Chest-computed tomography of the patient on February 4, 2020, showed signs of infection indicating the possibility of viral pneumonia (A). Continuous chest digital radiography during treatment from February 10 to March 2 (B).

COVID-19 was performed immediately. Chest-computed tomography (CT) showed diffuse ground-glass opacities in the periphery of bilateral lungs, which represented the characteristic imaging for pneumonia of COVID-19 (Figure 1). We observed faded imaging and restoration of organic function after treatment (Figure 1). Although the chest DR showed progress on February 27 (Figure 1), the patient's condition worsened, and he died on March 4.
Continuous analysis of blood cells and blood gas during treatment: normal white blood cell count, 4.0-10.0 x 109 cells/L; normal lymphocytes, 1.1-3.2. x 109 cells/L; normal C-reactive protein, <5 mg/L; normal oxygenation index (>400 mmHg); normal PCO2 (<50 mmHg); and normal lactic acid, 0.2-1.4 mmol/L. The black symbols indicate the result is in the normal range, the red symbols indicate the results are above the normal range, and the blue symbols indicate the results are below the normal range.

Blood tests revealed that the white blood cell count was 4.92 x 109 cells/L (normal: 4.0-10.0 x 109 cells/L), lymphocyte (LY) was 1.1 x 109 cells/L (normal: 1.1-3.2 x 109 cells/L), C-reactive protein (CRP) was 118.24 mg/L (normal: <5 mg/L), and pathogenic findings of common respiratory viruses and influenza A and B viruses were negative (Figure 2). However, the patient's respiratory distress and fatigue did not relieve, and CRP levels increased to 124.2 mg/L on February 11 (Figure 2). We changed to a superior antibiotic after blood test results showed leukocytosis (26.17 x 109 cells/L), lymphopenia (0.52 x 109 cells/L), and elevated CRP levels (170.2 mg/L) (Figure 2). However, on February 17, the urine volume was 1,100 mL, and renal failure occurred, with elevated blood urea nitrogen (25.24 mmol/L, normal: 3.2-7.1. mmol/L) and creatinine (395.2 mumol/L, normal: 44.0-133.0 mumol/L) levels (Figure 2).
