To the Editor: We recently used a modelling approach to describe how the burden of infection with hepatitis C virus (HCV) and the associated health care costs in Australia will increase as the infected population ages.1 We showed that increasing the efficacy of antiviral therapy and the number of patients treated could avert the expected increase in deaths from HCV-related liver disease and in the number of patients with end stage HCV-related liver disease. We did not include the specific costs of new direct-acting antiviral (DAA) regimens, as these are yet to be determined in Australia. We know that the cost of the new regimens has elicited discussion internationally about the ability of payers to meet those costs.
