天津市无偿献血人群HIV感染状况调查

Epidemiological investigation of HIV infections among voluntary blood donors in Tianjin

目的了解天津市献血者HIV感染的流行特征,为更好地制定防控策略,保障用血安全提供依据。方法采用ELISA试剂盒法对2011年-2015年天津市血液中心698 702份无偿献血者血液样本进行HIV感染状况筛查,对初筛阳性样品采用免疫印迹法(WB法)进行感染状况确认;通过问卷调查收集确认阳性者的人口学特征等信息。结果2011年-2015年天津市血液中心无偿献血者中HIV平均感染率为0.017 3%,呈逐年升高趋势(χ~2=33.14,P<0.01)。男男性接触(MSM)是最主要的感染方式,占65.3%。HIV感染以男性为主,占90.1%;在年龄分布上以青壮年为主,其中≤30岁个体占62.8%。结论天津市无偿献血人群HIV感染率呈逐年升高趋势,应进一步加强防控措施和人群筛选策略,以确保血液安全。

MSM was the main route of HIV transmission that accounted for 65. 3%. Most HIV infected individuals were male which accounted 90. 1%,and young adults were the main group in the distribution of age,and individuals≤30years accounted for 62. 8%.
