Cross-sectional study of 668 injecting drug users recruited through respondent-driven sampling, inquired about demographic characteristics and risk behaviors. Laboratory testing was used on filter paper and cases of hepatitis C viral load tests with RNA were confirmed. Hepatitis C prevalence and associated factors was estimated with Chi-square test statistics and reasons for crude and adjusted prevalence were calculated using logistic regression.


The prevalence of hepatitis C was 17.5% and were found as factors that increase the prevalence of hepatitis: having HIV, injecting another person carrying the virus dose used was sharing a syringe, injected with a syringe and consume marijuana. As a factor that reduces the prevalence, purchase syringes in drug stores or other stores.
