Prisons are recognized worldwide as important sites for transmission of blood-borne viruses (BBVs). the high prevalence of HIV infection and drug dependence among prisoners, combined with the sharing of injecting drug equipment, make prisons a high-risk environment for the transmission of HIV and the lack of supply of preventive measures (such as sterile needle and syringes or condoms or methadone maintenance therapy). In most prisons of world, because of a variety of social conditions, extra opportunities for BBV transmission are created.
HIV prevalence in Iran is generally more than 8 times higher in prisons (1.75) than in general population estimation (0.2) because of the considerable over-representation of injecting drug users (IDUs) among prisoners. We want to study the trend and outcome of interventions of HIV/AIDS in IDU's prisoners of Iran during 1997-2007.
