ABSTRACT: To determine the distribution of hepatitis C virus (HCV) genotypes in our population within the Basque country, 58 HCV-infected patients were analysed. The predominant HCV genotype among subjects infected by blood transfusions (n = 9) and surgical procedures (n = 14) was 1b (88 and 50%, respectively). On the other hand, genotype 3a was the most common among intravenous drug users (n = 16), with data statistically significant (p < 0.0001). There were 18 patients (31%) with unknown risk factors, twelve of whom (66.7%) were infected with genotype 1b. Patients infected with genotype 1b were older than patients infected with genotype 3a (p < 0.0001). There existed a relationship between the HCV genotype and the source of infection.
