Vibrio vulnificus is highly toxic, with an average incubation period of 24 hours. About 50% to 70% of patients will experience local skin swelling and obvious pain within one or two days, and the skin around the wound or at the end of the infected limb will turn black and purple with blisters. Infected people often have symptoms such as fever, abdominal pain, diarrhea, vomiting, and hypotension. The disease progresses rapidly. If not treated in time, severe cases may develop into muscle necrosis and sepsis, and even risk amputation and multiple organ failure. How to avoid infection with Vibrio vulnificus? ❗Eat less raw or cold seafood, and try to cook seafood before eating. ❗ Avoid getting injured in seawater or exposing existing skin wounds to seawater. ❗ It is best to wear gloves when washing seafood. Once you are stabbed by crab legs, shrimp spines, etc., rinse the wound with clean water in time and disinfect it with alcohol. ❗ Avoid exposing open wounds or broken skin to warm, salty waters or waters where shellfish are harvested.
