Summary

This lecture by Professor Zach Murphy provides a comprehensive overview of Hepatitis C, focusing on recognition, diagnosis, and management. It begins with the etiology, highlighting that HCV is an enveloped, positive-sense single-stranded RNA virus. The key feature is its RNA-dependent RNA polymerase lacking proofreading activity, leading to high mutation rates and antigenic variation, which explains why the virus often becomes chronic. Transmission is primarily bloodborne, including IV drug use, needle sticks, and vertical transmission. The lifecycle is detailed, emphasizing the roles of NS3/4A protease, NS5A, and NS5B polymerase, which are targets for direct-acting antivirals. The clinical presentation covers acute hepatitis, often asymptomatic, with elevated AST/ALT and possible jaundice. Chronic infection occurs in 80% of cases, leading to fibrosis, cirrhosis, and hepatocellular carcinoma. Diagnosis involves antibody screening followed by confirmatory RNA testing. Treatment includes modern antiviral regimens with drugs like glecaprevir, velpatasvir, and sofosbuvir. Prevention focuses on harm reduction and screening, as no vaccine exists.
