摘要:

目的 了解中国阿米巴痢疾的发病特点、流行规律及变化趋势等,为今后因地制宜制定防控策略和监测措施、优化资源配置提供科学依据。方法 收集传染病报告信息管理系统中发病日期为2020年1月1日—2021年12月31日的阿米巴痢疾个案数据和人口学数据,采用描述流行病学分析法分析阿米巴痢疾的发病特点和变化趋势,运用ArcGIS和SaTScan软件分析2020—2021年全国阿米巴痢疾的空间分布特征和时空聚集性。结果 2020和2021年全国分别报告阿米巴痢疾病例670和539例,发病率分别为0.048/10万和0.038/10万。与2020年相比,2021年报告发病数和发病率分别减少19.55%和20.83%。2020和2021年的报告病例高峰月分别为5月(85例)和6月(73例),5—7月为两年的共同流行季节。2020和2021年的报告发病数男女性别比分别为1.27∶1和1.28∶1;报告发病数和发病率随年龄增长均呈先降后升再降趋势,0~ < 5岁年龄组的报告发病数和发病率均最高,分别为326例、0.40/10万和197例、0.25/10万。2020和2021年报告病例均以散居儿童为主,分别占报告发病数的45.82%(307/670)和33.77%(182/539);其次是农民,分别占22.09%(148/670)和26.53%(143/539)。2020年报告发病率居前3位的依次为广西(0.32/10万)、河南(0.16/10万)和广东(0.12/10万),2021年前3位依次为广西(0.22/10万)、云南(0.19/10万)和广东(0.09/10万);2020—2021年,广西和广东的报告发病率和发病数均居全国前三,同时呈下降趋势。全局空间自相关分析显示,阿米巴痢疾在省级和县级水平上均不存在空间聚集性;时空扫描分析探测出2个有统计学意义的聚集区域,均属于2021年,聚集区域的中心分别在云南和贵州,共涉及中国西南地区17个县(市、区)。结论 2020—2021年全国阿米巴痢疾报告发病数和发病率均呈下降趋势,西南部地区存在2个聚集区域。

Abstract:

Objective To investigate the incidence, epidemiological characteristics and changing trends of amoebic dysentery in China, so as to provide insights into formulation of tailored control strategies and surveillance measures and optimization of resource allocation in the futur. Methods Individual data and demographic data of cases of amoebic dysentery with dates of disease onset between January 1, 2020 and December 31, 2021 were collected from the Infectious Disease Report Information Management System, and the incidence and its changing trends of amoebic dysentery were analyzed using a descriptive epidemiological method in China from 2020 to 2021. In addition, the spatial distribution characteristics and tempo-spatial clusters of amoebic dysentery were identified using the ArcGIS and SaTScan software. Results A total of 670 and 539 cases of amoebic dysentery were reported in China in 2020 and 2021, with incidence of 0.048/100 000 and 0.038/100 000, respectively. The reported incident cases and incidence of amoebic dysentery in 2021 decreased by 19.55% and 20.83% as compared with those in 2020, respectively. The number of reported incident cases peaked in May 2020 (85 cases) and June 2021 (73 cases), and the period from May to July was the common epidemic season for both years. The ratios of male to female reported incident cases were 1.27 ∶ 1 and 1.28 ∶ 1 in 2020 and 2021, respectively. Both the reported incident cases and incidence of amoebic dysentery appeared a tendency towards a decline followed by a rise, and then a decline with ages, and the highest numbers of reported incident cases and incidence of amoebic dysentery were all found at ages of 0 to 5 years, with 326 incident cases and 0.40/100 000 incidence in 2020 and 197 incident cases and 0.25/100 000 incidence in 2021. The reported incident cases were predominantly found among diaspora children in 2020 and 2021, accounting for 45.82% (307/670) and 33.77% (182/539) of totally reported cases, followed by farmers, accounting for 22.09% (148/670) and 26.53% (143/539), respectively. The provinces (autonomous regions) with the three highest incidence were Guangxi (0.32/100 000), Henan (0.16/100 000) and Guangdong (0.12/100 000) in 2020, and Guangxi (0.22/100 000), Yunnan (0.19/100 000) and Guangdong (0.09/100 000) in 2021, respectively. Both Guangxi and Guangdong were among the top three provinces (autonomous regions) in both years in terms of both reported incidence and incident cases of amoebic dysentery, which both appeared a tendency towards a decline from 2020 to 2021. Global spatial autocorrelation analysis revealed no significant spatial clustering of amoebic dysentery at either a provincial or county level. Space-time scan analysis detected two statistically significant clusters in 2021, and the cluster areas were found in Yunnan and Guizhou, which involved 17 counties (cities, districts) in southwestern China. Conclusion The incident cases and incidence of amebiasis appeared a tendency towards a decline in China from 2020 to 2021, with two cluster areas in southwestern China.
