Retrospective comparative study on hepatitis C virus (HCV) genotypic patterns: Drug-related versus non-drug-related HCV

Background: Hepatitis C virus (HCV) remains a global health challenge, with genotype distribution influencing disease progression and treatment outcomes. In India, genotype 3a predominates and is linked to accelerated fibrosis and hepatocellular carcinoma. Intravenous drug use (IVDU) is a major driver of transmission, though transfusion, occupational exposure, and comorbidities remain relevant. Aims and Objectives: This retrospective study compared demographic, genotypic, and clinical features o
