摘要
目的了解秦皇岛市2008年与2009年手足口病流行病学特点及感染情况，为卫生行政部门制定和评价手足口病病毒感染的预防和控制策略提供依据。方法对国家疾病监测信息系统关于手足口病的资料进行统计学描述分析和推断。结果3163例手足口病患者中，以5岁以下儿童为主，占90．77％。男性多于女性，男女发病比例1．61：1。不同性别和不同年份发病的年龄构成趋势基本一致，除2009年1～8月男女组外，其余各组间差异无统计学意义。散居儿童发病率最高且2009年发病构成明显增加，2年职业构成差异具有统计学意义。2009年1～8月农村发病率呈明显上升趋势。2年发病的高峰季节都在春夏季，但2008年5月份为最高峰，2009年7月份为最高峰，高峰季节的月发病构成比较，差异具有统计学意义。2009年1—8月，实验室诊断病例以EV71阳性为主，占82．35％。3163例病例在16个月中，重复感染的11例，占0．35％。结论手足口病的发生存在明显的季节、地区、年龄差异。秦皇岛市2009年手足口病疫情较2008年呈现强度增加、范围扩大的趋势。

There was difference of disease proportions between the two peak months. 82. 35% of the patients during the period from January to August 2009 were tested EV71 positive. In 16 months, 11 patients in 3163 ones were infected repeatedly with the rate of 0. 35%. Conclusion The incidence of HFMS has significant difference between different genders, seasons and ages.
