Incidence And Prevalence Of Human Immunodeficiency Virus, Hepatitis B Virus, Hepatitis C Virus, And Cytomegalovirus Among Health Care Personnel At Risk For Blood Exposure: Final Report From A Longitudinal Study

摘要: In a 10-year dynamic cohort study, 976 health care providers were followed mean of 1.9 years to evaluate the risk human immunodeficiency virus (HIV) transmission, delayed seroconversion, and seronegative latent infection following occupational exposures. The seroprevalence incidence HIV, hepatitis B (HBV), C (HCV), cytomegalovirus (CMV) also measured, with annual serologic testing for viruses postexposure HIV tests. One 327 percutaneous exposures (0.31%; confidence interval, 0.008%-1.69%) 0 398 mucocutaneous HIV-infected blood transmitted HIV. Neither seroconversions nor infections detected. baseline seroprevalences HBV, HCV, CMV 21.7%, 0, 1.4%, 43.4%, respectively. Corresponding density rates 3.05, 0.055, 0.08, 2.48 (per 100 person-years). Despite control precautions availability vaccine, these remain at acquiring bloodborne viral infections.
