Fig. 1. Establishment and operation flow of RTC.

Blue Box (establishment, operation, and close of RTC): The Ministry of Health & Welfare and local governments may decide to establish the RTC. They secure facilities for RTCs and carry out planning, staffing, and resources management.

Orange Box (admission, isolation, and discharge of patients): when a COVID-19 patient is confirmed through screening treatment, the patient management team immediately assesses the severity and assigns a bed. Patients with mild symptoms are admitted immediately after being assigned to RTC, undergoing a basic medical examination, and quarantined until criteria for lifting isolation is satisfied.

RTC = residential treatment center, COVID-19, coronavirus disease 2019.
