GB VIRUS C (GBV-C)

GB virus C (GBV-C) is a species of virus in the Flaviviridae family which has not yet been assigned to a 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

History

Hepatitis G virus and GB virus C (GBV-C) are RNA viruses that were independently identified in 1995, and were subsequently found to be two isolates of the same virus.
Although GBV-C was initially thought to be associated with chronic hepatitis, extensive investigation failed to identify any association between this virus and any clinical illness.

Taxonomy

GBV-C is a member of the Flaviviridae family and is phylogenetically related to hepatitis C virus but appears to replicate primarily in lymphocytes, and poorly if at all in hepatocytes.
GBV-A and GBV-B are probably Tamarin viruses, while GBV-C infects humans.

Human infection

The majority of immune-competent individuals appear to clear GBV-C viraemia within the first few years following infection and although the time interval between GBV-C infection and clearance of viraemia (detection of GBV-C RNA in plasma) is not known, infection may persist for decades in some individuals.
Approximately 2% of healthy US blood donors are viraemic with GBV-C, and up to 13% of blood donors have antibodies to E2 protein, indicating prior infection.
Parenteral, sexual and vertical transmission of GBV-C have all been documented, and because of shared modes of transmission, individuals infected with HIV are commonly co-infected with GBV-C. Among people with HIV infection, the prevalence of GBV-C viraemia ranges from 14 to 43%.
Some studies have suggested that co-infection with GBV-C will actually slow the progression of HIV disease.

Thanks for the update.There is so much to gather about the dangerous HIV and I am glad to see that there is some help regarding the same.

I was diagnosed as HEPATITIS B carrier in 2013 with fibrosis of the
liver already present. I started on antiviral medications which
reduced the viral load initially. After a couple of years the virus
became resistant. I started on HEPATITIS B Herbal treatment from
ULTIMATE LIFE CLINIC (www.ultimatelifeclinic.com) in March, 2020. Their
treatment totally reversed the virus. I did another blood test after
the 6 months long treatment and tested negative to the virus. Amazing
treatment! This treatment is a breakthrough for all HBV carriers.
