摘要:
目的:了解江苏省男男性行为人群(men who have sex with men,MSM)HIV的感染状况,估算HIV在该人群中的新发感染率-方法:对2008~2009年南京-扬州-苏州3城市MSM 3轮调查的3 152份样本,进行HIV-1初筛-复检及确证试验,检出的HIV-1阳性样本,再应用BED HIV-1 IgG捕获酶免疫法(BED-CEIA)检出其中的新发感染样本,进而估算该人群的HIV-1新发感染率-结果:3 152份样本共检出HIV-1阳性样本175份,其中92份被判定为新发感染,南京市3轮调查的HIV-1新发感染率分别为7.05%-5.18%-3.71%,扬州市分别为6.99%-2.39%-12.27%,苏州市分别为6.73%-3.31%-9.84%-结论:HIV-1在江苏省MSM人群中的流行仍处于较高水平,且新发感染状况不容乐观,必须加大防控力度-
Abstract:
Objective: To understand HIV infection of men who have sex with men(MSM) in Jangsu province,and to estimate the annual HIV incidence of MSM. Methods:Total 3 152 samples from 3 rounds survey in 3 cities(Nanjing,Yangzhou and Suzhou)among MSM during 2008-2009 were tested to find HIV-1 seropositive samples. HIV-1 seropositive samples were tested with BED HIV-1 IgG capture enzyme immunoassay(BED-CEIA) to find recent HIV-1 infections and to estimate the annual HIV-1 incidence of MSM. Results: There were 175 samples found to be HIV-1 seropositive,and 92 samples confirmed to be recently infected.The annual HIV-1 incidence of 3 rounds survey were 7.05%,5.18% and 3.71% in Nanjing,6.99%,2.39% and 12.27% in Yangzhou,6.73%,3.31% and 9.84% in Suzhou. Conclusion: The prevalence of HIV-1 in MSM in Jiangsu province was still at a high level. Powerful prevention and control effort must be made.
