GBV-C: GB virus C, a virus first identified in 1995 that is genetically related to the hepatitis C virus but which does not cause hepatitis in humans. The exact role of GBV C in producing disease in humans remains unclear.
Infection with GB virus C (GBV-C) may be beneficial to HIV-infected patients. There are studies suggesting that these patients enjoy longer survival if they are coinfected with this virus and HIV than if they have HIV alone.
GB virus C (GBV-C) is also called hepatitis G. However, the designation GB virus C (GBV-C) is preferred because the virus is not a cause of hepatitis.
