沈阳地区婴幼儿RSV感染的病原学调查研究

RSV INFECTION AMONG INFANTS/YOUNG CHILDREN IN SHENYANG AREA

查明冬春季沈阳地区婴幼儿RSV感染流行情况。采用APAAP法和IFA法对 6 5例临床诊断为急性病毒性下呼吸道感染的婴幼儿进行了检查。在RSV感染的高发季节由RSV引起婴幼儿的急性下呼吸道感染的阳性率为 44 .6 0 % (2 9/ 6 5 ) ,0～ 6个月婴幼儿感染率最高 ,为 74.0 7% (2 0 / 2 7) ,并有明显的喘息倾向。以上结果表明RSV仍是引起婴幼儿急性下呼吸道感染 ,特别是肺炎和毛细支气管炎的重要病原体 ,沈阳地区仍有流行。为防止和控制RSV的流行及为RSV的防治提供了依据。

To investigate the prevalence of respiratory syncytial virus (RSV) infection among infants/young children in Shenyang area during falls and winters, 65 pharyngeal swabs were collected from infants/young children with acute lower respiratory infection (ALRI) and detected their RSV infection adopting APAAP and IFA methods/technique. The results showed that the positive rate of RSV infection was 44.60% (29/65) with its peaks in infants/young children with ALRI and 74.07% (20/27). All of them were under 6 months old. It suggested that RSV infection is still a predominant factor for ALRI among infants/young children, especially among those who suffer from bronchiolitis and pneumonia.
