目的分析马鞍山市2008-2011年手足口病(hand,foot and mouth disease,HFMD)报告病例流行特征。方法收集整理马鞍山市2008-2011年网络直报的手足口病资料,采用描述性流行病学方法进行分析。结果马鞍山市2008-2011年共报告手足口病7 583例,年平均发病率为151.01/10万。2010年手足口病发病率最高,为262.23/10万;2008年最低,为56.97/10万。手足口病在时间上,主要集中在4～7月份,占总病例数的64.25%;年龄上,主要集中在1～4岁年龄组,占82.76%﹔性别上,男女比为1.54∶1。病原学监测结果显示,2009年阳性标本均为肠道病毒71型(enterovirus 71,EV71);2010年阳性标本以柯萨奇病毒A组16型(coxsackievirusA16,CoxA16)为主,占60.71%;2011年阳性标本以EV71为主,占69.71%。结论手足口病发病具有明显季节性和人群分布的特点,各年流行的优势型别不同,2009年和2011年主要为EV71,2010年主要为CoxA16。
Objective To analyze the epidemiological characteristics of hand, foot and mouth disease （HFMD） in Maanshan City from 2008 to 2011. Methods The information of HFMD in Maanshan City from 2008 to 2011 reported in China information system for disease control and prevention was descriptively analyzed. Results Total of 7 583 HFMD cases were reported in Maanshan City from 2008 to 2011, average annual incidence was 151.01/100 000, the highest incidence rate was in 2010 （262.23/100 000）, and the lowest one was in 2008 （56.97/100 000）. HFMD cases were mostly reported during April to July, accounted for 64.25% in total cases. Most cases were one to four years old children and accounted for 82.76%. The male to female ratio was 1.54 ： 1. The result of etiological surveillance showed that the virus type of positive specimen was type of enterovirus 71 （EV71） in 2009. The main virus type was coxsackievirus A16 （CoxA16） in 2010, which accounted for 60.71% of the positive samples. In 2011,69.71% of the virus type of positive samples was EV71.
