Update on vibrio vulnificus infections in Louisiana: 1977-2002.
Vibrio vulnificus is a human pathogen that resides naturally in
coastal waters where shellfish are harvested. This halophilic Gramnegative bacterium causes clinical syndromes that include
septicemia, wound infection, and gastroenteritis. Reportedly, 90% of
sea-food-associated deaths in the US are associated with V vulnificus
infections. In Louisiana, vibrio infections including V vulnificus have
been mandated as reportable since 1989. A retrospective descriptive
study of 233 cases of V vulnificus infections from 1977 through 2002 was
performed by the Louisiana Office of Public Health (Infectious Diseases
Epidemiology Section). V vulnificus infections reported in the state of
Louisiana were most commonly septicemia and wound infections (95% of all
cases). Seventy-five percent of all cases occurred in individuals
greater than 45 years of age (age range, 7-95 years), 85% were reported
in men, and infections by race were 10 times higher in whites than
African Americans. More than two thirds of these infections were
reported in individuals with a variety of underlying medical conditions
including liver disease, renal disease, diabetes, peptic ulcer disease and malignancy. The crude mortality rate for this cohort of patients was
25%. V vulnificus is a potentially life-threatening pathogen that
primarily causes the clinical syndromes of wound infection and
septicemia. Infections occur more commonly in middle-aged men with
underlying chronic medical conditions. These data provide additional
evidence about which populations would benefit from education regarding
the potential dangers of ingestion of raw shellfish or exposure of
wounds to contaminated shellfish or seawater.

I was totally shocked upon looking at the pictures of people infected by the Vibrio! I cant imagine how simple oysters can take your body parts away from you or your life as well.
