What surface area do airborne precaution protocols primarily target?

Airborne precaution protocols primarily target small particles suspended in the air. These small particles, which can remain airborne for extended periods and travel over distances, are often associated with infectious agents that can be transmitted when inhaled. This is especially important for diseases such as tuberculosis, measles, and chickenpox, which can be spread through aerosols.

By focusing on these small airborne particles, airborne precaution protocols emphasize the need for specialized interventions, such as the use of N95 respirators or other forms of respiratory protection, proper ventilation in care areas, and specific room designs for isolation. These strategies are crucial for minimizing infection risk in healthcare settings, particularly where patients with known airborne infections are present. The measures aim to create an environment where the risk of airborne transmission is significantly reduced, protecting both healthcare workers and other patients.
