Which disease is a classic example of airborne transmission requiring an AIIR?

• A. Mumps
• B. Influenza
• C. Rubella
• D. Tuberculosis

Answer: (D)

Airborne transmission involves tiny particles that can remain suspended in air and travel long distances on air currents. The bacterium causing tuberculosis is carried in droplet nuclei small enough to stay airborne for extended periods, which is why controlling its spread relies on airborne precautions. An Airborne Infection Isolation Room is designed with negative pressure relative to adjacent areas, ensuring airflow moves into the room but not out into the rest of the facility. The room is often equipped with specialized ventilation and filtration (and doors kept closed) to prevent contaminated air from escaping and to protect other patients and staff. This combination—susceptibility to airborne spread and the need for strict negative-pressure isolation—is what makes tuberculosis the classic example requiring AIIR.
