Patients are isolated to prevent the spread of disease to other people in the medical environment. Isolated persons are typically either highly contagious or infected by a treatment-resistant organism. Isolated persons may also be those who are immunosuppressed. Medical personnel visit isolated patients regularly and wear additional protection such as gowns and gloves.
