摘要
目的了解泰安地区2003年手足口病爆发的流行特征、影响因素和病原。方法收集个案调查资料、医院住院病历、疫情报告资料,对其三间分布进行分析,采集检测病人的血、粪、脑脊液等生物材料进行病毒分离、RT-PCR和血清学检测。结果全市发病2586例,发病率为47.22/10万,其中新泰市1689例,发病率为125.03/10万,平均发病年龄为2.60岁,潜伏期最短2d,最长15d,中位数为5d。高发季节为8月上旬,主要病原体为ECHO19、和ECHO30等。结论2003年7～9月,泰安地区出现了手足口病暴发流行,主要原因是病原体发生变化,由以往COX16和EV71为主转变为以ECHO19和ECHO30为主,当地低龄人群免疫力低下,而当时的湿热气候也是重要影响因素。
