ABSTRACT

Objective To investigate infection status and distribution characteristics of human immunodeficiency virus (HIV)infection among voluntary blood donors in Xiangyang area in 2009-2014,and provide evidence for re-cruiting blood donors from low-risk population. Methods Blood specimens of 326 856 voluntary blood donors in Xiangyang area between January 2009 and December 2014 were detected anti-HIV with enzyme linked immunosor-bent assay(ELISA),positive specimens in HIV screening were performed confirmatory testing,epidemiological analysis was conducted on the positive detection results.Results 41 (0.13‰ )voluntary blood donors were con-firmed positive for HIV in Xiangyang area,positive rate among each year was significantly different (χ2 =27 801.87,P<0.01). Except marital status and infection routes,difference in positive rates among donors of dif-ferent gender,age,area,occupation,educational attainments,and number of blood donation were all significantly different(all P<0.01). Among HIV-infected voluntary blood donors,87.80% were male,41.46% and 31.71%were aged between 18-25 and 36-45 respectively,56.10% were through heterosexual transmission,and 43.90%were through male homosexual transmission. The percentage of workman and public service personnel infected with HIV were high,accounting for 21 .95% and 17.07% respectively,60.97% of confirmed positive HIV were from city area,56.10% only received junior middle school/technical secondary school education,65.85% of HIV-infec-ted persons were infected at the initial donation.Conclusion In order to ensure blood safety,blood center should in-crease publicity efforts,carry out health consultation before blood donation,and recruit blood donors from low-risk populations,nucleic acid detection should be carried out to shorten HIV detection window period.
