Coughing all the time, but without fever, is not necessarily new coronavirus pneumonia. Coughing is a common symptom of respiratory diseases and can be caused by many diseases, both infectious and non-infectious. New coronavirus pneumonia can present with cough, chills, fever, sore throat, etc. Cough can be caused by new coronavirus pneumonia, but it can also be caused by other upper respiratory tract infections, bronchitis, tuberculosis, lung tumors, etc. Chest X-ray or chest CT, sputum examination, blood tests, and even bronchoscopy are needed for further identification. If the diagnosis of novel coronavirus pneumonia is suspected, nucleic acid testing will be performed, and if the diagnosis of novel coronavirus pneumonia is confirmed, isolation treatment will be required.
