Patients with active TB should be assigned to single-patient rooms in which the entry of HCWs and visitors is controlled.
All HCWs who have the risk of coming into contact with TB patients or TB specimens should use either an N95 disposable respirator or a reusable powered air-purifying respirator (PAPR) that can be cleaned, disinfected, and reused. (A PAPR uses a blower to pass contaminated air through an approved HEPA filter, supplying purified air to the facepiece.)
Visitors may be offered respiratory protection (e.g., N95) and should be instructed by HCWs on the use of the respirator before entering the AII room.
The AII room has requirements for controlled ventilation, negative pressure, and air filtration.
Each isolation room should have a private bathroom.
