ABSTRACT

ObjectiveTo explore the epidemiologic features and distribution pattems of hepatitis C virus (HCV) genotype infection among HIV positive former blood donors (FBDs) and transfusion recipients in Hubei province.Methods597 serum samples from HIV-positive patients in Hubei were collected and examined for anti-HCV by enzyme-linked immunosorbent assay ( ELISA ).Reverse transcription nested polymerase chain reaction (RT-nested PCR) amplification and DNA sequencing were used to evaluate the HCV core regions.ResultsThe prevalence rates of HCV in HIV positive FBDs and transfusion recipients were 76.5％ (205/268) and 57.4％ (189/329) respectively.HCV genotypes 1b (92.8％,90/97) and 2a (7.2％,7/97 ) were detected.ConclusionsBlood donation and blood transfusion are the major modes of HIV-HCV co-infection in Hubei province.The prevalence of HCV in HIV positive transfusion recipients is lower than that in HIV positive FBDs.HCV genotypes 1b and 2a are the predominant strains among HIV-positive FBDs and transfusion recipients.
