摘要
[目的]对2009-2014年玉溪市手足口病例流行病学和病原学分析,为手足病防控提供科学依据。[方法]对2009-2014年《中国疾病预防控制疾病监测信息报告管理系统》等手足口病监测数据进行描述性流行病学研究。[结果]2009-2014年玉溪市手足口病流行呈现周期性趋势,高发区域呈片状分布,各县/区中心城区高发,郊区及城区结合部报告病例较少。患者全年发病,高峰主要集中在4-7月份和11月至次年1月,呈双峰型分布;发病年龄以5岁及以下儿童为主;发生了5次优势病原体的更替,在普通病例中EV71型和Cox Al6型手足口病所占比例分别为43.01%和41.71%,但EV71型手足口病在死亡病例及重症病例中所占比例分别为100%和85.13%,而其他肠道病毒和Cox Al6型分别占重症病例的7.81%和7.06%。[结论]玉溪市手足口病控制需要根据其流行规律和病原谱的变化情况,提出有针对性的控制措施,并对EV71型进行更加深入的亚型和流行病学研究,为制定预防控制策略提供依据。
Objective To analyze the epidemiological and Etiological characteristics of hand-foot-mouth disease（ HFMD） in Yuxi from 2009 to 2014,and to provide scientific basis for the prevention and control of HFMD. Methods Descriptively and epidemiologicaliy studied HFMD surveillance data to＂Chinese Disease Prevention and Control Surveillance I1 nformation System Report＂from 2009 to 2014. Results From 2009 to 2014,it indicated a cyclical incidence trend of HFMD in Yuxi. The high HFMD incidence area distributed as flakiness. High morbidity was in the central cities or counties,and less was in suburbs urban area. Morbidity was throughout the year. Peak time concentrated from April to July,and November to next January. Most cases were under 5 years old. Enterovirus 71（ EV71） and Coxsackie virus A16（ Cox Al6） were43. 01% and 4171% respectively in common cases. EV71 was（ 100% and 85. 13%） respectively in death and severe cases. Other EV71 and Cox Al6 were 781% and 7. 06% in severe cases. Conclusions HFMD control need according to the popular rule and the changes of pathogens spectrum,and the targeted control measures are put forward. The subtypes of EV71 type should be more in-depth and epidemiological studies to provide evidence for prevention and control strategy.
