Online conversations about flesh-eating bacteria in coastal waters have spiked as multiple states have reported cases. Although several species of bacteria are known to thrive in the Gulf Coast during warm months, cases have expanded to some northern states in recent years. Massachusetts issued an August 13 public health alert that a person in Cape Cod was infected by the rare Vibrio vulnificus, the most deadly of the flesh-eating bacteria currently affecting the U.S. Meanwhile, Louisiana has reported 20 Vibrio vulnificus infections and four deaths this year alone, roughly three times the annual average. While some social media users shared tips to avoid infection and how to spot early signs of an infection, others discussed the link between the bacteria and warmer waters due to climate change. Several posts promoted false or misleading claims, including that the bacteria were created in a lab and intentionally released in water and that activated charcoal and garlic can prevent infection.
Recommendation
Reports about Vibrio vulnificus in water may cause public alarm and fuel myths. Health communicators may use these conversations to share accurate information about the bacteria and how to avoid it. Messaging may explain that Vibrio vulnificus are rare and only live in salt or brackish (mix of salt and fresh) water. The bacteria enters the body through wounds, so people should avoid entering this type of water if they have cuts, scrapes, or recent piercings or tattoos. Additionally, the bacteria can spread through contact with raw or undercooked seafood. The CDC recommends thoroughly cooking all seafood and cleaning hands and other surfaces that come in contact with raw seafood.
