2008—2010年天津市和平区手足口病流行特征分析

Epidemiologic Characteristics of Hand-foot-mouth Disease in Heping District of Tianjin City during 2008-2010

目的了解天津市和平区2008—2010年手足口病流行特征。方法采用描述性流行病学方法对和平区2008—2010年手足口病疫情、个案调查及病原学资料进行分析。结果 和平区2008—2010年手足口病发病率逐年上升,夏季为发病高峰,发病人群主要为托幼、散居儿童。辖区所有病例均为轻症,预后良好。和平区2010年采集手足口病病例粪便标本43份,病毒阳性率为55.81%,其中CoxA16阳性占66.67%。结论天津市和平区手足口病的发生有明显性别、年龄、季节差异。为进一步掌握该辖区手足口病流行特征,应加强对托幼机构手足口病监测并继续开展病原学监测工作。

[Objective]To understand the characteristics of Hand-foot-mouth Disease（HFMD） in Heping District of Tianjin City during 2008-2010. [Methods]A descriptive epidemiologic approach was employed to analyze the HFMD epidemic,case investigation and etiological data from 2008 to 2010. [Results]The incidence rate of HFMD in Heping District increased annually during 2008 to 2010.The incidence peak was observed in summer.Kindergarten and scattered children were mostly affected.All cases symptom was lighter with favorable prognosis.In 2010,of 43 stool specimens,the positive rate of virus was 55.81%,Coxsackie virus A 16（CoxA16） accounted for 66.67%. [Conclusion]The incidence of HFMD varies obviously with sex,age and seasons.To further master the epidemiologic characters of HFMD,monitoring of the child-care institutions and pathogenic surveillance should be strengthened.
