The new type of pneumonia should refer to the new type of coronavirus pneumonia, which may be characterized by nasal congestion, but the presence of nasal congestion does not indicate infection with the new type of coronavirus. The new coronavirus can invade the mucous membranes of the respiratory tract of the human body, thus triggering symptoms such as nasal congestion and runny nose. However, the main respiratory symptom in patients with novel coronavirus pneumonia is a dry cough. Typical symptoms are fever, malaise, dry cough, accompanied by loss of taste and smell in some patients, and nasal congestion in a few. In addition to novel coronavirus infection, possible causes of nasal congestion include nasal irritation such as pollen allergy, dust inhalation during cleaning, hot and cold irritation, rhinitis and common cold. If you have been exposed to a novel coronavirus-positive environment and the above symptoms occur at the same time, you need to report it and seek medical attention promptly. [Note: On December 26, 2022, the National Health Commission announced that the terms “new coronavirus pneumonia” and “new coronavirus pneumonia” were renamed to “new coronavirus infection” in this article.
