目的核实2007年后艾滋病(AIDS)综合防治信息系统中报告的采供血途径感染人类免疫缺陷病毒(HIV)者的信息,了解其真实感染途径。方法选择河南省、安徽省的4个县,对艾滋病综合防治信息系统中,2007年1月1日至2010年7月31日报告的、经采供血途径感染HIV的病例,问卷调查其确诊HIV阳性前的高危行为暴露史、既往HIV抗体检测史、确诊时病程状态,综合以上信息重新判断研究对象可能的感染途径。结果调查收回有效问卷410份,核实后,357例研究对象为经采供血途径感染HIV,53例为经非采供血途径感染。经统计学检验,研究对象中,采供血途径与非采供血途径感染HIV的两组人群,在年龄、性别、病程状态的构成上无统计学差异。53例重新判断为经非采供血途径感染HIV者中,42例(79.24%)为经性传播,4例(7.55%)经输血传播,7例(13.21%)传播途径不详。结论 2007年后报告的经采供血途径感染HIV者中,多数确为经既往不安全采供血(浆)途径感染。
Objective To verify the information on the pathogen infection and immunization of human immunodeficiency virus (HIV) reported in the post-2007 integrated information system on AIDS prevention and control and to find out the true route of infection. Methods Four counties in Henan Province and Anhui Province were selected to investigate the cases of HIV infection by means of blood collection and supply in the comprehensive AIDS prevention and control information system from January 1, 2007 to July 31, 2010. Pre-positive high-risk behavior exposure history, past history of HIV antibody test, diagnosis of the disease course status, the above information to re-judge the possible routes of infection. Results After the investigation, 410 valid questionnaires were retrieved. After verification, 357 subjects were infected by blood and blood supply and 53 by non-blood supply. Statistically, there was no significant difference in the composition of age, sex and course of disease among the two groups of people infected with HIV in the study subjects. Of the 53 patients newly diagnosed with HIV infection by non-blood supply, 42 (79.24%) were sexually transmitted, 4 (7.55%) were transfused, and 7 (13.21%) were unknown. Conclusion Most of the HIV-infected persons reported by the blood collection and blood supply system after 2007 reported that most of them were infected by the unsafe blood supply (plasma) route.
