摘　　要：目的分析北京市东城区手足口病发病时间分布特征,为防制手足口病提供依据.方法按发病日期整理传染病报告信息管理系统中,2010-2018年现住地址为东城区的手足口病月发病资料,采用集中度和圆形分布分析法对手足口病发病时间分布的集中趋势进行分析,用雷氏检验法对平均角是否存在进行检验.结果2010-2018年东城区共报告手足口病5958例,年均发病率为68.28/10万.集中度分析结果:M值为0.52,平均角=195.31°,发病高峰为7月18日,高峰期为5月28日至9月6日.各年度发病高峰出现的时间不同,高峰期的长短和起止时间不同.结论2010-2018年东城区手足口病发病具有较强的季节性,发病高峰为7月中旬.集中度和圆形分布能较好地描述手足口病季节流行特征.Objective To analyze the time distribution characteristics of hand,foot,and mouth disease(HFMD)in Dongcheng district of Beijing,so as to provide supports for the prevention and treatment of HFMD.Methods The monthly incidence data of HFMD cases with current addresses within Dongcheng district from 2010 to 2018 were sorted out from the disease surveillance information reporting management system according to the dates of onset.The concentration ratio and circular distribution index were used to analyze the trend of clustering in dates of onset of HFMD.The Rayleigh test was used to test the existence of the average angle.Results A total of 5958 cases were reported in Dongcheng district from 2010 to 2018,with an average annual incidence of 68.28/100,000.For the clustering analysis,the concentration ratio(M)was 0.52 and the average angle()was 195.31°while the incidence peak of HFMD was on July 18 and the peak period was from May 28 to September 6.Different peak dates,length as well as the start and end dates of peak period were observed in each year.Conclusions The incidence of HFMD showed obvious seasonality characteristics.The peak period of incidence was mid-July.The concentration ratio and circular distribution can describe the seasonal epidemic characteristics of HFMD.
