Abstract

Background: Prisoners are at high risk of blood borne and sexually transmitted infections due to their high involvement in risky behaviors. In this descriptive/cross-sectional study, the prevalence, sero-prevalence, and risk factors for bloodborne tumor viruses including HTLV-I, HBV, HCV, and KSHV were evaluated among inmates of two central prisons in the northeast of Iran. Methods: Blood samples of 1114 inmates were analyzed for the presence of anti HTLV-I, KSHV, and HCV antibodies and HBsAg by ELISA. PCR tests were performed to confirm the presence of these viruses in plasma and identify the current infections. Results: The sero-prevalence of HCV, HBV, HTLV-I, and KSHV was 24.5%, 4.2%, 3.4%, and 3.2% and the prevalence of HCV, HBV, HTLVI, and KSHV was 19.1%, 2.1%, 2%, and 3%, respectively. HCV infection was significantly associated with history of imprisonment, tobacco consumption, alcohol consumption, intravenous drug use, length of imprisonment, and type of crime committed. Thirty one (2.8%) prisoners had HCV-KSHV co-infection, 16 (1.5%) had HCV-HTLV-I co-infection, and 14 (1.3%) had HBV-HCV co-infection. Triple co-infection was observed in seven cases and one case had four infections concomitantly. Conclusions: This epidemiological study indicated different rates and transmission risks for these viruses. HCV was the most contagious viral infection and HTLV-I was the weakest in the prisoners. Apart from KSHV infection which its prevalence was as twice as in the general population, the prevalence of HBV and HTLV-I in prisoners was nearly in ranges of the general population. © 2016, Kowsar Corp.
