喘息为各种病毒性呼吸道感染引起的下呼吸道症状,是婴幼儿期呼吸道疾病常见临床症状。喘息性疾病占儿童急慢性疾病发病率的5%~10%[1]。1发病原因呼吸道病毒感染是儿童急性喘息性疾病发生过程中的重要危险因子,近年来PCR技术(聚合酶链式反应)证实,病毒感染可引起儿童喘息性疾病的反复发作,与婴幼儿喘息性疾病具有普遍相关性。在儿童阶段,导致喘息的主要病毒种类包括呼吸道合胞病毒(respiratory syncytial virus,RSV)、人鼻病毒(human rhinovirus,HRV)、人类偏肺病毒(human metapneumovirus,HMPV)和流感病毒(influenza viruses)等,研究表明不同的病毒种类对于哮喘病程发展的影响是不同
Breathing for a variety of viral respiratory tract infections caused by lower respiratory tract symptoms, respiratory disease is common in infants and young children clinical symptoms. Asthmatic diseases account for 5% to 10% of children’s acute and chronic diseases [1]. 1 causes of respiratory virus infection in children with acute asthmatic disease is an important risk factor in the process of PCR technology (polymerase chain reaction) confirmed in recent years, the virus infection can cause recurrent wheezing in children with wheezing and infant wheezing Diseases have universal relevance. The main viral species that cause wheezing in childhood include respiratory syncytial virus (RSV), human rhinovirus (HRV), human metapneumovirus (HMPV), and influenza viruses Etc., studies have shown that different types of viruses have different effects on the development of asthma
