raw shellfish. They also advise covering any open wounds before entering the sea and thoroughly washing hands after handling raw seafood. While infections are uncommon, the potential for severe outcomes necessitates vigilance, particularly during the summer months when water temperatures are highest.
