In one embodiment, a prefabricated container is modified as a medical isolation room by replacing an original door with a clear front door. An intake louver and an adjustable damper are disposed at a lower part of the front end. An exhaust vent is disposed at an upper part of the back wall. An exhaust fan and a HEPA filter are coupled to the exhaust vent. Washable coverings cover interior sides of the container to provide washable, nonslip interior surfaces. The exhaust fan and the adjustable damper at the intake louver are controlled to produce in the medical isolation room a negative air pressure of at least about minus 0.01 inch of water gage (approximately 2.5 pascals) and a displacement ventilation exhaust flow rate through the exhaust vent of at least about 100 cubic feet per minute (cfm) greater than an intake flow rate through the intake louver.
