The results of TSS are shown in Fig. 1. Score of mild type was 0, while common type was 1–11 (median 5, P25 2.75, P75 6.25) and severe-critical type was 8–18 (median 10, P25 9, P75 15.25). The score of severe-critical type was significantly higher than common type (p < 0.001). Figures 2 and 3 were from common-type and severe-critical-type patients, respectively.
Fig. 1 The total severity score (TSS) of different clinical classifications. There were 24 cases of light type (31%), 46 cases of common type (60%), and 8 cases of severe-critical type (9%). The median TSS was 10 in severe-critical-type group (range 8–18), which was significantly higher than that of common type (median 5, ranged 1–11)
Fig. 2 A 32-year-old female had fever, cough, and sputum with a body temperature of 38.8 °C for 5 days and admitted to the hospital on Jan. 27, 2020. The leukocytes and lymphocytes were decreased. She was living in Zhuhai and traveled to Wuhan on Jan. 21 and stayed there for 2 days. She was healthy and nonsmoker. Chest CT (images a–c) on the 1st day after admission demonstrated bilateral peripheral ground-glass opacities with linear opacities. TSS was 5. The clinical type was common type. Follow-up CT (images d, e) on the 20th day after onset showed peripheral shrinking consolidation with ground-grass opacities in both lungs
Fig. 3 A 60-year-old male was admitted to the hospital 5 days after fever and cough with a body temperature of 38 °C. The leukocytes were normal and lymphocytes were decreased. He was living in Wuhan and traveled to Zhuhai for the Spring Festival 5 days before the onset of the disease. He had tuberculosis. Chest CT (images a–c) on the 2nd day after admission demonstrated bilateral peripheral ground-glass opacities with minimal consolidation. TSS was 17. The clinical type was severe-critical type. Follow-up CT (images d, e) on the 32nd day after onset showed bilateral fibrotic changes with ground-grass opacities with a left shift of mediastinum
