江苏省2011—2012年新报告HIV／AIDS新发感染状况分析

Status of recent infection on new reported HIV/AIDS in Jiangsu province,2011 - 2012

目的了解江苏省新报告艾滋病病毒感染者(HIV)及艾滋病患者(AIDS)的新发感染状况,计算新发感染比例。方法对江苏省新报告的HIV/AIDS 2 145例,应用BED HIV-1 IgG捕获酶免疫(BED-CEIA)法检出其中的新发感染者,按不同的感染途径和样本来源计算各感染途径和样本来源的HIV/AIDS中新发感染的比例。结果新报告HIV/AIDS中同性传播的新发感染比例为26.97%(260/964),异性传播为16.77%(162/966),注射毒品为19.85%(27/136);新报告HIV/AIDS中来源于自愿咨询检测、专题调查及无偿献血人员检测的新发感染比例分别为30.98%(149/481)、28.57%(60/210)及36.63%(37/101),来源于术前检测、性病门诊、其他就诊者检测及其他羁押人员体检的新发感染比例分别为16.06%(44/274)、19.42%(27/139)、15.12%(75/496)及17.42%(23/132)。结论江苏省新报告HIV/AIDS中男男同性传播的新发感染比例最高,状况不容乐观;应加强主动发现的手段以尽早发现HIV/AIDS,减少二代传播。

Objective To understand human immunodeficiency virus（HIV） recent infection of new reported HIV/ AIDS in Jiangsu province, and to estimate the proportion of recent infection. Methods Samples of 2 145 newly reported HIV/AIDS cases were tested with BED HIV-1 IgG capture enzyme immunoassay（BED-CEIA） to find recent infections and to estimate the proportion of recent infection according to different HIV transmission mode and sample source. Results Among cases infected through homosexual, heterosexual and sharing syringes, recent infections were 26.97% （260/964）, 16.77% （162/966） and 19.85% （27/136） respectively. Analyzed by sample sources such as from voluntary counseling and testing, from project survey, unpaid blood donation, preoperative test, STD clinics, other hospital patients and other detainees test separately, the proportion of recent infections were 30. 98% （ 149/481 ）, 28.57% （ 60/210 ）, 36. 63% （ 37/101 ）, 16. 06% （ 44/274 ）, 19.42% （ 27/139 ）, 15.12% （ 75/ 496） and 17.42% （23/132）. Conclusion Proportion of recent infection among men who have sex with men （MSM） ranked 1 st in the new reported HIV/AIDS in Jiangsu province resulted in unoptimistic current situation. The initiative to detect HIV/AIDS cases should be strengthened to reduce secondary transmission.
