MIT Study Shows Indoor Airflow Design Critical to TB Transmission Control

Tuberculosis has claimed more than a million lives each year for generations, spreading invisibly through the air of shared indoor spaces — yet the physical logic of how rooms either harbor or dispel that invisible threat has remained poorly understood. Researchers at MIT and UT Southwestern have now demonstrated, through a marriage of animal experimentation and fluid dynamics modeling, that it is not how much air a building exchanges but how that air actually moves that determines who lives and who does not. The finding reframes infectious disease prevention as a problem of architecture and p
