Relationship between tongue diagnosis and CoVID-19
Yu et al reported their findings on the relationship between the clinical features and tongue manifestations of 40 cases with the novel coronavirus pneumonia. In the early stage of disease (day 1-2) these patients presented with red tongue body, less coating, and mild symptoms. As the disease progressed (langer than 3 days), the tongue coat of some patients became thick and greasy.
