What is the incubation period for Vibrio?
The incubation period for vibriosis ranges from 4–96 hours (72 maximum for V. vulnificus), usually 12–24 hours. Since Vibrio infection is not considered to be transmissible person-to-person, there is no carrier state and no defined period of communicability.

How can I test my Vibrio?
Isolation and identification of Vibrio cholerae serogroup O1 or O139 by culture of a stool specimen remains the gold standard for the laboratory diagnosis of cholera. Cary Blair media is ideal for transport, and the selective thiosulfate–citrate–bile salts agar (TCBS) is ideal for isolation and identification.
How long does Vibrio cholerae last?
The symptoms of mild or uncomplicated cases of cholera resolve on their own (spontaneously) within 3 to 6 days of onset. The bacteria usually disappear from the gastrointestinal system within 2 weeks. Most people with cholera require the replacement of fluids that are lost due to prolonged diarrhea.
How can you tell if you have Vibrio?
Signs and symptoms of Vibrio vulnificus infection can include:
- Watery diarrhea, often accompanied by stomach cramping, nausea, vomiting, and fever.
- For bloodstream infection: fever, chills, dangerously low blood pressure, and blistering skin lesions.
What is the duration of the symptoms of Vibrio vulnificus?
When ingested, Vibrio bacteria can cause watery diarrhea, often accompanied by abdominal cramping, nausea, vomiting, fever, and chills. Usually these symptoms occur within 24 hours of ingestion and last about 3 days. Severe illness is rare and typically occurs in people with a weakened immune system.
How long does Vibrio parahaemolyticus last?
Illness typically lasts 1 to 7 days. Treatment is not necessary in most cases. Severe illness is rare and occurs most often in persons with weakened immune systems.
How long does diarrhea last from Vibrio?
Symptoms usually last about 3 days, and most people recover without treatment. People with vibriosis should drink plenty of liquids to replace fluids lost through diarrhea.
