Cough with sputum is not necessarily novel coronavirus pneumonia. The most common symptoms of novel coronavirus pneumonia are fever and cough, while most people have only a dry cough with no sputum in the early stages. If coughing with sputum occurs early, it may not be novel coronavirus pneumonia. If the symptoms of cough and sputum worsen after 1 week and the symptoms of dyspnea worsen, consider the possibility of novel coronavirus pneumonia. Because cough and sputum are actually seen in various respiratory diseases, such as cold, flu, asthma, and chronic bronchitis, which may have cough and sputum symptoms all year round, they cannot all be diagnosed as novel coronavirus pneumonia. New coronavirus pneumonia must be based on the epidemiological history. If you come in contact with the patient, or if you develop fever and cough symptoms after going to Wuhan, Hubei, you should be highly suspicious of new coronavirus pneumonia. At this time, you must go to the hospital to do the relevant tests, such as routine blood, chest CT, pharyngeal swab nucleic acid test. Content source: Dr. You Lai
