摘要:

目的 了解2013—2017年大理州手足口病患儿病原学特征,为手足口病防控提供依据。方法 收集2013—2017年大理州各医疗机构手足口病患儿的流行病学数据及其咽拭或粪便样本2 873份,按照年度、样本类型、患儿性别及年龄和检出地区及月份分组。采用实时荧光定量聚合酶链反应(PCR)检测临床样本中的肠道病毒71型(EV71)、柯萨奇病毒A16型(CoxA16)及其他肠道病毒(EV)。结果 2 873份临床样本中,各组EV71、CoxA16、其他EV比较差异均有统计学意义(χ2值分别为893.68、121.18、41.07、354.25、240.33,P<0.05)。3~5岁组EV71和CoxA16检出率最高,分别为25.1%和23.3%。EV71主要在春季被检出,而CoxA16、其他EV则集中在夏季被检出;男性与女性患儿之间其他EV、EV71和CoxA16检出率差异均无统计学意义(χ2=2.66,P>0.05)。结论 强化病原监测是防控手足口病的科学手段。

Abstract:

Objective To understand the etiological characteristics of children with hand,foot and mouth disease in Dali Prefecture from 2013 to 2017,and to provide a reference for its prevention and control. Methods The epidemiological data and the clinical specimens of 2 873 children with hand,foot and mouth disease from medical institutions in Dali Prefecture were collected from 2013 to 2017. All the subjects were classified according to years,specimen types,sex,regions,months and ages. Enterovirus 71(EV71),coxsackievirus A16(CoxA16) and other enteroviruses(EV)were determined by real-time fluorescence quantitation polymerase chain reaction(PCR). Results There was statistical significance for EV71,CoxA16 and other EV classifying according to years,specimen types,ages,regions and months(χ2=893.68,121.18,41.07,354.25 and 240.33,P<0.05). The determination rates of EV71 and CoxA16 in 3-5-year-old group were the highest among age groups,which were 25.1% and 23.3%,respectively. EV71 was determined mainly in spring,and CoxA16 and other EV were determined mainly in summer. There was no statistical significance for the determination rates of other EV,EV71 and CoxA16 between males and females(χ2=2.66,P>0.05). Conclusions Strengthening pathogen surveillance is a scientific means on preventing and controlling hand,foot and mouth disease.
