摘　　要：目的了解重庆市无偿献血者H IV感染的特征,以降低输血传播H IV的风险。方法收集和整理重庆市2008、2009年无偿献血者中的H IV感染者和重庆市CDC报告的H IV感染者基本信息,分析其感染特征,包括性别、年龄和感染途径。结果重庆市2008、2009年无偿献血人群的H IV感染率分别为55.8/10万（51/91 399）和72.1/10万（72/108 205）,高于全市估算的H IV感染率25.6/10万和37.0/10万,无偿献血人群的H IV感染者以18~29岁的年轻人为主,占65.89%,其他年龄段的比例分别为30~39岁占23.26%,40~49岁占7.75%,≥50岁占3.10%。感染途径以男-男性传播方式为最,占50%,异性性传播的比例为47.06%,静脉吸毒传播占2.94%。结论应结合本地区无偿献血人群中H IV感染者的特征,有针对性地加强无偿献血者献血前的咨询和对高危人群的甄别排查,从而确保血液的安全性。Objective To reduce the risk of transfusion transmitted HIV infections and develop appropriate strategies for ensuring blood safety under current circumstances.HIV prevalence among voluntary blood donors in Chongqing between 2008 and 2009 was analyzed.Methods Information of HIV infected individuals from voluntary blood donors between 2008 to 2009 was collected and the epidemiological characteristics（gendre,age,transmission route）were analyzed and compared to those of the total HIV infected individuals reported in Chongqing.Results The HIV infection rate of voluntary blood donors was higher than estimated infection rate of the general population in Chongqing,with 55.8/100 000（51/91 399） vs 25.6/100 000 and 72.1/100 000（72/108 205） vs 37.0/100 000 in 2008 and 2009 respectively.Most infections were caused by sex contact among men who had sex with men,which accounted 50% and followed by heterosexual transmission 47.06%,IDU 2.94%.And most HIV infected individuals were youths of 18 to 29 years which accounted 65.89%,followed by 30～39 age group 23.26%,40～49 age group 7.75%,50 years age group 3.10%.Conclusions Based on current situation of HIV infection among voluntary blood donors in Chongqing,health assessments and consultations prior to donation should be strengthened,and identification of high-risk donors should be enforced.
