Abstract
In healthcare facilities, the initial response to emerging and reemerging infectious diseases, including COVID-19, requires systematic management. The first step is to establish an initial risk assessment and subsequent response flow, using a combination of triage and clinical examination for patients. Screening tests are performed for the early diagnosis of asymptomatic patients who are judged to be at low risk in the initial assessment. However, regardless of the test results, subsequent patient care should be taken cautiously to avoid inadequate initial evaluation at the time of admission, follow-up of symptoms and infection control measures after admission. The basic principle is standard precautions, with particular emphasis on compliance with hand hygiene. Universal masking for preventing transmission from asymptomatic/pre-symptomatic patients and reducing droplet emission and inhalation become the new essential precaution. For suspected/confirmed patients with COVID-19, surgical mask or N95 mask, gloves, gown, eye protection, and cap are basically used. The policy for personal protective equipment is made based on the medical environment of each facility. A negative pressure room is not always required but should be considered in high-risk environments, if possible. While the risk of transmission from the surface environment in a standard healthcare delivery system is limited, a continuous review of the facility environment is expected, considering the importance of ventilation.
