目的了解昆山市2008~2012年手足口病的流行病学和病原学特征,掌握疫情变化趋势,为手足口病防治工作提供科学依据。方法采用描述性流行病学方法对手足口病病例进行流行病学特征和病原学检测结果分析。结果昆山市2008~2012年共报告手足口病病例5 517例,年均发病率为59.68/10万,无死亡病例。报告发病率从2008年的21.71/10万增至2012年的59.43/10万;男女性别比为1.56∶1,男性病例多于女性;城区发病率为45.83/10万,乡镇发病率为64.59/10万,乡镇高于城区(P<0.01);在实验室诊断病例中,EV71、CoxA16和其他肠道病毒分别占阳性病例的56.78%、30.04%和13.19%。结论 2008~2012年昆山市手足口病疫情持续流行,EV71、Cox A16和其他肠道病毒同时存在,但以EV71与Cox A16共同主导流行。
Objective To understand the epidemiological and etiological characteristics of HFMD in Kunshan from 2008 to 2012 and to grasp the trend of epidemic situation so as to provide a scientific basis for the prevention and treatment of HFMD. Methods The descriptive epidemiological method was used to analyze the epidemiological characteristics and pathogenic test results of HFMD cases. Results A total of 5 517 HFMD cases were reported in Kunshan from 2008 to 2012, with an average annual incidence of 59.68 / 100 000 without any deaths.

Among the laboratory diagnostic cases, EV71, CoxA16 and other enterovirus accounted for 56.78%, 30.04% and 13.19% of the positive cases respectively.
