Two days prior, the patient experienced fever, cough with scanty phlegm that was difficult to expectorate, accompanied by fatigue, poor appetite, pale red tongue with white coating. Chest CT revealed scattered patchy and large ground-glass opacities in both lungs. Blood routine results showed a significantly decreased absolute lymphocyte count.

The patient received standard treatment with Western medicine for infection control and phlegm reduction, as well as traditional Chinese medicine treatment for nourishing vital energy and clearing lung heat for one week, with no significant improvement in symptoms. Given the complexity of the patient's condition, a remote consultation was sought with Professor Gu Xiaohong.
