Tailoring response-based treatment for hepatitis C

The recommended treatment for chronic infection with hepatitis C virus (HCV) is a combination of pegylated interferon (pegIFN) alfa and ribavirin (RBV). Treatment duration is determined by HCV genotype: in genotype 1 (G1) infection, treatment usually lasts for 48 weeks, whereas in genotypes 2 and 3 (G2, G3), therapy for 24 weeks has been found to have equivalent efficacy.
