METHODS: We conducted a clinical study of 668 patients with asymptomatic infections in which we analyzed the tongue and pulse features in the Shanghai New International Expo Center mobile cabin hospital. The medical records of the patients, including tongue color, tongue coating, and pulse manifestations, were reviewed by healthcare workers. RESULTS: In total, 668 COVID-19 cases were included in the study. Patient age ranged from 5 to 96 years, with a median of 44.0(IQR 33.0-53.0) years. Among the patients, 6.14% had comorbidities. The most common comorbid condition was diabetes(1.65%), followed by hypertension(0.89%), coronary heart disease(0.89%), thrombotic diseases(0.89%), congestive heart failure(0.60%), and stroke(0.45%). Pink-red(75.4%) was the most common tongue color, followed by red(23.4%) and pale red(1.2%). Tongue coating color and thickness were classified as white fur(9.28%), thin and yellow fur(48.65%), white greasy fur(8.98%), yellow greasy fur(24.70%), and less coating(8.39%). In addition, a large number of patients(n = 300, 44.91%) presented superficial and rapid pulses, and 250 patients(37.4%) exhibited a slippery pulse. CONCLUSION: Our preliminary results showed that wind, heat, and dampness were the main etiologies of the severe acute respiratory syndrome coronavirus 2 Omicron(B.1.1.529) variant infection in traditional Chinese medicine. Furthermore, the main symptoms of the disease may be wind-heat invading the lung syndrome or damp-heat with the exuberance of virulence syndrome, which is of most significance in COVID-19 treatment.展开更多
