Abstract: Against the backdrop of COVID-19 pandemic tending to be basically contained in China but continuously spreading in many other countries，increasing studies have found that there is a certain amount of asymptomatic cases infected with coronavirus，and they are contagious，whose diagnoses have posed great challenges both to COVID-19 containment and TCM syndrome differentiation and treatment due to lack of obvious clinical symptoms and signs.We analyzed the syndrome classification，pathogenesis，perspectives and principles of TCM syndrome differentiation for asymptomatic cases infected with coronavirus，and proposed that such cases could be diagnosed and treated by micro syndrome differentiation，disease identification，constitutional differentiation，and “preventive treatment of disease”and so forth，even if without symptoms macrocosmically.
