目的了解陕西省商南、山阳、镇安三个县,实施全球基金项目前后(2000-2008年)艾滋病疫情变化情况。方法收集整理3个县2000-2008年逐年艾滋病病毒/艾滋病(HIV/AIDS)监测资料及专题调查资料,建立数据库并进行流行病学、统计学分析。结果2000-2008年3个县共报告HIV抗体阳性者42例,其中AIDS病人33例,累计死亡16例。78.57%(33/42)的阳性者经非法采供血感染,其中6例又感染其配偶或性伴侣,夫妻间传播率为23.08%(6/26)。9年间未发现经血液途径的新感染者,未出现母婴传播。2008年报告2例经性途径感染且与已知经采供血感染者没有关联的阳性者。结论2000年至今,陕西省全球基金项目县艾滋病疫情大幅下降,经采供血传播HIV已基本被阻断,但需警惕经性途径传播疫情的上升。
Objective To understand the changes of AIDS epidemic situation in the three counties of Shangnan, Sanyang and Zhenan in Shaanxi Province before and after the implementation of the Global Fund Project (2000-2008). Methods To collect and sort out the yearly HIV / AIDS surveillance data and special investigation data from 2000 to 2008 in 3 counties, establish a database and carry out epidemiological and statistical analysis. Results In 2000-2008, 42 HIV-positive cases were reported in 3 counties, including 33 AIDS patients and 16 cumulative deaths. 78.57% (33/42) of the positive persons were infected by illegal blood supply, of which 6 were infected with their spouse or sexual partners. The rate of transmission was 23.08% (6/26). No new infections were reported in 9 years through the bloodstream and no mother-to-child transmission occurred. In 2008, 2 positive cases were reported that were sexually transmitted and not associated with known blood-supply infections. Conclusion Since 2000, the AIDS epidemic in the global fund project counties in Shaanxi Province has dropped significantly. Transmission of HIV by blood collection and blood supply has been basically blocked. However, vigilance should be taken to guard against the rise of epidemics transmitted through sexual channels.
