Core Tip

Core tip: Understanding the general properties of hepatitis C virus (HCV) viral RNA and proteins facilitates the development of sensitive diagnostic tools and effective antiviral treatments. At present, serologic screening test is recommended to perform on individuals in the high risk groups and nucleic acid tests are recommended to confirm the active HCV infections. To 2014, in addition to pegylated interferon and ribavirin, boceprevir, telaprevir, simeprevir, sofosbuvir and Harvoni are approved by Food and Drug Administration to treat HCV infections. The majority of HCV infections can be cured by these anti-viral treatments. An efficient prophylactic vaccine will be the next challenge in the fight against HCV infection.
