How to inquire the medical record number of COVID-19 case?

Please go to the window to check the medical record number of COVID-19's case. The medical record number needs to be queried in the hospital window. The medical record number is issued by the inpatient clinic, and the hospitalization number is a number given by the patient when registering for hospitalization. If a hospital system is done well, the same patient can only use one hospitalization number at a time, which can facilitate the hospitalization of patients.
