HOK Chief Medical Officer Andrew Ibrahim, MD, MSc, has collaborated with Joseph G. Allen, DSc, MPH, assistant professor at the Harvard T.H. Chan School of Public Health, on an article examining the potential impact of indoor air changes on SARS-CoV-2 transmission.
Excerpted from JAMA Network:
Buildings have been associated with spread of infectious diseases, such as outbreaks of measles, influenza, and Legionella. With SARS-CoV-2, the majority of outbreaks involving 3 or more people have been linked with time spent indoors, and evidence confirms that far-field airborne transmission (defined as within-room but beyond 6 feet) of SARS-CoV-2 is occurring.
Increasing air changes per hour and air filtration is a simplified but important concept that could be deployed to help reduce risk from within-room, far-field airborne transmission of SARS-CoV-2 and other respiratory infectious diseases. Healthy building controls like higher ventilation and enhanced filtration are a fundamental, but often overlooked, part of risk reduction strategies that could have benefit beyond the current pandemic.
