Through analysis of ancient and modern traditional Chinese medicine（TCM） literature

it is believed that coronavirus disease 2019（COVID-19） belongs to the category of "dampness toxin plague"

and the prevention and treatment of the disease should be referred to those of TCM epidemics. The disease can be prevented by the three main measures of "strengthening the vital qi"

"avoiding its toxin qi" and "cultivating its spirit"

which can prevent the spread of the epidemic toxin and prevent the epidemic from getting worse. The basic principles of "cutting for reversing" and "supporting the healthy energy for expulsing pathogen" should be taken during treatment

so as to effectively prevent patients from entering critical stage and reduce the mortality.
