It is possible for some patients infected with novel coronavirus pneumonia to recover spontaneously, as described below. If the patient is usually in good health and has mild clinical symptoms after infection with the new coronavirus, such as only a mild low-grade fever, cough and other symptoms, or some of the patients are asymptomatic infected, neither have symptoms, nucleic acid test appears positive, then it is possible to recover without treatment. However, for patients with severe or critical forms of novel coronavirus pneumonia, the condition develops more rapidly, and serious complications such as respiratory failure and sepsis may occur, requiring prompt treatment to avoid life-threatening conditions. The new coronavirus is highly transmissible, so once found, it needs to be isolated in time for observation and treatment, and should not be isolated at home and wait for self-healing.
