Vibrio vulnificus: Risk, transmission, disease and prevention
Most people get vibriosis by eating raw or undercooked shellfish, particularly oysters. Some people get vibriosis after an open wound comes in contact with coastal waters.
Ingestion of Vibrio vulnificus can cause vomiting, diarrhea and abdominal pain. Vibrio vulnificus can also cause an infection of the skin when open wounds are exposed to warm seawater; these infections may lead to skin breakdown and ulcers.
Vibrio vulnificus bloodstream infections are fatal about 50% of the time. A recent study showed that people with these pre-existing medical conditions were 80 times more likely to develop Vibrio vulnificus bloodstream infections than healthy people.
