[Hepatitis G virus: a new agent responsible for viral hepatitis].

Modern biology has allowed to detect a new hepatitis virus called G (HGV), joining an already important member of hepatitis viruses. Thus the share of viral hepatitis non A-non D decreases. The HGV belongs to the Flaviviridae and is similar to the HCV. Transmission occurs essentially by contaminated blood. There are still some open questions, particularly concerning the real pathogenic responsibility of the virus, which is far from clear considering latest publications. Further studies are necessary to precise epidemiologic data, ways of transmission, and pathogenic properties.
