Hepatitis C Virus and Injection Drug Use
"Hepatitis C virus (HCV) infection is very common among injection drug users. Studies of injection drug users in regions with a longstanding pattern of endemic injection drug use have reported prevalences of HCV antibody in the range of 65% to 90%, even where HIV prevalence is quite low.1-5 The majority of HCV infections become chronic, resulting in a large reservoir of HCV infection among injection drug users. Incidence of HCV infection in previously uninfected injection drug users ranges from 10 to 30 per 100 person-years at risk."
