目的分析浙江省丽水市2010—2014年梅毒与艾滋病自愿咨询检测(VCT)人群梅毒与艾滋病病毒(HIV)感染情况,为艾滋病防治政策提供科学依据。方法收集丽水市疾病预防控制中心VCT点求询者基本信息及检测结果,采用构成比、检出率对资料进行统计学描述。结果 2010—2014年VCT点累计接受25 643人VCT门诊服务,男女比例为1:1.26,其中以20~39岁的青壮年为主,所占比例为45.63%(11 700人)。咨询者中,共发现126例艾滋病病毒(HIV)新发感染者,HIV抗体阳性检测率为0.49%。在所有HIV新发感染者中,男男性行为人群(MSM)占29.37%(37人),商业异性性行为接触者占17.46%(22人),非商业非固定异性性接触者占13.49%(17人)。3种不同性接触人群HIV抗体阳性率差异明显(χ~2=133.87,P<0.05)。HIV抗体阳性检出率前3位分别是MSM(3.68%)、配偶/固定性伴阳性者(2.89%)、注射毒品者(2.13%),但差异不明显(χ~2=0.91,P=0.63)。梅毒阳性检出率为4.23%(971/22 962),但逐年下降趋势不明显(χ~2趋势=1.42,P=0.157)。结论 VCT点是丽水市新发现HIV感染者重要窗口。

Objective To analyze the prevalence of human immunodeficiency virus （HIV） infection and syphilis among examinees of voluntary counseling and testing （VCT） for HIV in Lishui city of Zhejiang province during the period from 2010 to 2014 ,and to provide evidences for making HIV/AIDS prevention strategies. Methods General information and detection results for attendees of VCT clinics administered by Lishui Municipal Center for Disease Control and Pre- vention were collected and analyzed with descriptive statistics as constituent ratio and detection rate. Results During the 5-year period,a total of 25 643 people accepted VCT service and the male to female ratio of the attendees was 1：1.26. The majority （76. 32% ） of the attendees were aged between 20 and 39 yeas. Totally 126 HIV positive individuals were firstly detected and the overall HIV antibody positive rate was 0. 49% among the examinees. Of all the HIV positive examinees,29. 37% （37） were men who have sex with men （MSM） ;17.46% （22） reported the history of commercial heterosexual contact;and 13.49% （17） reported the history of non-commercial heterosexual contact with unfixed partners. There was a significant difference in HIV positive rate among the MSM, the attendees with commercial heterosexual contact, and the attendees with unfixed non-commercial heterosexual contact （X^2 = 133.87, P 〈 0. 05 ）. The three groups of attendees with the top three highest HIV positive rate were the MSM （3.68%） ,attendees with HIV positive spouse or fixed sexual partner （2. 89% ）, and injection drug users （2. 13% ）, without significant differences in the positive rate among the three groups （X^2 = 0.91, P = 0.63 ）. The detection rate of syphilis was 4. 23 % （971/22 962） and no obvious 2 change trend was observed in the rate （X^2trend = 1.42,P = 0. 157）. Conclusion VCT for HIV plays an important role in identifying new HIV infection patients in Lishui municipality.
