Detection of Hepatitis G Virus RNA in Persons with and without Known Risk Factors for Blood-Borne Viral Infections in Sweden and Honduras

We analyzed 224 and 163 serum samples from individuals in Sweden and Honduras, respectively, for the presence of the hepatitis G virus (HGV or GB virus-C) RNA. HGV infection in both Sweden and Honduras was related to common risk factors for blood-borne infections, despite a surprisingly high frequency in groups without known risk factors.
