北京市大兴区2010年手足口病病原分型及采样阳性率的影响因素

Etiologic Classification of HFMD and Analysis on Influencing Factor of Positive Rate of Collecting Specimens in Daxing District of Beijing City in 2010

目的了解北京市大兴区手足口病病原种类,分析影响采样阳性率的因素,探讨提高阳性率的方法。方法利用SPSS及Excel软件,对经国家疾病监测信息报告管理系统报告的数据以及对病例标本采样检测情况进行统计,采用描述性统计方法和χ2检验。结果大兴区的手足口病病原以EV71型为主(62.12%)。影响检测阳性率的因素有发病至采样时间和标本种类;而与重症与非重症、采样至送检时间、不同标本采集单位、诊断医院级别和是否高峰期发病无关。结论为提高标本检测阳性率,应尽量选择采集疱疹液、或多部位联合采样;且应在发病后尽早采样,可行的解决方法为由首次就诊医院直接采样。

[Objective] To understand the etiologic variety of Hand,Foot and Mouth Disease（HFMD） in Daxing District of Beijing City,to analyze the influencing factor of positive rate of collecting specimens,and discuss the method as to improve it. [Methods]SPSS and Excel software were used to describe the data from the National Disease Surveillance Information Report Management System,with descriptive statistical methods and χ2 test. [Results]The major virus was Human EV71（62.12%）.The influencing factors of positive rate were the time from outbreak to specimens collecting and specimens type;not related to severity of the case,duration from collecting to sending the specimen to laboratory,the units who collecting specimens,the rankings of hospitals for diagnosis and peak infection. [Conclusion]It is necessary to choose herpes or collect specimens in different parts of body,in order to improve the positive rate of specimens.And specimens should be collected after outbreak as quickly as possible,the solution is collecting specimen in hospital which patient goes first.
