Foodborne Infections General: DBMD (Excerpt)

Vibrio vulnificus (General): DBMD (Excerpt)

Persons who are immunocompromised, especially those with chronic liver disease, are at risk for V. vulnificus when they eat raw seafood, particularly oysters. A recent study showed that people with these pre-existing medical conditions were 80 times more likely to develop V. vulnificus bloodstream infections than were healthy people. The bacterium is frequently isolated from oysters and other shellfish in warm coastal waters during the summer months. Since it is naturally found in warm marine waters, people with open wounds can be exposed to V. vulnificus through direct contact with seawater. There is no evidence for person-to-person transmission of V. vulnificus. (Source: excerpt from Vibrio vulnificus (General): DBMD)

Vibrio vulnificus: DBMD (Excerpt)

All persons. Persons with underlying medical conditions, especially liver disease, may be at increased risk of infection and serious complications. (Source: excerpt from Vibrio vulnificus: DBMD)

About risk factors:

Risk factors for Vibrio vulnificus are factors that do not seem to be a direct cause of the disease, but seem to be associated in some way. Having a risk factor for Vibrio vulnificus makes the chances of getting a condition higher but does not always lead to Vibrio vulnificus. Also, the absence of any risk factors or having a protective factor does not necessarily guard you against getting Vibrio vulnificus. For general information and a list of risk factors, see the risk center.
