ICYMI: Vibrio Vulnificus Death Toll Up to 7

The number of people who have died in Florida due to Vibrio vulnificus bacteria has climbed to seven.

The latest fatal cases were reported in Sarasota and Duval counties. The Florida Department of Health has a running tally of cases on its website. As of Tuesday – the latest update – the total number of cases this year had climbed to 13 with the seven deaths included.

The source of exposure in Sarasota County is unclear, said Mara Burger, press secretary for the department of health. The Duval County case, however, was linked back to consumption of raw oysters, Burger told Patch.

The 13 cases have primarily been reported along the east coast, but Pasco and Hillsborough counties have also witnessed cases 2015 so far. The Pasco case did not result in death, but Hillsborough has logged two deaths so far in 2015. Hillsborough’s first death involved a man who was exposed to the bacteria while in Mississippi, Burger said. The second death involved seawater exposure.

“Vibrio vulnificus is a bacterium that normally lives in warm seawater,” Burger explained. “Vibrio vulnificus infections are rare.”

Burger said people can get infected with Vibrio vulnificus in one of two ways – by eating contaminated raw shellfish or through exposure to contaminated water by swimming with open wounds.

Burger stresses the bacteria doesn’t pose risks for normally healthy people who don’t “have open cuts or wounds” who swim in Florida’s salt or brackish waters.

Vibrio vulnificus is often called the “flesh-eating” bacteria, but that’s not an entirely accurate label, Burger said. Most people who come into contact with the bacteria don’t show severe symptoms. Signs of exposure in normally healthy people include such symptoms as stomach cramps, diarrhea and vomiting.

The U.S. Centers for Disease Control and Prevention explains on its website that consumption of contaminated shellfish or open-wound exposure among immunocompromised people, “particularly those with chronic liver disease can infect the bloodstream, causing a severe and life-threatening illness characterized by fever and chills, decreased blood pressure, and blistering skin lesions.”

When open wounds come in contact with Vibrio vulnificus, the CDC says infections that arise “may lead to skin breakdown and ulceration.” When that breakdown of skin tissue occurs, it’s caused by a serious complication, known as Necrotizing Fasciitis. It’s that complication that gives rise to the “flesh-eating” moniker.

”Necrotizing Fasciitis is a rare disease that can be caused by more than one type of bacteria,” Burger said. “These include group A Streptococcus (group A strep), Klebsiella, Clostridium, Escherichia coli, Staphylococcus aureus and Aeromonas hydrophila, among others. Group A strep is considered the most common cause of necrotizing fasciitis. Vibrio vulnificus and Necrotizing Fasciitis are not one in the same.”

A number of Vibrio vulnificus cases were reported across the state in 2014. Seven deaths in total were blamed on the bacteria.
