呼吸道合胞病毒(respiratory syncytial virus,即RSV)感染是婴儿时期感染的一个常见原因。依靠临床通常是可以做出RSV感染的初步诊断,但是确诊需依赖三至七天的病毒培养。免疫荧光测定(IFA)是一个灵敏的,有特效的试验方法,它可以当天提供RSV的实验结果。在研究中,我们认为RSV的快速诊断关系到抗病毒治疗的早期实施,抗生素的使用,住院时间的长短,以及医院内RSV传 Respiratory syncytial virus (RSV) infection is a common cause of infection in infancy. Depending on the clinical setting, a preliminary diagnosis of RSV infection can usually be made, but the diagnosis depends on three to seven days of virus culture. Immunofluorescence assay (IFA) is a sensitive and specific test method that provides the results of RSV experiments on the same day. In our study, we believe that the rapid diagnosis of RSV is related to the early implementation of antiretroviral therapy, the use of antibiotics, length of hospital stay, and RSV transmission in the hospital
