# Three Vibrio bacteria cases reported in SC; one related death

> SC health officials reported three cases of Vibrio vulnificus this year, including one related death, as warmer coastal waters raise infection risk.

South Carolina health officials have reported three cases of Vibrio vulnificus, a potentially deadly bacterium found in coastal waters and seafood, and are aware of one related death this year.

Vibrio vulnificus lives naturally in warm coastal waters, including brackish mixes of saltwater and freshwater, and turns up more frequently during the summer and early fall. People can contract it two main ways: by entering the water with an open wound, cut or sore, or by eating raw or undercooked seafood, particularly oysters. Infection can cause gastrointestinal illness, severe skin infections and death. About one in five people who develop a severe bloodstream infection from Vibrio vulnificus die, in some cases within a day or two of becoming ill. The actual annual death count in South Carolina is unknown because Vibrio deaths are not required to be reported.

State environmental officials do not routinely monitor coastal waters for Vibrio, describing it as one of many pathogens that occur naturally in ambient water bodies. Reducing risk starts at the water and the kitchen: avoid entering the ocean or brackish rivers with open wounds; skip water activities if immune systems are compromised; and cook seafood thoroughly. Guidance from state public health calls for boiling shellfish in the shell until the shells open and then continuing to boil for five more minutes; steaming until shells open and continuing another nine minutes; boiling shucked oysters at least three minutes; frying at 375 degrees for three minutes; broiling three inches from the heat for three minutes; or baking at 450 degrees for 10 minutes. Fish should reach an internal temperature of 145 degrees or flake easily with a fork.

The three reported cases this year, from a Conway-datelined coastal-area report, come as warm-water bacteria remain an intermittent concern along the South Carolina coast. Anyone who develops a rapidly worsening skin infection after saltwater exposure, or gastrointestinal symptoms after eating raw shellfish, should seek medical care promptly and inform the provider of the exposure so appropriate testing and treatment can begin.
