A new case of the flesh-eating bacteria Vibrio vulnificus has been confirmed in Cape Cod, Massachusetts, highlighting concerns about rising cases along the US east coast. The bacteria thrives in warm waters and can cause severe illness, including necrotizing fasciitis.
As of July 30, Louisiana reported 17 cases, with four deaths, mostly linked to “wound/seawater exposure.” In contrast, during the last decade, Louisiana averaged seven cases and one death per year. Florida also reported 13 cases with four deaths as of July 24.
Massachusetts has seen 71 confirmed and probable cases of Vibrio, including all types, with hospitalization rates at 30%. This is a significant increase from the average 88 cases per year from 2015 to 2024.
Experts attribute the rise in cases to climate change, which causes warming ocean temperatures. To minimize risk, individuals are advised to avoid swimming or entering water with open wounds, cover wounds with waterproof bandages, and seek medical care promptly if symptoms occur after seawater exposure.
People can get Vibrio vulnificus by swimming with open wounds or eating undercooked seafood, such as raw oysters. Immunocompromised individuals and those taking certain medications are more at risk of severe disease.
