Being an orphan virus despite a large number of investigations, hepatitis G virus is a blood-borne agent for which screening is not required in blood donations. The in vivo efficacy of pathogen inactivation methods could be assessed by the absence of hepatitis G virus markers after transfusion of pathogen-inactivated blood products, in recipients susceptible to infection before the transfusion.
