Repeated respiratory viral infections in children / 中华实用儿科临床杂志

ABSTRACT

Respiratory virus is a common cause of acute respiratory tract infection, especially in infant that accounts for 80%.However, reinfections usually occur after primary infection, which is not only infected by the different virus strains, but also the identical virus strains.Reinfections are common in children.As the pandemic of the 2019 novel coronavirus (2019-nCoV), its reinfections are similar to other respiratory viruses.Repeated respiratory viral infections in infants may lead to recurrent wheezing and asthma, which are also responsible for declined lung function and chronic obstructive pulmonary disease in adults.This study aims to review the epidemiology, pathogenesis and long-term effects of repeated respiratory viral infections in children, thus improving the ability to identify and support further research and vaccine strategy.
