Restrict the number of personnel entering the room of a patient with suspected or confirmed COVID-19. If possible, isolating suspected cases separately from confirmed cases may also help prevent transmission. Administrative ControlsĬonsistent with the general interim guidance, isolate patients with suspected or confirmed COVID-19 to prevent transmission of the disease to other individuals. The CDC/Healthcare Infection Control Practices Advisory Committee (HICPAC) Guidelines for Environmental Infection Control in Healthcare Facilities contain additional information on negative-pressure room control for airborne infection isolation. Ensure that the room air exhausts directly to unoccupied areas outside of the building, or passes through a HEPA filter, if recirculated. Isolation tents or other portable containment structures may serve as alternative patient-placement facilities when AIIRs are not available and/or examination room space is limited. If available, negative-pressure rooms (i.e., rooms under negative pressure that may not meet all of the specifications of an ideal AIIR) are preferable to ordinary exam or patient rooms. Not available: Isolate the patient in a private room.Ensure that the room air exhausts directly to unoccupied areas outside of the building (i.e., not into walkways, break areas, or other areas where workers or visitors could congregate or pass through), or passes through a high-efficiency particulate arrestance (HEPA) filter, if recirculated. Perform aerosol-generating procedures on patients with suspected or confirmed COVID-19 in an AIIR.
