If you are a beachgoer in Florida, then beware that the water you’re swimming in contains a rare, but potentially fatal bacteria called Vibrio vulnificus. So far this year, nine people have been infected by the bacteria and three have died from it. Cases have been reported across six different counties.

Last year, Florida saw 32 cases of infection statewide and a total of seven reported deaths. So far, deaths have occurred in Brevard County, Marion County, and Hillsborough County. MORE
