The rate of HBV transmission to susceptible health
care workers ranges from 6% to 30% after a single needlestick exposure
to an HBV-infected patient [CDC 1997b].
Prospective studies of health care workers exposed
to Hepatitis C Virus through a needlestick or other percutaneous injury have found
that the incidence of anti-Hepatitis C Virus seroconversion (indicating infection)
averages 1.8% (range, 0% to 7%) per injury [Alter 1997; CDC 1998b].
To estimate the rate of HIV transmission, data were
combined from more than 20 worldwide prospective studies of health care
workers exposed to HIV-infected blood through a percutanous injury. In
all, 21 infections followed 6,498 exposures for an average transmission
rate of 0.3% per injury [Gerberding 1994; Ippolito et al. 1999].
