Patients with novel coronavirus pneumonia caused by novel coronavirus infection can heal themselves. For the mild and common types, patients can achieve clinical cure by increasing nutrition, strengthening the body’s resistance, improving their immune function, and maintaining a positive and optimistic attitude. For patients with severe and critical illnesses, clinical treatment such as respiratory support techniques, nutritional support and other symptomatic treatments can be provided. The patient’s condition can be converted to the mild and common type and then can be successfully discharged from the hospital, thus novel coronaviral pneumonia is a self-limiting disease.
