Abstract: Viral pneumonia is an acute inflammation caused by a viral infection in lung parenchyma and(or) interstitial lung.Especially, in the 21st century,the viral pneumonia induced by new respiratory viruses, such as severe acute respiratory syndrome(SARS) coronavirus and new coronavirus(nCoV) has become a global public health problem facing humans.Most pathogens have no specific treatment.Traditional Chinese medicine has certain advantages and characteristics in preventing and treating childhood viral pneumonia because of its individualized syndrome differentiation. This article uses the Luomai-Xuanweifu theory as a guide to explore the pathogenesis and treatment of viral pneumonia in children. First, the origin of the Luomai-Xuanweifu theory is traced by mining the ancient and modern literature. Secondly, the interpretation of Luomai-Xuanweifu theory is made from the perspective of modern medicine.Based on the pathogenesis and pathological manifestations of viral pneumonia,it is proposed that obstruction of Luo and closure of Xuan is the key to the pathogenesis of viral pneumonia.Finally the treatment method of Tongluo Kaixuan is summarized, which is expected to provide clinical guidance.
