To understand the characteristics and changes of the incidence of amoebic dysentery in China during 2015-2018, explore the causes of high incidence in some areas and provide a data base for the development of national prevention and control strategies and measures. Data were collected from the infectious disease reporting management information system from Chinese Disease Control and Prevention. To understand the seasonal, population and area distributions of amoebic dysentery, descriptive epidemiological method and software SPSS 16.0 were used to analyze the amoebic dysentery data. A total of 4 366 amoebic dysentery cases were reported without death in China during 2015-2018. The reported average annual incidence was 0.08/100 000, and the overall proportion of laboratory confirmed cases was 68.23(2 979/4 366). Amoeba dysentery mainly occurred during May to October. One seasonal peak was observed in 2015 and 2017 (July and June, respectively), and two seasonal peaks were observed in 2016 and 2018 (June and October). The patients were mainly children aged under 5 years (42.28, 1 846/4 366), and the incidence rate decreased with age in children aged under 10 years. Of these, children under 1 years of age had the highest incidence rate (1.28/100 000). The number of cumulative reported cases in Guangxi, Henan, Guangdong, Heilongjiang and Jiangxi provinces ranked top five from 2015-2018, accounting for 64.50 (2 816/4 366) of the total. The cumulative cases in Dongxing county, Guangxi, in Suixian county, Henan and in Ranghulu district, Heilongjiang, respectively accounted for more than 50.00 of the total number of cases in their provinces. The incidence rate of amoebic dysentery reported in China during 2015-2018 showed a decreasing trend, with a higher incidence in children under 5 years old and a higher number of cases in some areas. It is suggested to further investigate and analyze the diagnosis and reporting of amoeba dysentery in key areas and promote the update of the diagnostic standards for amoeba dysentery.
为了解2015 - 2018年我国阿米巴痢疾发病率的特征及变化，探究部分地区高发原因，为制定国家防控策略和措施提供数据依据。数据来源于中国疾病预防控制中心传染病报告管理信息系统。为了解阿米巴痢疾的季节、人群和地区分布情况，采用描述性流行病学方法和SPSS 16.0软件对阿米巴痢疾数据进行分析。2015 - 2018年我国共报告阿米巴痢疾病例4366例，无死亡病例。报告的年均发病率为0.08/10万，实验室确诊病例占总病例数的比例为68.23%（2979/4366）。阿米巴痢疾主要发生在5 - 10月。2015年和2017年各出现1个季节性高峰（分别为7月和6月），2016年和2018年出现2个季节性高峰（6月和10月）。患者以5岁以下儿童为主（42.28%，1846/4366），10岁以下儿童发病率随年龄增长而降低。其中，1岁以下儿童发病率最高（1.28/10万）。2015 - 2018年广西、河南、广东、黑龙江和江西五省累计报告病例数位居前五位，占总数的64.50%（2816/4366）。广西东兴市、河南遂平县和黑龙江呼兰区的累计病例数分别占所在省份病例总数的50.00%以上。2015 - 2018年我国报告的阿米巴痢疾发病率呈下降趋势，5岁以下儿童发病率较高，部分地区病例数较多。建议进一步调查分析重点地区阿米巴痢疾的诊断和报告情况，推动阿米巴痢疾诊断标准的更新。
