A new genotype 2 subcluster identified among GBV-C strains circulating in the Lisbon metropolitan area of Portugal

The rate of infection by the GBV-C virus was investigated in a group of 214 individuals at high risk of infection with parenterally transmitted viruses, and all living in the Lisbon metropolitan area (Portugal). RNA was extracted from plasma samples, and a fragment of the 5′-UTR was amplified by RT-PCR, disclosing a high prevalence of infection (40.7%).

Hepatitis C virus subtypes circulating among intravenous drug users in Lisbon, Portugal.

Hepatitis C virus (HCV) infects 2-3% of the world population and intravenous drug consumption is the leading cause of transmission in industrialized countries. The unavailability of data on the molecular epidemiology of HCV infection in Portugal prompted the study of HCV subtypes circulating among intravenous drug users residing in the Lisbon metropolitan area and sampled about 10 years apart (1998-2000 and 2008-2009).
