The main clinical manifestations of novel coronavirus pneumonia are fever, which is present in more than 70%-80% of patients, and cough, which is mostly dry, and dyspnea or shortness of breath, while other manifestations are relatively rare. Upper respiratory tract infections such as sore throat, runny nose, sneezing, nasal congestion accounted for a relatively small proportion. Whether or not nasal congestion alone is a new type of pneumonia with coronary artery disease has to be determined by combining the presence of other manifestations with CT of the lungs and laboratory tests to see if there is a decrease in white blood cells or lymphocytes. In addition to nasal congestion, it is necessary to observe whether there is fever, cough, especially dyspnea, combined with whether there are imaging changes in the lungs, whether there is a decrease in white blood cells, whether there is a decrease in lymphocytes, etc. to consider the combination of the new coronavirus pneumonia. Nasal congestion alone is less likely to be diagnosed as new coronavirus pneumonia, but should be combined with other symptoms, and if you are unable to determine this on your own, it is best to go to the hospital.
