Cough is the most prominent clinical manifestation of novel coronavirus pneumonia. Due to the inflammatory stimulus of the virus there will be respiratory symptoms of coughing, mainly in the form of a dry cough. The cough may be episodic or it may be persistent and irritating. In addition to cough symptoms, some patients may also show fever, chest tightness, shortness of breath, dyspnea, which is a typical clinical manifestation of new coronavirus pneumonia. In some patients, the clinical course may be mild due to strong resistance and relatively low viral load, and may be characterized only by a cough, which is usually dry and may be without fever. If the patient is not tested for nucleic acid, it may be misdiagnosed as a cold. Therefore, for those who have a history of contact with an infected area, or a history of close contact with a patient with novel coronavirus, it is recommended that a nucleic acid test is necessary to clarify whether there is a novel coronavirus infection if respiratory symptoms, including coughing symptoms, are present.
