Abstract Tuberculosis transmission has been documented in health care settings where health care providers and patients encounter persons with unsuspected, infectious tuberculosis disease who have not been isolated in a timely manner or have not received appropriate treatment. Initial risk assessment for tuberculosis is crucial for determining administrative, environmental, and respiratory protective measures. Preventing the spread of aerosol-transmissible pathogens requires the use of airborne infection isolation rooms. In addition, respiratory protection with an N95 or higher-level respirator is recommended. Patients with suspected or confirmed respiratory tuberculosis disease should not share rooms.
