自从应用组织培养方法于病毒方面的研究以来,打开了发展病毒学的道路。近年在呼吸道病毒的研究方面,又有了新的进展。病毒感染对于小儿急性呼吸道疾病(以下简称ARD)的重要性,逐渐有了明确的认识。根据多数的报导来看,病毒感染约占小儿ARD的20～50％,其中现已发现的病毒约占60～70％,尚有一些病毒有待今后继续研究和鉴定。 Since the application of tissue culture methods in the study of viruses, the road to development of virology has been opened up. In recent years, research on respiratory viruses has made new progress. The importance of virus infection in pediatric acute respiratory diseases (hereinafter referred to as ARD) has gradually gained a clear understanding. According to the majority of reports, the virus infection accounts for about 20-50% of pediatric ARDs, of which about 60-70% of the viruses have been found. There are still some viruses to be studied and identified in the future.
