    Abstract:
    OBJECTIVES: To determine whether infection with human immunodeficiency virus (HIV), hepatitis B virus (HBV) or hepatitis C virus (HCV) occurred after two potential episodes of exposure through needle- and syringe-sharing in Australian prisons, and to examine use of post-exposure prophylaxis (PEP) against HIV infection in the prison setting. DESIGN: Cohort study of potential contacts of two prisoners infected with HIV, HBV and HCV followed up for up to 14 months. SETTING: Two Australian prisons between November 2000 (time of exposure) and December 2001. PARTICIPANTS: Two index patients (both infected with HIV and HCV; one also infectious for HBV) from two different prisons, and 104 inmates who shared needles and syringes. MAIN OUTCOME MEASURES: Seroconversions to HIV, HBV and HCV related to the high-risk exposure and uptake and completion of HIV PEP determined from medical records of inmates. RESULTS: There were four seroconversions to HCV within 14 months of the potential exposure (14% of those susceptible in the cohort), but no recorded HIV or HBV seroconversions. Forty-six inmates (82% of those eligible) were offered PEP, and 34 of these (74%) elected to receive it. Only eight (24% of the 34) completed the full PEP course. CONCLUSIONS: HCV transmission in the prison setting is related to high-risk needle- and syringe-sharing. Administering HIV PEP in the prison setting is complicated by challenging risk assessment and follow-up.
