Abstract：From the perspective of the theory of febrile diseases and based on the clinical practice of the treatment of COVID-19,this paper systematically discusses the name of the disease in traditional Chinese medicine,the types of disease,the attributes of etiology,the changes of pathogenesis,the methods of syndrome differentiation,the treatment principles and methods,and the application of prescriptions.It is considered that COVID-19 belongs to the infectious febrile disease of febrile diseases,and its etiological attribute is the qi of dampness-heat pestilence.Pathogenic factor enters from the mouth and nose or fur,and it is latent in the lung and spleen when the healthy qi is in deficiency,and it can be recognized and treated as a latent febrile disase.The qi of dampness-heat pestilence can be spontaneous in the interior,or induced by external evil,and stay in the qi aspect for a long time,forming the syndrome of dampness superior to heat,both dampness and heat,heat superior to dampness.The dampness and heat pestilence may permeate the heart,brain,tongue,nose,ears and other upper orificums.During or after the pathological process,according to the degree of dampness and heat,both yin and yang can be damaged.It mainly involves the lungs,spleen,heart and kidneys.The main pathological factors are dampness,heat,deficiency and blood stasis.The basic treatment principle is strengthening the body resistance to eliminate pathogenic factors and driving away pathogenic factors,and different treatments and prescription drugs are given according to the severity of dampness-heat and the nature of the pathogenic factors.The common cases of fever,cough,fatigue and insomnia in different stages of the disease are cited,and the ideas of diagnosis and treatment are analyzed.
