| 摘 要： | 目的 探测2011-2018年兰州市艾滋病（aquired immunodeficiency syndrom，AIDS）流行特征及县区级人类免疫缺陷病毒（human immunodeficiency virus，HIV）感染者和AIDS病人分布的时空聚集性，为兰州市HIV/AIDS的防控提供科学参考。 方法 采用时空扫描计量法对HIV/AIDS报告数时空聚集性进行探测、检验、分析，获得艾滋病疫情在时间和空间分布上的聚集特征，并用ArcGIS 10.3实现探测结果的可视化。 结果 2011-2018年，兰州市HIV/AIDS分布共存在4个有统计学意义的时空聚集区。其中一类聚集区为城关区、安宁区和皋兰县，聚集时间为2015-2018年（LLR=108.63，RR=2.02，P < 0.001）；二类聚集区为七里河区，聚集时间为2015-2018年（LLR=60.93，RR=2.11，P < 0.001）。探测到七里河区在2014-2017年出现了异性传播的一类聚集，皋兰县、安宁区和城关区在2015-2018年出现了异性传播二类聚集；探测到皋兰县、安宁区和城关区在2015-2018年出现了同性传播一类聚集；七里河区在2017-2018年出现了同性传播二类聚集。 结论 兰州市HIV/AIDS疫情无论是病例报告数还是不同传播途径均存在时空聚集性，防控形势依然严峻，应该引起当地相关部门的高度重视。

| Abstract: | Objective To detect the characteristics of acquired immune deficiency syndrom (AIDS) epidemic in Lanzhou City from 2011 to 2018 and the spatiotemporal aggregation of human immunodeficiency virus (HIV) infection and AIDS patients at county level, and to provide scientific reference for prevention and control of HIV/AIDS in Lanzhou City. Methods The space-time scanning and measurement method was used to detect, test, and analyze the spatiotemporal aggregation of HIV/AIDS reports. The aggregation characteristics of the AIDS epidemic in time and space were obtained, and the detection results were visualized by ArcGIS 10.3. Results From 2011 to 2018, there were four statistically significant high spatial and temporal aggregation areas in HIV/AIDS in Lanzhou City. One type of gathering area was Chengguan District, Anning District and Gaolan County. The gathering time was from 2015 to 2018 (LLR=108.63, RR=2.02, P < 0.001); The second type of aggregation area was the Qilihe area, which gathered from 2015 to 2018 (LLR=60.93, RR=2.11, P < 0.001). It was detected that the Qilihe District had a type Ⅰ aggregation of heterosexual transmission from 2014 to 2017, and Gaolan County, Anning District and Chengguan District had a type Ⅱ aggregation of heterosexual transmission from 2015 to 2018; It was detected that Gaolan County, Anning District and Chengguan District had a type of gathering of same-sex transmission from 2015 to 2018; In the Qilihe District, there was a second category of same-sex communication between 2017 and 2018. Conclusion The HIV/AIDS epidemic in Lanzhou City has spatiotemporal aggregation regardless of the number of reports or different transmission routes. The prevention and control situation is still severe and should be highly valued by the relevant local departments. |
