One aerosol-generating procedure. Three colleagues exposed. A preventable outcome with proper respiratory protection.
Tuberculosis is airborne, and healthcare workers face heightened exposure risk - especially during aerosol-generating procedures. The 2019 CDC/NTCA guidelines changed screening recommendations significantly. EZBunny's course covers what your clinical team needs to know about TB transmission, screening, respiratory protection, and isolation procedures.

Which roles must complete this training?
Clinical staff with patient contact, especially in high-risk settings:

- Respiratory Therapists: Highest exposure risk during aerosol-generating procedures
Common TB prevention training questions
What changed with the 2019 CDC/NTCA TB screening guidelines?
The 2019 guidelines shifted away from routine annual TB testing for healthcare workers in most settings. Instead, they recommend individual risk assessments and testing based on known exposures or work in high-risk settings. Baseline testing at hire is still recommended. This replaced the previous one-size-fits-all annual testing approach with a more targeted strategy.
What's the difference between LTBI and active TB disease?
LTBI means you carry TB bacteria but are not infectious and have no symptoms. Active TB disease means the bacteria are multiplying, causing symptoms (cough, fever, weight loss), and the person is potentially infectious. LTBI can progress to active disease - which is why treatment is recommended, especially for healthcare workers who face repeated exposure risk.
When is an N95 respirator required?
An N95 (or higher) respirator is required when entering the room of a patient with suspected or confirmed active pulmonary TB. It is also required during any aerosol-generating procedure on such patients. Surgical masks are NOT adequate for TB protection - TB particles are small enough to pass through surgical mask material. Healthcare workers must be fit-tested for their N95 respirator annually.
What is an airborne infection isolation room (AIIR)?
An AIIR is a single-patient room with negative air pressure relative to surrounding areas. It requires a minimum of 6-12 air changes per hour and air that is exhausted directly outside or through HEPA filtration. Patients with suspected or confirmed active pulmonary TB should be placed in an AIIR. If no AIIR is available, the patient should be transferred to a facility that has one.
