A new putative hepatitis virus has recently been discovered and termed GB virus C (GBV-C). We investigated the prevalence of this virus among 50 haemophiliacs treated with non-virus-inactivated clotting factor concentrates prior to 1985 and 21 haemophiliacs treated exclusively with virus-inactivated clotting factor concentrates. In the first group the prevalence of GBV-C based on PCR and ELISA was 46%. In the second group the prevalence of GBV-C was similar to that of healthy blood donors (5%). We therefore conclude that GBV-C is reliably inactivated by modern virucidal methods such as vapour heating, pasteurization and treatment with solvent/detergent mixtures.
