New crown generally refers to new coronavirus pneumonia, and there are certain sequelae after being treated for positive new coronavirus pneumonia, such as smell impairment, taste impairment, and pulmonary dysfunction. However, due to the variability of individual conditions, it is impossible to generalize. Novel Coronavirus Pneumonia is caused by Novel Coronavirus infection, which is highly contagious and can be spread through respiratory droplets, close contact and indirect contact. Most patients have a good prognosis after standardized treatment. Some patients with novel coronavirus pneumonia may have a series of sequelae. Since the olfactory nerve and the gustatory nerve epithelium, both of which are the main sites of viral infection, the patients may develop olfactory and gustatory disorders. Patients with compromised lung function may continue to have residual lung function problems, such as dyspnea, chest tightness, and panic attacks, which cannot be generalized. It is recommended that patients with novel coronavirus pneumonia should follow the doctor’s instructions for regular follow-up even after cure, so as to understand how the disease is recovering. Tip: In this article, the terms “neocoronavirus pneumonia” and “novel coronavirus pneumonia” were renamed to “novel coronavirus infection” on December 26, 2022, as announced by the National Health Commission.
