The objective of the study is to determine the safety of DAA's among chronic HCV patients. The outcomes of the study are; To determine the frequency of adverse events while receiving DAAs with or without RBV and/or Pegylated Interferon To calculate the percentage of patients with severity of medical event as per Karch and Lasagna classification To determine the percentage of patient having serious adverse event as per ICH Classification

Seriousness of adverse event will also be recorded as per the ICH classification and severity of medical event will be assessed as per Karch and Lasagna classification.

All the information will be recorded by the healthcare professionals on the questionnaire during direct interaction with the patients.
