Whether or not there are sequelae of novel coronavirus pneumonia is determined by the type of the disease, which clinically includes asymptomatic, mild, common, severe, or critical infections. 1. Asymptomatic infected patients and mild type: After discharge from the hospital, patients usually have no lung function damage and less physical dysfunction. 2. Ordinary type: There are no after-effects after cure, but some patients have symptoms such as fatigue, loss of taste and smell, anxiety, etc., which can be recovered in most cases. 3. Heavy or critical type: some patients still have pulmonary fibrosis after cure. This is because the interstitial lesions in the lungs are more serious when the disease is more severe. People with severe infections may have generalized weakness and shortness of breath, resulting in limited physical function, and lung function is characterized by restrictive ventilatory deficits, and this change may persist. Symptoms such as cough and shortness of breath may occur during subsequent recovery recuperation. For pulmonary fibrosis in individual patients with severe disease, recovery takes longer. In addition, the sequelae of novel coronavirus pneumonia require extensive case summarization and observation. [Note: In this article, the terms “new coronavirus pneumonia” and “new coronavirus pneumonia” were renamed to “new coronavirus infection” on December 26, 2022, as announced by the National Health Commission.
