Purpose
This study will define the substantial disease burden associated with viral hepatitis in India, and provide a foundation to understand the host and viral determinants of disease pathogenesis that may ultimately impact treatment decisions and outcome

Primary Outcome Measures:
- Variation in the IL28B rs12979860 SNP [ Time Frame: One Visit ]Characterize the variation in the IL28B rs12979860 SNP that exists among patients with chronic hepatitis C or chronic hepatitis B infection, in the different geographic regions of India
Secondary Outcome Measures:
- Prevelance of HBV and HCV genotypes [ Time Frame: One Visit ]Assess the prevalence of HBV and HCV genotypes and subtypes in different geographic regions of India
- Characterize the SNPs present in innate immune factors toll-like receptor 7 (TLR7) [ Time Frame: One Visit ]Characterize the SNPs present in innate immune factors TLR7 (rs3853839, rs179008); TLR9 (rs41308230, rs5743844 ); RIG-I (rs11795404, rs10813831) and NOD2 (rs2067085, rs2066842), in patients with chronic hepatitis C or chronic hepatitis B in the different geographic regions of India
Biospecimen Retention: Samples With DNA
A portion of the blood drawn at the study visits will be frozen and stored. Stored blood samples may be used by the Sponsor or its research partners for HCV/HBV genotyping/phenotyping assays (as applicable) or their development or for retesting the amount of HCV/HBV in the blood. At the conclusion of this study, these samples may be retained in storage by Gilead Sciences or a designee for a period up to 10 years

| Groups/Cohorts |
|---|
|
HCV Cohort
A total of 1000 subjects were enrolled in the study and of that 500 subjects had a diagnosis of chronic HCV infection

HBV Cohort
A total of 1000 subjects were enrolled in the study and of that 500 subjects had a diagnosis of chronic HBV infection

Detailed Description:
The overall goal of this study is to correlate the host and viral genetics of patients infected with viral hepatitis with their clinical presentation. This study will provide the first nation-wide estimate of key host genetic polymorphisms associated with immune response, such as in the IL28B gene locus which has been associated with treatment outcomes in hepatitis C. Characterization of HCV and HBV viral genotypes and sub-types across different geographic regions will allow for an exploration of associations between host and viral genotypes. Another objective of this study is to identify co-morbid illness and metabolic factors that are associated with chronic liver disease due to viral hepatitis. Finally, this survey will explore patient awareness of their disease, risk factors for disease progression, and their treatment options
