GB virus C

GB virus C (GBV-C), formerly known as hepatitis G virus (HGV) and also known as human pegivirus (HPgV), is a virus in the family Flaviviridae and a member of the Pegivirus. It is known to infect humans but is not known to cause human disease. Reportedly, HIV patients coinfected with GBV-C can survive longer than those without GBV-C, but the patients may be different in other ways. Research is active into the virus' effects on the immune system in patients coinfected with GBV-C and HIV.
