GB virus C

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