                            Background:            Viral co-infection is a   major cause of human mortality and morbidity and diagnosis of infected   patients can lead to prevalence reduction.             Methods:         In a cross-sectional study,   106 HIV positive patients with a history of IVDA, addmitted among 2000-2007   to Navab-Safavi curing center in Isfahan,   were studied.    HBs Ag and HCV-Ab were   carried on by ELISA method and check-list of related risk factors was   completed for each patient. The prevalence of hepatitis B and C and related   risk factors were analyzed using Odds Ratio (95% CIs) and logistic Regression   tests.             Findings:         Our result showed that   2 patients (1.8%) had hepatitis B, 80 patients (75.5%) had hepatitis C and 10   patients (9.4%) had both of them. History of imprisonment and unemployment   were independent risk factors for IVDA [OR (95% CIs): 18.27 (5.9-56.5) and 8   (2.4-26.1) respectively] but marital status, education and age have not any   correlation with neither IVDA nor hepatitis.             Conclusion:         Our results indicated   high prevalence of hepatitis B and C in HIV positive patients with IVDA   history. Unemployment and low hygiene in prisons must be mentioned to reduce   IVDA in our society.             Key words:         HIV, HBV, HCV, Risk factors, IVDA.
