In terms of clinical manifestations, patients with novel coronavirus pneumonia seldom have symptoms of runny nose, and the incidence is not very high. For patients with new coronavirus pneumonia fever is the most important manifestation, can be combined with mild dry cough, fatigue, etc., and later there may be dyspnea, diarrhea and other symptoms, runny nose, cough, nasal discharge and other catarrhal symptoms are relatively rare. If this is only present, without other clinical manifestations, the suspicion of other diseases will be more. After this, half of the new crown pneumonia infections may develop respiratory distress, and in severe cases may quickly progress to acute respiratory distress syndrome, which may be difficult to correct with metabolic acidosis such as septic shock. If only a runny nose or no other corresponding symptoms or can not be carried out to confirm the diagnosis, there is still a high probability that it is not a new type of coronary pneumonia, and you do not need to be too nervous and anxious.
