Objectives: The aim of this study was to assess the prevalence of hepatitis C virus (HCV) markers, and risk factors of contamination in a prison population.
Patients and methods: Eight hundred and six prisoners were prospectively included, at the moment of their imprisonment, between December 1st 1995 and May 31st 1996. Each prisoner was included in a group "drug abusers" or "non drug abusers" based on a clinical examination. Serum anti-HCV antibodies were tested in each group. Other risk factors were also analysed (type of drug abuse, share of syringes and needles, blood transfusion, haemodialysis, and hemophilia).
Results: Among the 806 prisoners, 30.3% were anti-HCV positive. Four hundred and thirty nine prisoners (54.4%) were placed in the "drug abuser" group and 367 (45.5%) in the "non drug abuser" group. In the first group, 55.6% were anti-HCV positive (80% of the prisoners who were intravenous drug users and 10.8% for the others) and 4.2% were anti-HCV positive in the second group.
Conclusions: Half of the prisoners entering our center were drug abusers and half were anti-HCV antibody positive. HCV infection is a major public health problem in prison.
