摘要
目的掌握2013年至2015年内蒙古手足口病（Hand,foot and mouth disease,HFMD）病原学检测结果,为HFMD防制提供科学依据。方法对描述其三间分布特征及临床类别与样本类型,数据分析采用卡方检验。结果 2013年至2015年HFMD实验室检测阳性率分别为59.2%、64.7%、48.9%。检测阳性率最高的为中部区,68.3%,最低为东部区,45.1%。3年间EV71型和CVA16型HFMD占比均逐年下降,其他型别呈逐年上升趋势,且2015年占比高达53.7%。6~7月为发病高峰,9月会再次出现小高峰。发病人群以5岁以下儿童为主,男性：女性为1.3：1,差异无统计学意义（χ2=0.4,P〉0.05）。临床类型以轻症为主,咽试子较肛拭子与疱疹液更敏感。结论 2013年至2015年内蒙地区HFMD发病呈逐年下降趋势,中部区为高发,其他型别已成优势流行株,6~7月为高发期,5岁以下儿童易感,咽试子较敏感。
Objective To master the pathogenic detection results of hand foot mouth disease （HFMD） in Inner Mongolia from 2 0 1 3 to 2 0 1 5 ,and to provide scientific basis for the prevention and control of HFMD . Methods By means of describing the distribution characteristics and clinical classification and sample types , some of the rate or composition ratio of the chi - square test was used to verify whether the difference was statis -tically significant .Results The positive rates of HFMD were 5 9 .2 % ,6 4 .7 % and 4 8 .9 % ,respectively ,from 2 0 1 3 to 2 0 1 5 .Detection of the highest positive rate for the central region ,6 8 .3 % ,the lowest for the eastern region ,4 5 .1 % .Three years of EV7 1 type and HFMD type CVA1 6 accounted for both decreased year by year , and other types increased year by year ,and in 2 0 1 5 accounted for as high as 5 3 .7 % .6 ~ 7 for the peak ,in 9 will be a small peak again .The incidence in children under 5 years old ,male and female is 1 .3 ：1 ,the difference was not statistically significant （χ2 = 0 .4 , P〉 0 .5 ） .Clinical types were mainly mild to severe disease ,and the sensitivity of the throat swab was more sensitive than that of the anal swab .Conclusions The incidence of HFMD in Inner Mongolia area was decreased year by year from 2 0 1 3 to 2 0 1 5 ,the middle area was high ,the other types had become the dominant epidemic strains ,and 6 to 7 was the high incidence period ,the children under the age of 5 were susceptible ,and the pharyngeal test was more sensitive .
