| Objective To investigate the infection situation of human immunodeficiency virus (HIV) in men who had sex with men (MSM) among the voluntary blood donors in Anyang area.Methods The blood samples of 440 474 voluntary blood donors in Anyang area, collected in our blood station from Jan 2008 to Dec 2015, were detected for anti-HIV primary screening and validation testing by means of enzyme-linked immunosorbent assay(ELISA) and Western blotting (WB). Based on the data of blood donors with HIV infection in the MSM group, the prevalence rate of HIV infection and infection situation in these donors of first and repeated donation were investigated and analyzed.Results Among the 440 474 voluntary blood donors, a total of 33 anti-HIV positive blood donors were found, with a prevalence rate of 0.007 5%, and among which 7 donors with HIV infection were MSM, accounting for 21.21%. As for the population structure characteristicsof 33 donors, cases of 18~29 years old accounted for 85.71%, cases with university degree accounted for 57.14%, cases of school students for 42.86%, and unmarried cases for 85.71%. The prevalence rate of HIV infection in each year showed an increasing trend and the differences among them were not significant (χ2=7.49, P>0.05). There were significant differences in the MSM HIV infection rate the blood donors of first higher repeated donation (χ2=8.54, P<0.05).Conclusion The overall HIV infection among those voluntary blood donors in Anyang area presents a steady, low prevalence tendency, and in the MSM population, the blood donors of first donation have higher HIV infection rate than those of repeated donation. |
