武进地区冬季儿童急性下呼吸道感染病毒病原学分析

Winter in Wujin Region in Children with Acute Lower Respiratory Tract Infection of Viral Etiology Analysis

目的:了解武进地区冬季儿童急性下呼吸道感染病毒病原学特点。方法:采用直接免疫荧光法(DIF)对2013年1-3月住院的116例下呼吸道感染患儿鼻咽分泌物进行七项呼吸道病毒检测。结果:116例患儿中,39例检出至少1种病毒,总检出率33.6%。其中呼吸道合胞病毒(RSV)35例(30.2%),腺病毒(ADV)8例(6.9%),副流感3(PIV3)3例(2.6%)。流感病毒A(IFA)、流感病毒B(IFB)、副流感1(PIV1)、副流感2(PIV2)均未检出。RSV、ADV混合感染7例,检出率6.0%。结论:病毒是儿童下呼吸道感染的主要病原,武进地区冬季急性下呼吸道感染的主要病毒病原是RSV、ADV、PIV。

Objective： To understand the winter in Wujin region in children with acute lower respiratory tract infection of viral etiology.Methods： With direct immunofluoreseence assay（D/F） from January 2013 to March 2013 116 patients with lower respiratory tract infection in nasopharyngeal secretion in seven respiratory virus detection.Results： In 116 cases, 39 cases were detected at least one kind of virus, the total positive rate was 33.6%.Among them, respiratory syncytial virus （RSV） detected the most, for 35 cases, the detection rate was 30.2%, adenovirus（ADV） in 8 cases（6.9%）, parainfluenza 3（PIV3） in 3 cases（2.6%）. Influenza virus A（IFA）, influenza virus B（IFB）, parainfluenza I（PIV1）, parainfluenza 2（PIV2） was not detected.RSV, ADV mixed infection in 7 cases, the detection rate was 6.0%.Conchlsion： The virus is a major pathogen of lower respiratory tract infection in children.Acute lower respiratory tract infection in winter is the main pathogenic virus in Wujin area are RSV, ADV, PIV.
