Work presented in this report sought to assess the healthcare and economic burden of the hepatitis C virus (HCV) infection in the United Kingdom. It used a cohort simulation model to estimate the prevalence of HCV infection in the UK, including the number of persons who live with HCV infection at different disease stages, and the number of deaths that can be attributed to HCV infection through to 2035. It further assessed the healthcare and societal costs that are associated with HCV infection under different scenarios of diagnosis and treatment rates.
