To understand the status of recent infected and newly reported HIV cases in Jiangsu province.
Information including general demographic, mode of transmission and sample source of newly reported HIV infected cases was collected. Corresponding serum or plasma samples were collected and tested with BED-CEIA. Proportions of recent HIV infections among different populations were calculated, and associated factors of recent HIV infection calculated.
Among cases infected through different channels as homosexual, heterosexual and needles sharing, the proportions of recent infections were 29.19% , 17.40% and 21.75% , respectively. Statistically significant difference was seen between different populations(P < 0.05). Compared with female cases, male cases were more likely to be recent infected (OR = 1.569, 95%CI: 1.168-2.107). Compared with cases older than 35 years of age, the ones that younger than that age were more likely to be recently infected (OR = 1.556, 95% CI:1.289-1.879). Compared with cases who remained single, those married cases were more likely to be long-term infections(OR = 0.789, 95%CI:0.649-0.960). Compared with patients identified by hospitals, the recent HIV infections were more likely to be found through voluntary counseling programs and testing (OR = 2.278, 95%CI: 1.853-2.801), project-based surveillance programs (OR = 2.409, 95%CI:1.860- 3.120), and unpaid blood donation sites (OR = 2.911, 95%CI:2.118-4.001)(P < 0.05).
Proportion of MSM ranked 1st in the newly reported HIV cases in Jiangsu province. Related HIV case-finding programs should be strengthened to reduce the secondary transmission.
了解江苏省近期感染及新报告艾滋病病毒（HIV）病例的情况。
收集新报告HIV感染病例的一般人口学信息、传播途径及样本来源等资料。采集相应血清或血浆样本，采用BED-CEIA法进行检测。计算不同人群中近期HIV感染的比例，并分析近期HIV感染的相关因素。
在通过男男性行为、异性性行为和共用针具等不同途径感染的病例中，近期感染比例分别为29.19%、17.40%和21.75%。不同人群间差异有统计学意义（P<0.05）。与女性病例相比，男性病例近期感染的可能性更大（OR=1.569，95%CI：1.168-2.107）。与35岁以上病例相比，35岁及以下病例近期感染的可能性更大（OR=1.556，95%CI：1.289-1.879）。与未婚病例相比，已婚病例更易为长期感染（OR=0.789，95%CI：0.649-0.960）。与医院确诊病例相比，近期HIV感染更易通过自愿咨询检测（OR=2.278，95%CI：1.853-2.801）、项目监测（OR=2.409，95%CI：1.860-3.120）和无偿献血点发现（OR=2.911，95%CI：2.118-4.001）（P<0.05）。
江苏省新报告HIV病例中男男性行为人群占比居首。应加强相关HIV病例发现项目以减少二代传播。
