[Risk of hepatitis C virus infection by needlestick among medical employees]

We have experienced 99 medical employees who had stuck themselves by the needles used by patients in the past 5 years. Sixteen of the 99 cases (16.2%) were of the patients who had hepatitis C Virus (HCV) antibodies. We followed up these 16 medical employees during 24.8 +/- 12.0 months. We could not find any case among them who had seroconverted HCV antibody positive in their serums. We concluded that the risk of HCV infection by the needlestick accident is not so high.
