通过对102例住院的急性呼吸道感染患儿鼻咽分泌物中呼吸道合胞病毒和腺病毒抗原检测,结果显示:两种病毒所引起的急性呼吸道感染总阳性率为44.10％,表明近二分之一的急性呼吸道感染患儿为其所致,并可能为儿科病区通过空气传播的重要感染原。通过对探视前后儿科病房空气中的细菌学调查,结果表明:探视后空气中条件致病菌和非致病菌的含量略有增加,而探视前后的致病性金黄色葡萄球菌阳性率有显著差异(P<0.05)。说明探视后空气中的致病性金黄色葡萄球菌含量增加为探视所致。
Through the detection of 102 cases of respiratory syncytial virus and adenovirus antigen in nasopharyngeal secretions of 102 hospitalized children with acute respiratory infection, the total positive rate of acute respiratory infections caused by the two viruses was 44.10%, indicating that nearly two-thirds One of the children with acute respiratory infections is caused by it, and may be an important infectious agent of airborne in pediatric wards. The results of the bacteriological survey of the air in the pediatric wards before and after the visit showed that there was a slight increase in the number of pathogenic bacteria and non-pathogenic bacteria in the air after the visit, and the positive rates of pathogenic Staphylococcus aureus before and after the visit were significant Difference (P <0.05). Description of the air after the visit of pathogenic Staphylococcus aureus increased due to visit.
