摘要
目的了解灌南县手足口病流行的季节性分布特征。方法利用灌南县2009—2016年手足口病疫情监测资料,以发病日期转换为圆角,采用R软件,通过聚类分析法、集中度法、圆分布法等分析发病季节性。结果 2009—2016年报告手足口病3 969例,49.18%的病例发生在4-5月。8年间病例季节性分布的集中度M=0.511,角均数(95%CI)为2.07(2.04~2.10)(P<0.001),对应发病高峰日在5月1日(4月29日至5月3日)。各年度发病高峰日差异有统计学意义(P<0.05),2013年和2015年在12月或11月出现第二个发病高峰。结论该县手足口病有较强的季节性分布特征,4-5月为发病高峰期,应在高峰期前采取针对性的防控措施。
Objective To investigate the seasonal characteristics of Hand-foot-and-mouth Disease （HFMD） in Guannan county of Jiangsu Province. Methods HFMD surveillance data of Guannan county were collected from 2009 to 2016, R software was used ,the HFMD seasonal characteristics was analyzed by clustering analysis, concentration methods and circular distribution methods. Results A total of 3 969 HFMD cases were reported in Guannan county from 2009 to 2016, among whom 49.18% were reported in Apr and May. The M value of seasonal concentration was 0. 511 in last 8 years, the total angular mean （95 ~ CI） was 2. 07 （2.04--2.10） （P〈0. 001）, the corresponding peak day was on May Ist （from Apr 29th to May 3%） . The yearly peak days were significantly different （P 〈0.05）. There were secondary peaks in Dec or Nov in 2013 and 2015.
