对161例住院的呼吸道感染患儿同时检测CVB－Ag和CVB－IgM，结果发现阳性者94例，其中CVB－Ag阳性率30.43％（49/161），CVB-IgM阳性率45．96％（74/161），29例两者均阳性。3组平均发病天数分别为4．2±2.5、15.7±8．2和8.1±3．2，前组分别与后2组相比有显著差异（P＜0.01和P＜0．05）。结果表明，CVB是儿童呼吸道感染的常见病原体；将CVB－Ag和CVB－IgM联合检测，可提高CVB感染的检出率。
CVB-Ag and CVB-IgM were detected in 161 hospitalized children with respiratory tract infection. The positive rate of CVB-Ag was 30.43% (49/161) and the positive rate of CVB-IgM was 45.96% 74/161), 29 were positive for both. The average days of onset in the three groups were 4.2 ± 2.5, 15.7 ± 8.2 and 8.1 ± 3.2, respectively. There were significant differences (P <0.01 and P <0.05) between the former group and the latter two groups respectively. The results showed that CVB is a common pathogen of respiratory tract infection in children. Combined detection of CVB-Ag and CVB-IgM can improve the detection rate of CVB infection.
