Novel pneumonia is an acute respiratory infection caused by a novel coronavirus, which is self-healing in patients with mild symptoms and strong autoimmune function. However, because the new coronavirus is highly infectious and progresses rapidly, treatment should be given promptly even if the symptoms are mild. Patients should rest in bed, keep warm, and maintain electrolyte balance in the body to avoid deterioration and delay of treatment. For patients with severe symptoms, especially those with severe lung tissue damage, respiratory distress, septic shock and other serious symptoms, they cannot recover on their own and should be treated with resuscitation if necessary.
