The difference between novel coronavirus pneumonia and a cold is relatively obvious, compared to the difference between coronavirus pneumonia and influenza. The common cold mainly has upper respiratory manifestations such as runny nose, sneezing, and sore throat, and can also have a mild cough and sputum, and can also have systemic manifestations such as fever. Generally, the fever is low or moderate, and it is short-lived, and the cold can recover on its own within 1 week, such as after drinking more water and resting. The main manifestation of novel coronavirus pneumonia is fever, usually moderate and high fever, and there can also be malaise, dyspnea, general malaise, etc. Some patients have respiratory distress, which is rarely seen in common colds. If this happens, especially after 3-5 days, the fever not only does not get better but also worsens, and even dyspnea and other more serious conditions appear, most of them are not common colds, and must be further examined, check whether the blood routine has low white blood cells, low lymphocytes, and then photograph to observe whether there is inflammation inside the lungs, and further do pathogenic screening.
