An airless nose is one of the symptoms of Novel Coronavirus Pneumonia, but an airless nose does not confirm the diagnosis of Novel Coronavirus Infection, and there may be other causes. Novel Coronavirus Pneumonia is an inflammation of the lungs caused by the Coronavirus. Common symptoms include fever, malaise, dry cough, and in a few patients, a runny nose, an airless nose, sore throat, and diarrhea, so an airless nose is a symptom of Novel Coronavirus Pneumonia. Patients can undergo nucleic acid test to determine whether they are infected with novel coronavirus pneumonia, because nasal airlessness may also be caused by other diseases, such as common cold, rhinitis, etc. If the infection of novel coronavirus pneumonia is diagnosed, it needs to be isolated and treated promptly. After the nose is not breathable, pay attention to keep warm, if there is a situation that affects breathing, we should consult a doctor for symptomatic treatment.
