Vibriosis is an illness caused by the Vibrio bacteria species. Illness often occurs from eating raw or undercooked shellfish or by exposing a wound to seawater. Vibrio occurs naturally in saltwater coastal environments and can be found in higher concentrations from May to October when the weather is warmer. Infection with vibriosis can cause a range of symptoms such as diarrhea, stomach cramps, and vomiting, fever, chills, ear infections and wound infections. It is estimated that 80,000 people become infected, resulting in about 500 hospitalizations and 100 deaths in the United States per year.
