Figure 2 Algorithm of hepatitis C virus testing in the two female populations. Monolisa hepatitis C virus (HCV) (initial): Samples tested initially with Monolisa and results observed; Monolisa HCV (triplicate): Samples positive with initial test and found at least once positive in two additional replicates (step of duplicate is not represented here); INNO-LIA HCV: Monolisa positive samples analyzed by INNO-LIA HCV confirmation test; PCR HCV: INNO-LIA HCV tested samples further analyzed by polymerase chain reaction (PCR); Genotyping: Positive PCR samples analyzed for genotype determination; ind: Doubtful result from Monolisa test; IND: Indeterminate result from INNO-LIA HCV confirmation test; Geno 1b: HCV-1 subtype b genotype; Geno 2: HCV-2 genotype.

Figure 3 Prevalences of human immunodeficiency virus and hepatitis C virus compared according to age. Human immunodeficiency virus (HIV) < 50 years old: Young women with HIV infection; HIV > 50 years old: Older women with HIV infection; Hepatitis C virus (HCV) < 50 years old: Young women with HCV infection; HCV > 50 years old: Older women with HCV infection; HCVG1: HCV genotype 1; HCVG2: HCV genotype 2; %: Prevalence.
