Second, the local symptoms of respiratory tract, only a small number of patients with new crown pneumonia have khat symptoms, including nasal congestion, runny nose, sore throat. Patients with cold have mainly respiratory cata symptoms, with obvious nasal congestion, runny nose, cough and throat discomfort. Third, the temperature situation, the new crown pneumonia with fever as the first symptom, persistent high fever patient’s condition is more serious. Fever is not always present in the case of colds, and even if fever is present, the fever duration is short.

A cold does not have dyspnea and hypoxemia, and it basically heals after one week with clinical remission.
