A review of the discovery of the GB viruses (GB virus-A, GB virus-B and GB virus-C) is presented, and the relationship between the GB virus-C and the hepatitis G virus (HGV) is mentioned. The GB virus-A and GB virus-B apparently do not cause liver disease in human. The GB virus C, HGV or GBV-C/HGV is transmitted parenterally, usually through blood transfusions or contaminated needles causing chronical infection. The prevalence of GBV-C/HGV infection among volunteer blood donors is less than 1%, and in patients with C or B hepatitis is more than 10%; the pathogenicity of this agent is not well defined. |
