Abstract Hepatitis C virus (HCV) genotypes vary greatly in different regions. The aim of this study is to investigate the distribution of HCV genotypes in HCV infected patients, in Ningxia Hui Autonomous Region. Nucleic acid extraction and amplification were performed with test kits on 153 HCV infected patients serum samples. The HCV viral load was measured using reverse transcriptase PCR (RT-PCR) and HCV genotypes were determined. Among the 153 HCV-infected patients, 56 had genotype (GT)1b (36.60%), 45 had GT2a (29.40%), 23 had GT3a (15.00%), 14 had GT3b (9.20%),13 had GT6a (8.50%), 1 had GT1g (0.70%), 1 had GT6xa (0.70%). In GT1b, 21.40% were female and 78.60% were male; in GT2a, 42.20% were female and 57.80% were male;Males were most prevalent in genotypes 1b(39.30%), while female were most prevalent in genotype 2a(46.30%). Rare GT1g and GT6xa were also detected in males. The 41-50 year age group had the highest HCV prevalence of 32.00%. HCV GT1b is the predominant HCV genotype in Ningxia Hui Autonomous Region.
