INTRODUCTION
Prevalence of influenza A virus (Flu-A), respiratory syncytial virus (RSV), and human metapneumovirus (hMPV) was assessed in children with acute respiratory infections (ARIs).
METHODS
Nasopharyngeal aspirates and throat swabs were subjected to real-time polymerase chain reaction (PCR) to detect RSV and Flu-A and to conventional PCR to detect hMPV.
RESULTS
Of the 156 children assessed, 93 (59.6%) carried at least one virus, with 35.9% positive for RSV, 14.1% for hMPV, and 9.6% for Flu-A. The prevalence of co-infections was 2.6%.
CONCLUSIONS
The high detection rate may reflect increased sensitivity of real-time PCR compared to traditional PCR and viral culture.
引言
对患有急性呼吸道感染（ARI）的儿童进行了甲型流感病毒（Flu-A）、呼吸道合胞病毒（RSV）和人偏肺病毒（hMPV）的流行率评估。
方法
对鼻咽抽吸物和咽拭子进行实时聚合酶链反应（PCR）以检测RSV和Flu-A，并用常规PCR检测hMPV。
结果
在评估的156名儿童中，93名（59.6%）携带至少一种病毒，其中RSV阳性率为35.9%，hMPV为14.1%，Flu-A为9.6%。合并感染的流行率为2.6%。
结论
高检出率可能反映了与传统PCR和病毒培养相比，实时PCR的灵敏度有所提高。
