Patient data are presented as number (%) or mean (range).
Degree of disease severity: For the mild type: slight clinical symptoms with no pneumonia presentation in imaging. For the common type: manifestations such as fever or respiratory presentation with pneumonia by radiography, or both. For the severe type (meeting any of the following conditions): (1) dyspnea, respiration rate 30 times/min; (2) finger oxygen saturation under resting 93%; (3) arterial partial pressure of arterial oxygen/fraction of inspired oxygen 300 mm Hg (1 mm Hg = 0.133 kPa). For the critical type (meeting any of the following conditions): (1) respiratory failure requiring mechanical ventilation; (2) shock; (3) combined with other organ failures requiring an intensive care unit.
