In 1987, the Respiratory Group of the Pediatrics Branch of the Chinese Medical Association established the Diagnostic Reference Standards for Recurrent Respiratory Infections, and its understanding has been further improved over the past 20 years. In September 2007, the Editorial Board of the Chinese Journal of Pediatrics and the Respiratory Group of the Chinese Medical Association jointly held a Symposium on Chronic Cough and Recurrent Respiratory Tract Infections in Children in Yangzhou, Jiangsu Province.

[Definition]
Recurrent respiratory tract infection refers to the frequent occurrence of upper and lower respiratory tract infections within 1 year, which is beyond the normal range.
[Judgment conditions]
Recurrent respiratory tract infections are classified into recurrent upper respiratory tract infections and recurrent lower respiratory tract infections according to age, underlying cause and site, the latter can be further classified into recurrent tracheobronchitis and recurrent pneumonia. The specificity of infection sites is conducive to analyzing the etiology and taking corresponding therapeutic measures, while the emphasis on recurrent upper and lower respiratory tract infections, especially recurrent tracheobronchitis and recurrent pneumonia is to distinguish infectious inflammation from allergic inflammation.
