COVID-19, Aerosols, and Ventilation

As we continue through these winter months, we find ourselves inside for longer periods of time. How can we avoid aerosolized droplets becoming a problem for disease transmission in our public buildings? We have many layers to consider for minimizing risk, but in many ways it starts with the ventilation systems in these buildings. To learn more about the connection between air ventilation and the COVID-19 pandemic, we spoke with Dr. Aurora Le, assistant professor of Environmental Health Sciences at the School of Public Health and an expert on biocontainment and biosafety procedures. According to the Centers for Disease Control and Prevention (CDC) and many other public health experts, close contact with another person, and specifically through the spread of respiratory droplets is considered the primary cause of infection from COVID-19. However,mounting evidence points to aerosolized droplets—much smaller droplets that remain in the air, sometimes for hours—as a concerning source of transmission for coronavirus, especially in what are known as superspreader events, where many people are infected by just a few or even one known source.
