Transmission is from eating raw or undercooked shellfish, particularly oysters harvested from warm waters. Infections may occur when open soft tissue wounds are exposed to warm estuaries.
Persons with underlying medical conditions, any chronic condition especially liver disease and diabetes, may be at increased risk of serious infection. Infections are seasonal and 85% occur in the summer months. Transient environmental factors such as warm water and moderate salinity can increase the number of Vibrio vulnificus in shellfish.
Infection may occur in a pre-existing wound and cause soft tissue infection with severe pain or cause diarrhoea, vomiting and abdominal pain. Any of these symptom need medical attention.
