The risk of hepatitis B infection among health professionals in the United States: a review.

Many physicians, dentists, and allied health personnel sustain occupational exposures to blood and other body fluids that increase their risk of contracting type B viral hepatitis. Overall, the risk of hepatitis B among persons employed in health-related fields is estimated to be approximately four times that in the general adult population. Studies on the incidence of infection and the prevalence of hepatitis B serologic markers have further defined risk in specific occupational categories and work activities. Physicians and dentists are five to ten times more likely than the general adult population to experience hepatitis B infection. Infection rates ten or more times above the average have often been characteristic of surgeons, patient care personnel in dialysis units and institutions for the mentally handicapped, and clinical laboratory workers having frequent contact with blood samples.
