[Phylodynamic of HCV Populations].

Hepatitis C virus is an actual public health problem worldwide since its discovering in 1989. It is explained not only by the wide spreading and frequent adverse outcomes of disease, the lack of effective preventive vaccine, but also by the high genetic variability of the virus. The current review summarizes the results of phylodynamic and phylogeographic studies of different HCV populations that allowed to characterize epidemic processes, to analyze the divergence of HCV into genotypes and subtypes, and to determine the geographic origin of the current HCV epidemic variants.
