: "The World Health Organization estimates that 3% of the global population has been infected with HCV, translating to >170 million chronically infected persons at risk of progression to cirrhosis and/or hepatocellular carcinoma. HCV exhibits extensive genetic diversity; six major genotypes and dozens of subtypes have been distinguished. Viral genotyping studies should be performed as a prerequisite to treatment initiation since genotype data guide selection of an optimal therapeutic regimen. Clinicians rely on knowledge of HCV genotype for choosing a therapeutic management strategy that maximizes probability of cure while minimizing adverse effects of antiviral medications.
