腸炎弧菌（又稱副溶血性弧菌）簡介 (Chinese fact sheet, PDF)
Vibrio are bacteria (germs) that cause an infection in the intestine. It is found naturally in saltwater and is common to the coastal waters in the United States and Canada. It is more common during summer months. For data on Vibrio in New York City visit EpiQuery .
Most people become infected by eating raw or undercooked shellfish (such as oysters, clams, mussels, lobster and crab). People can also get sick if cooked food comes in contact with the germ. This can happen when hands are not properly washed after touching raw shellfish, or if utensils and cutting boards used for raw shellfish are not washed properly after use. Less commonly, this germ can cause a skin infection if an open wound or broken skin comes in contact with seawater.
Vibrio can cause watery diarrhea, stomach cramps, nausea, vomiting, and fever. Usually these symptoms occur within 24 hours of exposure. Generally, people get sick for about 2 to 3 days and fully recover. Severe disease is rare and occurs more commonly in persons with weakened immune systems, such as those with HIV infection or people being treated for cancer.
It's hard to know exactly, because people who are mildly sick with the infection may not go to the doctor. In Asia, Vibrio is a common cause of foodborne disease. In the United States, it is less common.
Vibrio organisms can be found in stool (feces), wounds, or blood. A doctor should check for this infection with a special test if a patient has watery diarrhea and has eaten seafood, especially if raw or undercooked, or when a wound infection occurs after exposure to seawater.
Treatment is not usually necessary. It helps to drink plenty of liquids to replace fluids lost through diarrhea. In severe or prolonged illnesses, antibiotics can be used.
Vibrio occurs naturally in saltwater. When the appropriate conditions occur with regard to salt content and temperature, Vibrio thrives.
