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.

摘要： 目前，我国新型冠状病毒肺炎（COVID-19）疫情趋于基本控制，但在全球多地COVID-19疫情仍持续蔓延的形势下，越来越多的国内外研究数据显示，严重呼吸综合征冠状病毒2（SARS-CoV-2）感染者中存在一定数量的新型冠状病毒无症状感染者（ACIC），且具有传染性。由于无明显临床症状及体征，ACIC给疫情防控及传统中医辨证论治带来极大挑战。本文分析了ACIC的分类、病机、中医辨证思维方法及论治原则，总结认为ACIC虽在宏观上“无症可辨”，基层医务工作者仍可通过微观辨证、辨病、辨体质及“治未病”等进行辨证论治。
