Main Results:

  • Ventilation is a primary engineering control for TB.
  • HEPA filtration and UVGI are effective supplements to ventilation.
  • Specific controls are needed for aerosol-generating procedures.

Conclusions:

  • A multi-faceted approach using ventilation and supplementary technologies is key.
  • Engineering controls must be tailored to specific clinical risks.
  • Continued research and implementation of these controls are vital for patient and staff safety.
