目的 了解浙江省金华市无偿献血者人类免疫缺陷病毒(human immunodeficiency virus,HIV)感染的状况及流行特征,以确定低危献血人群,降低输血传播HIV的风险。 方法 对2006年1月至2012年7月266 844例无偿献血者利用酶联免疫吸附试验进行抗-HIV检测,结果采用免疫蛋白印迹(WB)确证,并对抗-HIV确证阳性者进行流行病学调查与统计分析。 结果 抗-HIV抗体初筛阳性共406例,WB法确证阳性29例,阳性率为0.01%,不确定5例,其余确证为阴性。经流行病学调查,异性传播19例,占65.5%。同性传播9例,占31%。 结论 结合本地区献血人群的HIV感染状况、流行特征,应从无偿献血招募、体检咨询工作方面采取积极有效的措施,需加强与社会互动,开展对献血者艾滋病相关知识的宣教,从而达到保证血液质量与安全。
Objective To understand the infection status of human immunodeficiency virus(HIV) and related epidemiological characteristics in non-remunerated blood donors in Jinhua, Zhejiang province and determine low-risk blood donors to reduce the risk of HIV transmission through blood transfusion.
