[Occupational medicine significance of hepatitis C in health care employees]

Abstract

Transmission of Hepatitis C virus (HCV) is similar to the one observed with hepatitis B virus. The most important route of infection in health care personnel is by needlestick injury. In the course of a literature review 44 publications on HCV prevalence or incidence among hospital employees were studied and an overall transmission incidence of 2.2% was found. As none of the publications dealt with the problem of chronic Hepatitis C, 245 persons with elevated transaminases occupied Freiburg University Hospital were tested for HCV antibodies. 3 out of 82 non-medical professionals and 19 out of 163 health care workers were anti HCV positive (RR = 3.22; p < 0.05). Charwomen in medical departments, nurses and dentists had a higher relative risk than physicians and technical assistants. As no HCV vaccine is available the only way of HCV-prevention is compliance with universal precautions.
