目的了解云南省德宏州暗娼人群艾滋病病毒(HIV)监测中指纹识别技术应用情况。方法利用指纹识别技术建立云南省德宏州暗娼人群HIV监测队列,对所收集信息进行整理分析。结果 2011—2015共监测暗娼6 893人,其中,实现指纹采集人数比例为76.9%(5 299/6 893),历年指纹采集率依次分别为66.2%(1 015/1 534)、78.5%(1 246/1 588)、75.2%(1 735/2 308)、92.9%(1 885/2 028)、92.1%(1 243/1 349);未采集指纹者HIV阳性率2.1%(36/1 683),指纹采集者HIV阳性率1.0%(69/7 124);指纹仅采集1次者HIV阳性率1.4%(55/4 007),指纹采集2次者HIV阳性率0.5%(14/3 117)。结论指纹识别技术在德宏州暗娼人群HIV监测作为身份识别手段具有一定优势,能在一定程度上规避阳性者的重复检测。
Objective To understand the application of fingerprinting in the HIV surveillance of female sex workers in Dehong Prefecture of Yunnan Province. Methods The HIV monitoring cohort of female sex workers in Dehong Prefecture of Yunnan Province was established by using fingerprinting technique. The information collected was analyzed. Results A total of 6 893 female sex workers were monitored in 2011-2015. Among them, 76.9% (5 299/6 893) of the people were fingerprinted, and the fingerprinting rates of previous years were respectively 66.2% (1 015/1 534) and 78.5% (1 246.1 588), 75.2% (1 735/2 308), 92.9% (1 885/2 028) and 92.1% (1 243/1 349) respectively. The HIV positive rate of those who did not collect fingerprints was 2.1% (36/1 683 ), HIV positive rate of fingerprinting was 1.0% (69/7 124); HIV positive rate was only 1.4% (55/4 007) when fingerprinting was only once, fingerprinting HIV rate was 0.5% twice ). Conclusions Fingerprint identification (HIV) surveillance of female sex workers in Dehong Prefecture has some advantages as a means of identification, which can avoid repeated detection of positive persons to a certain extent.
