[Viral hepatitis C]

This review is indicative of a considerable progress in the study of viral hepatitis C: HCV biology (its structural and antigenic analysis, genotype heterogenicity and genome mutation, mechanisms of replication), serological diagnosis, epidemiology, pathogenesis and clinico-morphological characteristics of liver involvement, systemic manifestations as well as carcinogenesis in HCV contamination. There exist data in favour of HCV role in a wide spectrum of pathology in parallel to what was earlier established in relation to HCV.
