摘　　要：目的探讨798例呼吸道感染患儿呼吸道病毒的检出情况及其流行特征。方法选取2018年12月~2019年12月就诊于江门市妇幼保健院的798例呼吸道感染患儿作为研究对象,采集呼吸道分泌物,检测呼吸道病毒。分析呼吸道感染患儿呼吸道病毒检出情况、各种呼吸道病毒构成及其与年龄、季节关系。结果798例呼吸道感染患儿中共检出阳性标本279份(34.96%),其中混合感染6份(0.75%),均为2种病毒感染;279份阳性标本中以呼吸道合胞病毒(RSV)最为常见,检出率为18.55%,其次为流感病毒A型(IFA),检出率为7.39%;随着年龄增长腺病毒(ADV)、RSV、副流感病毒(PIV)Ⅰ型、PIVⅡ、PIVⅢ阳性率呈现下降趋势,流感病毒B型(IFB)、IFA呈现升高趋势,<1岁呼吸道病毒检出率为45.33%,高于1~<3岁、3~<6岁、≥6岁病毒感染阳性率,差异有统计学意义(P<0.05);春季、冬季是呼吸道病毒感染的高发季节,呼吸道病毒阳性率分别为47.19%、34.50%,高于夏季、秋季,差异有统计学意义(P<0.05)。结论呼吸道病毒感染患儿呼吸道病毒检出率较高,主要致病病原体为RSV、IFA,春季、冬季为高发季节,多发于1岁以下婴幼儿。Objective To explore the prevalence of respiratory viruses in 798 children with respiratory tract infection.Methods A total of 798 children with respiratory tract infection from December 2018 to December 2019 in Jiangmen Maternal and Child Health Hospital were selected as the research objects.Respiratory secretions were collected and respiratory viruses were detected.Objective to analyze the detection of respiratory viruses in children with respiratory tract infection,the composition of various respiratory viruses and their relationship with age and season.Results 279(34.96%)positive samples were detected in 798 children with respiratory tract infection,among which 6 cases(0.75%)were mixed infection,both of which were two kinds of virus infection;respiratory syncytial virus(RSV)was the most common in 279 positive samples,with the detection rate of 18.55%,followed by influenza virus A(IFA),the detection rate was 7.39%;with the growth of age,the positive rates of adenovirus(ADV),RSV,and parainfluenza virus(PIV)typeⅠ,PⅣⅡ,and PIVⅢshowed a downward trend,while influenza virus type B(IFB)and IFA showed an upward trend.The positive rate of respiratory virus infection was 45.33%in<1-year-old group,which was higher than that 1-<3-year-old group.3-<6-year-old group and≥6-year-old group(P<0.05).The sex rates were 47.19%and 34.50%respectively,which were higher than those in summer and autumn(P<0.05).Conclusion The detection rate of respiratory viruses in children with respiratory tract virus infection is high.The main pathogenic pathogens are RSV and IFA.The high incidence seasons are spring and winter,and most of them occur in inIFAnts under 1 year old.
