Treatment of hepatitis C virus infection with direct-acting antiviral agents: 100% cure?

Around 71 million people are chronically infected with HCV worldwide. HCV antiviral drug development has been remarkable. The availability of pangenotypic direct-acting antivirals with excellent efficacy and good tolerability profiles offer a unique opportunity to achieve HCV elimination worldwide. IFN-free DAA combinations can now cure HCV in more than 95% of patients with HCV infection after 8-12 weeks of treatment. Programmes to eliminate HCV must include increased screening (risk-based and universal), linkage to care, as well as increased access to treatment worldwide. In this paper, we will review the available data on recently approved direct-acting antiviral agents, with sustained virological response that reaches almost 100%.
