hepatitis C virus genotype


Definition: genetic heterogeneity and divergence in the viral sequences produce at least six genotypes of HCV. Genotypes cluster geographically (e.g., genotypes 1a and 1b typically found in the United States and Europe, genotype 4 in Africa and the Middle East, genotypes 5 and 6 in Southeast Asia and South Africa). Response to interferon therapy depends on HCV genotype.
