This report describes the number of Hepatitis C Virus (HCV) registry Veterans in VHA care in 2015 based on serologic evidence of HCV infection status (HCV Positive) as well as the subset of those with VA laboratory evidence of HCV viremia (HCV Viremic). The difference between the HCV Positive and the HCV Viremic is the number of Veterans with a positive HCV antibody test who do not have VA laboratory documentation of a test for HCV viremia. For more information on data and methods see the HCV General Notes on this website and the Notes at the end of this report.
