Hepatitis C virus (HCV) infection is present in an estimated 150–200 million people worldwide and HCV is hyper-endemic among people who inject drugs (PWID).  In addition, outbreaks of HCV have recently occurred among HIV-positive men who have sex with men (MSM) and in adolescents and young adults who have transitioned from prescription opiate misuse to drug injection. In patients with chronic HCV infection, 20-25% will develop liver disease which may manifest as cirrhosis, liver failure or hepatocellular carcinoma (HCC), the most common type of liver cancer. The study estimated the effects of prevention and treatment interventions, alone and in combination, on the HCV disease burden in PWID and HIV+MSM. The results of the study will be used to guide public health policy and resource allocation to control HCV infection in the US and other countries.
