Flesh-eating bacteria are devouring limbs in warming waters worldwide − here’s how to protect yourself

Flesh-eating bacteria, a potentially lethal threat, is spreading in warmer waters worldwide, including the U.S. Vibrio vulnificus, a bacterium thriving in warm seawater, is causing increasing concern among health officials. Louisiana has reported nine cases, including five deaths, while Florida has documented 14 cases, two of which resulted in fatalities.

Maryland has reported 72 cases. This deadly infection, necrotising fasciitis, can rapidly destroy underlying tissue, leading to amputations if left untreated. The bacteria, group A streptococcus or Vibrio vulnificus, primarily enter the body through open wounds or consumption of contaminated seafood. Rising ocean temperatures due to global warming are expanding the bacteria's habitat, allowing it to be found as far north as New York and Connecticut.

Climate change is also increasing the risk of severe infections among vulnerable populations, such as those with diabetes or weakened immune systems. Symptoms of infection include fever, redness, and intense pain, and early treatment is crucial to prevent rapid tissue destruction. Prevention measures include avoiding water contact with open wounds and not handling raw seafood while having a wound.
