This prospective observational study will investigate predictive values of virological response in peginterferon/ribavirin treatment-naive patients with chronic hepatitis C. Patients will be treated with Pegasys (peg-interferon alpha 2a) and Copegus (ribavirin) as prescribed by the physician. Data will be collected for 72 weeks.
