2009年至2014年元江县手足口病流行病学分析

Epidemiological Analysis on Hand-foot-mouth Disease in Yuanjiang County from 2009 to 2014

目的:了解元江县2009年至2014年手足口病流行特征,为制定预防和控制策略提供依据。方法:采用SPSS 17.0统计软件对2009年至2014年元江县网络报告的手足口病监测数据进行流行病学及病原学分析。结果:2009年至2014年元江县共报告手足口病例4 060例,年均发病率为330.0/10万,发病周期呈"M"型特征。发病高峰时间段有由秋季向冬季和春季移动的趋势,而且自2011年夏季出现峰值后,发病高峰呈"双峰"型特征。病例主要集中在澧江镇、甘庄街道和曼来镇,澧江镇每年发病数均居全县第1位,而且高、中、低海拔地区发病率之间比较,差异具有统计学意义(χ2=1 581.20,P<0.01),且低海拔发病率最高(533.8/10万),高海拔发病率最低(89.6/10万)。结论:元江县手足口病的防控应结合横向和纵向手足口病发病的特征综合防控,特别是加强重点地区和重点人群的预警防控工作。

Objective:To understand the prevalent characteristics of hand-foot-mouth disease in Yuanjiang County from2009to2014,and to provide scientific basis for the disease control and prevention.Methods:SPSS17.0statistical software was used to analyze the epidemiology and etiology of hand-foot-mouth disease data based on the online report of Yuanjiang County from2009to2014.Results:A total of4060cases of hand-foot-mouth were reported in Yuanjiang County from2009to2014,the average incidence was330.0/105,and the epidemic curve showed a trend of"M"type.Morbidity peak period has the tendency of shifting from the autumn to winter and spring,appearing"twin peaks"type distribution.The hand-foot-mouth disease cases were mainly concentrated in Lijiang Town,Ganzhuang Streets and Manlai Town.Lijiang Town was the top at the number occurred of hand-footmouth disease each year.The incidence has difference among high,medium and low altitude areas(χ2=1581.20,P<0.01).The highest incidence rates were in low altitude(533.8/105),and high altitude area had the lowest incidence rates(89.6/105).Conclusion:The horizontal and vertical characteristics of hand-foot-mouth disease should be combined in prevention and control of the disease.Especially the key areas and key crowd should be strengthened on early warning,prevention and control.
