摘　　要：目的了解长沙地区Saffold病毒（以下简称为SAFV）在儿童呼吸道感染中的流行情况，探讨其与儿童呼吸道感染的相关性。方法选取湖南省人民医院儿科医学中心2007年11月至2008年10月间643名因呼吸道感染住院儿童的鼻咽抽吸物。采用实时荧光定量聚合酶链式反应（Realtime．PCR）方法扩增SAFV的5UTR的基因片段，并且统计分析临床资料。结果643份样本中共检测出SAFV阳性67份，阳性检出率为10．42％（67／643），5岁以上未检测出该病毒。31例患迁延性肺炎和慢性肺炎的患儿标本检出SAFV8例（25．81％），差异有统计学意义。结论本研究表明长沙地区下呼吸道感染住院儿童存在SAFV感染；SAFV可能与下呼吸道感染及病程迁延相关。Objective To investigate prevalence of Saffold virus （SAFV） in Changsha area of hospitalized children with respiratory tract infection, and to discuss whether this virus is related to respiratory tract infection of children. Methods 643 nasopharyngeal aspirates samples were collected from hospitalized children with respiratory tract infection of the first affiliated hospital of Hunan nomal university during Nov. 2007 to Oct. 2008. Real-time fluorescent quanti-tative PCR（FQ-PCR） performed to screen the 5＇UTR gene. And then analyze clinical data. Results SAFV were detected in 67 patients （ 10.42% ） out of the 643 children, it was not detected over 5 years of age. The virus were detected in 8 patients （25.81%） out of the 31 children with persistent pneumonia and chronic pneumonia, there was statistically significant. Conclusion There existed SAFV infection in hospitalized children with lower respiratory infection in Changsha area;SAFV maybe related to disease onset with lower respiratory tract infection of children.
