呼和浩特地区急性呼吸道病毒感染的病原学构成调查

Study on the viral etiology of the acute respiratory infections in Hohhot

目的:调查呼和浩特地区急性呼吸道病毒感染的病原学构成情况。方法:收集呼和浩特地区2009年-2011年急性呼吸道感染病例标本561份,采用多重PCR方法检测15种急性呼吸道感染常见病毒。结果:检测的561份样本中171份为阳性,阳性检出率为30.48%;8份为混合感染病例,占阳性样本的4.68%。阳性样本中以流感病毒和腺病毒为主,一年四季中均可检出。病毒检出率最高的是4月-6月份。呼吸道病毒的检出率在散居儿童中较高,达到48.15%。结论:近3年来,引起呼和浩特地区急性呼吸道疾病的主要病原以流感病毒为主,其次是腺病毒。

Objective：To study the viral etiology of the acute respiratory infections in Hohhot.Methods： From 2009 to 2011,561 acute respiratory infection samples were collected in Hohhot.15 kinds of common acute respiratory infection virus were detected by multiplex PCR.Results： 171 positive samples were identified from the 561 swabs,the positive rate was 30.48%;8 samples were mixed infections,which occupied 4.68% of the positive samples.Main positive samples were Influenza virus and adenovirus.The influenza virus and adenovirus could be detected in four seasons.The highest virus detection rate was found from April to June.The positive rate was 48.15% in the scattered children.Conclusion： Over the past three years,influenza virus was the main pathogen leading to acute respiratory disease in Hohhot,the next was adenovirus.
