This document provides information about viral hepatitis, focusing on hepatitis A, B, and C. It discusses the transmission, symptoms, diagnosis, and long-term effects of each virus. Hepatitis A and B can be prevented through vaccines, while hepatitis C has no vaccine and is transmitted through blood. Over time, untreated hepatitis C can lead to cirrhosis or liver cancer, though many people have no symptoms for decades. Genotypes determine treatment options for hepatitis C.
