In patients with novel coronavirus pneumonia, the main clinical manifestations are cough, fever and progressive dyspnea. Cough is the very dominant clinical manifestation. Some mildly ill patients may present only with a cough and no fever, and the severity of the cough is closely related to the severity of the lesion and the extent of the lesion. Some patients show only mild symptoms of respiratory infection, similar to cold symptoms, and may have a mild cough, or an occasional cough. Some patients have a more intense inflammatory response and more extensive lung lesions, and may have a persistent, severe cough, so the degree of coughing varies from person to person.
