Local airflow patterns, not ventilation alone, can drive airborne tuberculosis spread
Tuberculosis (TB) is a leading cause of infectious disease deaths, claiming more than 1 million lives every year. It spreads through the air when an infected person coughs, sneezes or exhales, and drug-resistant strains and asymptomatic spreading are growing concerns. Curbing TB transmission is an urgent public health challenge, yet scientists still don't understand how airflow and other…
Local airflow patterns, not just ventilation, can significantly impact the spread of airborne tuberculosis, according to a new study involving researchers from MIT and the University of Texas Southwestern Medical Center. The team found that the specific arrangement of air leaks, inflow and outflow points, and forces generated by an infected individual play a crucial role in disease transmission.
Professor Lydia Bourouiba, the lead researcher, emphasized that these local airflow patterns are vital considerations when designing indoor spaces to prevent the spread of respiratory diseases. The findings highlight the importance of accounting for airflow inhomogeneity in building designs, especially in the context of respiratory transmission studies and mitigation strategies.
