Imported novel coronavirus pneumonia is a disease that occurs when a patient from elsewhere arrives in a living area where there was no pneumonia before, so it is called imported novel coronavirus pneumonia. If a patient from Wuhan comes to Beijing, making a case of novel coronavirus pneumonia diagnosed in Beijing, this type of patient is considered to be imported novel coronavirus pneumonia. Once the imported coronavirus pneumonia patient infects other comrades in Beijing who have not been to Wuhan, it will make the amount of patients bigger and bigger. The latter type of patients do not belong to imported novel coronavirus pneumonia, but to locally occurring novel coronavirus pneumonia, and patients coming from Wuhan belong to imported patients.
