The Florida Health website states that a person can become infected with the bacteria after eating raw shellfish, namely oysters, or entering brackish seawater with an open wound. Brackish water occurs when freshwater mixes with ocean water—such as when a river meets the sea.
“Individuals who are immunocompromised, e.g chronic liver disease, kidney disease, or weakened immune system, should wear proper foot protection to prevent cuts and injury caused by rocks and shells on the beach,” Florida’s Health Department website states.
Some health officials called on people not to enter brackish water if they have fresh scrapes, cuts, or other skin abrasions.
“If you have wounds, maybe stay out of the water,” Dr. Shamas said. “If you suffer a cut while in the water, just wash it out very thoroughly with soap and water. Monitor your symptoms, and follow up with your doctor if you have any questions.”
According to the federal health agency, the bacteria can require intensive care or even limb amputations. And about 1 in 5 people with the infection die, sometimes within about 24 hours of contracting it.
“Cover your wound with a waterproof bandage if it could come into contact with saltwater, brackish water, or raw or undercooked seafood and its juices. This contact can happen during everyday activities, such as swimming, fishing, or walking on the beach. It could also happen when a hurricane or storm surge causes flooding,” the agency notes.
While anyone can contract the bacteria, the infection can be more severe in people with compromised immune systems. It can’t be transmitted from person to person, but individuals who are experiencing symptoms of the infection should seek medical attention as soon as possible, officials say.
Symptoms include watery diarrhea along with stomach cramping, nausea, vomiting, and fever. For infection of the bloodstream, symptoms include chills, fever, very low blood pressure, and skin lesions. And for a vibrio wound infection, symptoms include fever, pain, swelling, redness, discoloration, warmth, and discharge, according to the CDC.
“One patient reported consuming raw oysters from an out-of-state establishment. Two patients reported exposure to salt or brackish water in Long Island Sound. Both patients had pre-existing open cuts or wounds or sustained new wounds during these activities which likely led to the infections,” the agency stated in a news release.
A month before that, a 54-year-old Missouri man died after contracting the bacteria after eating raw oysters, NBC News reported.
