摘　　要：目的了解婴幼儿急性呼吸道感染的病原学构成及临床特征,探究更快缓解临床症状的治疗方案。方法选取年龄为3个月至3岁之间因急性呼吸道感染住院治疗的婴幼儿179例,采集每例患儿鼻咽吸取物1份,运用直接免疫荧光法检测7项呼吸道病毒抗原,并分析其结果。结果在179例送检标本中,阳性检出率为35.2%,其中呼吸道合胞病毒感染占阳性标本的52.4%。病毒检测阳性患儿临床症状体征更明显(t=5.016,P<0.01)。结论病毒是婴幼儿呼吸道感染的主要病原,以呼吸道合胞病毒最常见。Objective To study the pathogenicity characters and the clinical features of infants with acute respiratory infection so as to explore therapeutic regimen for earlier relief of clinical symptoms .Methods Totally 179 cases of infants （ age ranging from 3 months to 3 years） hospitalized for acute respiratory infection were selected .Nasopharyngeal aspirates were collected once from each infant for detection of seven respiratory virus antigens by direct immunofluorescence assay .Results Of the 179 samples, the positive rate was 35.2%. Respiratory syncytial virus （RSV）-infected samples accounted for 52.4% of the positive samples.The clinical symptoms of infants with positive results of virus detection were more apparent .Conclusion Virus is the major pathogen causing respiratory infections in infants , and RSV is the most common virus .
