摘　　要：目的了解内蒙古地区手足口病流行特征和病原种类,为制定防控策略提供科学依据。方法采用描述性流行病学方法描述2008—2013年内蒙古手足口病流行特征,采用分析性统计学方法分析病原检测结果。结果2008—2013年全区共报告手足口病病例115 316例,各年发病率依次为32.15/10万、133.64/10万、78.16/10万、93.94/10万、66.62/10万和66.40/10万,2008—2013年手足口病报告发病数居丙类传染病首位,发病高峰为6—7月,≤3岁组病例占发病总数的58.48%;2 775例实验室诊断病例中,EV71阳性占42.92%,CA16阳性占32.11%,其他肠道病毒占24.97%;不同年份EV71、CA16、其他肠道病毒阳性构成差异有统计学意义(χ2=401.76,P<0.05),重症死亡病例感染EV71比例为82.58%。结论 2008—2013年内蒙古地区手足口病报告发病率逐年下降,发病有明显的季节性,散居儿童是主要发病人群;主要病原是EV71和CA16,EV71为优势流行株。Objective To find out epidemiological characteristics and pathogen type of hand-foot-mouth disease （HFMD） in Inner Mongolia and to provide scientific evidences for making prevention and control strategies. Methods Descriptive epidemiological methods were used to describe the epidemic characteristics of HFMD in Inner Mongolia from 2008 to 2013 and analytical statistical methods were used to analyze pathogenic detection results of HFMD. Results To- tally 115 316 HFMD cases were reported in Inner Mongolia, with the annual morbidity of 32. 15,133.64,78.16,93.94, 66.62, and 66. 40 per 100 000 people, respectively, during the six-year period. The yearly incidence peak was observed from June to July and 58.48 % of the cases were younger children aged ≤ 3 years. Among 2 775 cases with laboratory diagnosis,the positive rates of enterovirus 71 （ EV71 ） ,coxsackievirus 16（CA16） and other enteroviruses were 42. 92%, 32. 11%, and 24. 97%, respectively. There were significantly statistical differences in the positive rates of EV71, CA16 and other enteroviruses in different years （χ2 = 401.76,P 〈 0. 05）. Conclusion The morbidity of HFMD in Inner Mon- golia declined year by year from 2008 to 2013. There was an obvious seasonality in HFMD prevalence and the majority of the incidents were scattered-living younger children. The main pathogens of HFMD epidemic were EV71 and CA16, and EV71 was the dominant prevalent strain.
