Novel coronavirus infection has the potential to heal on its own. Novel coronavirus pneumonia is divided into light and heavy. If the patient is light, with symptoms related to upper respiratory tract infection, such as pain in the throat, cough and sputum, and no significant changes in chest CT, he can first be observed in isolation at home, and some patients can heal on their own. If it is a heavy patient, because the disease progresses faster and the condition is more serious, it needs to go to the hospital for isolation, rescue and standardized treatment in time.
