The cough characteristic of novel pneumonia is more severe compared to that of the common cold. The cough and sputum may appear only at a later stage of the common cold, while the new coronavirus pneumonia cough is very severe and mainly dry. It may even cause patients to go into shock. So the cough of new coronavirus pneumonia is still serious, so pay extra attention to your own protection, try not to cough at others when coughing, use your own elbow to protect your mouth, wear a mask more often, pay attention to ventilation and hand washing, etc. Content source: Dr. You Lai
