Recently, the isolation of a novel virus, GB virus C (GBV-C), associated with cryptogenic hepatitis has been reported. Following the molecular cloning of this virus genome, it became apparent that the genomic sequence did not encode a protein resembling a nucleocapsid or core-like protein similar to those observed in other flaviviruses, pestiviruses, hepatitis C virus (HCV) and GB virus B. Simi...

Heavy goods vehicle (HGV) driving is recognised as a highly hazardous occupation due to the long periods of sedentary behaviour, low levels physical activity and unhealthy food options when working. These risk factors combine with shift work concomitant irregular sleep patterns increase prevalence fatigue. Fatigue closely linked stress and, subsequently, poor physiological psychological health....

7 Abstract: There are, at least, five different hepatitis viruses (HAV to HEV) that primarily target the liver in humans, whereas the role of sixth virus (HGV) is doubtful. Although symptoms produced are similar, these viruses differ greatly in their structure, mode of replication and transmission, thus requiring altogether different control/ approach strategy. An attempt is made to review in b...

The role of viral superinfection in hepatitis B surface antigen carriers with superimposed fulminant (n = 60) versus nonfulminant (n = 90) acute hepatitis was studied. The frequency of hepatitis A virus (HAV) (0 versus 2.2%), HCV (18.3 versus 21.1%), HDV (15.0 versus 7.8%), and HEV (1.7 versus 4.4%) infection showed no significant difference, while simultaneous HCV and HDV infection was signifi...
