目的分析近年来宣城市宣州区手足口病流行特征和发病趋势,为手足口病防控提供科学依据。方法采用描述性流行病学方法对宣州区2009-2013年手足口病监测资料进行分析。结果2009-2013年宣州区手足口病发病呈波动上升趋势(χ~2_(趋势)=33.09,P<0.001),每年出现两次流行高峰,包括发生在春季的主高峰和秋冬季的次高峰。城区发病率高于农村(χ~2=201.58,P<0.001)男性发病率高于女性(χ~2=180.03,P<0.001),发病以5岁及以下儿童为主(93.6%);病原以肠道病毒71型(enterovirus 71,EV71)为主与柯萨奇病毒A16型(COXsackie virus A16,CoxA16)和其他肠道病毒每隔1年呈交替上升和下降。结论近年来,宣州区手足口病发病呈波动上升趋势发病具有明显的季节性、地区性和人群性需重点加强社区散居儿童手足口病防控工作。
Objective To analyze the epidemiological characteristics and incidence trend of hand-foot-mouth disease in Xuanzhou District in Xuancheng in recent years, and provide a scientific basis for prevention and control of hand-foot-mouth disease. Methods Descriptive epidemiological methods were used to analyze the monitoring data of hand-foot-mouth disease in Xuanzhou District from 2009 to 2013. Results The incidence of HFMD in Xuanzhou District fluctuated upward from 2009 to 2013 (χ ~ 2_ (trend) = 33.09, P <0.001), with two peak epidemics occurring each year, including the main peak in spring and the second in autumn and winter peak. The prevalence rate in urban areas was higher than that in rural areas (χ ~ 2 = 201.58, P <0.001). The prevalence rate in urban areas was higher than that in female (χ ~ 2 = 180.03, P <0.001) It was predominantly enterovirus 71 (EV71) and coxsackie virus A16 (CoxA16) and other enteroviruses increased and decreased alternately every one year.
