【摘要】 目的 利用地理信息系统(geographic information system, GIS)分析2016―2021年安徽省百日咳空间自相关及时空聚集性，为防控提供参考依据。方法 从中国疾病预防控制信息系统收集2016―2021年安徽省百日咳报告病例，利用GIS建立数据库，进行空间自相关及时空聚集性分析。结果 2016―2021年安徽省共报告百日咳923例，年均报告发病率为0.25/10万；每年5―8月为发病高峰；空间自相关分析结果显示，安徽省2016、2018、2019及2021年百日咳发病呈显著空间聚集性。2016、2018―2021年共扫描出28个“高-高”聚集区，主要集中于六安市、芜湖市、宣城市、黄山市、滁州市、蚌埠市、合肥市、淮南市的部分县区。安徽省2016―2021年百日咳发病共扫描出13个显著性聚集区，Ⅰ类聚集区主要位于六安市、蚌埠市、滁州市、芜湖市、马鞍山市、合肥市的部分县区，聚集时间以6―9月为主，2018、2021年聚集时间从6月持续至12月。结论 2016―2021年安徽省百日咳发病以夏季聚集为主，聚集区域主要集中在省际交界县区及交通便捷的省会及大型城市周边，应加强对重点地区的监测及防控工作。更多还原

【Abstract】 Objective To analyze the temporal and spatial clustering and spatial correlation of pertussis in Anhui Province from 2016 to 2021 by using geographic information system(GIS), and to provide reference for prevention and control. Methods The reported cases of pertussis in Anhui Province from 2016 to 2021 were collected from the Chinese Disease Control and Prevention Information System, and a database was established by GIS to analyze spatial autocorrelation and spatiotemporal clustering. Results From 2016 to 2021, a total of 923 cases of pertussis were reported in Anhui Province, with an average annual reported incidence of 0.25/100 000; the peak incidence was from May to August every year; Spatial autocorrelation analysis showed that the incidence of pertussis in Anhui Province in 2016, 2018, 2019 and 2021 showed significant spatial clustering. In 2016 and 2018-2021, a total of 28 "High-High" aggregation areas were scanned; It was mainly concentrated in some counties and districts of Lu′an, Wuhu, Xuancheng, Huangshan, Chuzhou, Bengbu, Hefei and Huainan; A total of 13 significant aggregation areas were scanned for the incidence of pertussis in Anhui Province from 2016 to 2021, and the Class Ⅰ aggregation areas were mainly located in some counties and districts of Lu′an, Bengbu, Chuzhou, Wuhu, Ma′anshan, and Hefei. The gathering time was mainly from June to September, and the gathering continued until December in 2018 and 2021. Conclusions From 2016 to 2021, the incidence of pertussis in Anhui Province is mainly gathered in summer. The agglomeration area is mainly concentrated in the inter-provincial border counties and districts, and the provincial capital with convenient transportation and around large cities. The monitoring and prevention work in key areas should be strengthened.更多还原
