Injection drug users (IDUs) face an increased risk of acquiring blood borne viral infections, including HIV and the hepatitis C virus (HCV). However, the discrepancy in funding for services to address these two diseases has implications. Although drug treatment programs have played an important role in fighting HIV/AIDS, the HCV-related services offered at these programs remain limited. Research from other countries suggests that drug users view HCV as less important than HIV, yet little is known about the extent to which our society's focus on HIV has been adopted within the drug treatment program culture. This qualitative study examines the perceptions of both staff (n = 165) and clients (n = 215) at these programs with regard to HIV and HCV and presents data on how staffs' attitudes toward HCV changed after participating in an HCV training. Clients described a services landscape at drug treatment programs that favors HIV services over those targeting HCV.
