Current genoprevalence in hemophilia patients co-infected with HIV/HCV. (A) The proportion of HCV RNA-positive and -negative hemophilia patients co-infected with HIV/HCV. A phylogenetic tree of the HCV core region from 17 hemophilia patients co-infected with HIV/HCV was constructed. (B) Six patients were classified as genotype 1a (cases 1, 9, 31, 39, 44, and 45), six as genotype 1b (cases 4, 12, 19, 22, 40, and 43), and five as genotype 3a (cases 23, 29, 32, 38, and 42). (C) The proportion of HCV genotypes in 21 hemophilia patients co-infected HIV/HCV and positive for HCV RNA. HIV, human immunodeficiency virus; HCV, hepatitis C virus.
