The mean age of the 55 patients in our study was 46·8 years. Among them, 30 (54·55%) were male, 28 (50·91%) had been in Wuhan/Hubei, and 19 (34·55%) were complicated with other chronic diseases. Lung computed tomography scans showed local or diffuse infiltration shadows in 54 patients (98·18%), whereas the remaining patient (1·82%) had no inflammatory changes. There were 47 patients (85·45%) in the mild group and eight (14·55%) in the severe group ( Table 1) . The most common symptoms of COVID-19 were fever 32 (58·18%) and cough 27 (49·09%). Seventeen patients (30·91%) were complicated with liver function impairment, 15 (27·27%) with hypoxemia, and two (3·64%) with acute respiratory distress syndrome (ARDS) ( Table 2 ). The white blood cell counts, lymphocyte counts, and percentage of lymphocyte counts of patients in the mild group were in the normal range, although C-reactive protein levels (15·73 mg/L) were elevated. In the severe group, however, lymphocyte counts (0·78 × 10 9 /L) and the percentage of lymphocytes (12·30%)
