Ventilation as a Key Defense Against Infectious Diseases

In this session, we deep-dived the pivotal role of ventilation in maintaining healthy indoor environments and discussed its effectiveness as a tool against spreading infectious diseases. By delving into the nuances of effective ventilation systems, we provided a comprehensive understanding of how these systems can be used strategically in various settings to mitigate the risk of infectious disease transmission.

IBEC and the Commit 2 C.A.R.E program focus on the 4D’s to reduce the spread of airborne infectious disease. These are Distance, Density, Duration, and Dilution. Ventilation dilutes airborne contaminants, including aerosols, the particles that carry a pathogen from an infected to an uninfected person. Adjusting ventilation in our indoor spaces can reduce the long-range spread of airborne disease. This is an important control measure as we face an increasingly diverse range of respiratory infections with high transmissibility carried through the air and our air conditioning systems.

The session featured a panel of distinguished experts from Virginia Tech University, InAIR Environmental, SafeTraces, Inc., Johnson Controls, and The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE). These panelists brought a wealth of knowledge in air quality, bioengineering, and occupational hygiene, and their insights were invaluable in guiding our discussions and strategies toward healthier, safer environments.
