After the new crown is diagnosed and cured, there may be sequelae, which can be categorized according to the degree of severity of the disease, such as mild and critical types. 1. Mild: These mild patients have mild lung problems after diagnosis and cure of neocoronaryngitis, and no other sequelae have been reported. 2. Critically ill: These patients are mostly those who have been cured of severe cases of neocoronary pneumonia, with sequelae including generalized weakness, shortness of breath, restrictive ventilation disorders, and pulmonary fibrosis. Because of the short period of time since the emergence of C.N.C.P., the research on C.N.C.P. as well as the treatment of its sequelae are not perfect at present. Patients infected with C.N.C.P. should receive the relevant treatment from professional medical institutions, and with the passage of time and the deepening of the research, the sequelae caused by C.N.C.P. may receive more perfect treatment. Tip: The terms “new coronavirus pneumonia” and “new coronavirus pneumonia” mentioned in this article were renamed to “new coronavirus infection” on December 26, 2022, as announced by the National Health Commission.
