Hepatitis G
Hepatitis G (HGV) is an enveloped RNA virus.
It is more prevalent than HCV with 2% of US blood donors testing positive for this disease.
According to the Canadian Hepatitis Information Network, this blood-borne pathogen is often transmitted at the same time as HCV.
There is currently no vaccine for this type of hepatitis.
The medical profession has not yet reached a consensus on how much of a threat, if any, this recently discovered virus poses to humans.
Despite the high frequency and incomplete knowledge about the virus, the $200.00 price tag to test for HGV is usually considered an unjustified expense even for donor blood.
HGV lowers the response to treatment for HCV by 6%.
