The first NS3/4A hepatitis C virus (HCV) protease inhibitors telaprevir and boceprevir were approved in 2011, and both NS5A and NS5B polymerase inhibitors were launched. Recently, direct-acting antivirals (DAAs) have had a major impact on patients infected with HCV. HCV DAAs are highly effective antivirals with fewer side effects. DAAs have been developed for the treatment of HCV infection in combination with PEG-IFN-α/RBV as well as in IFN-free regimens. However, some drug resistance mutations occur when a single oral DAA is used for treatment, which indicates that there is a low-frequency drug resistance mutation in HCV patients before the application of antiviral drugs. Our research showed that natural resistance to HCV DAAs was found in treatment-naive CHC patients and that the drug resistance mutation rates differ in various HCV genotypes. Many challenges posed by natural resistance should be considered in the context of DAA therapies.
