Dignity Health Libraries COVID-19 Portal: Covid-19

Scientists and engineers with many years of collective research experience related to indoor air quality, aerosol science, aerosol disease transmission, and engineered control systems for aerosols. Our contributors are active researchers investigating aerosol transmission of COVID-19 (see e.g. 1, 2, 3, and 4). Five of us were speakers at the recent Workshop on Airborne Transmission of COVID-19, organized by the US National Academies of Sciences, Engineering, and Medicine (the highest level scientific organization in the US). Three of us are members of a COVID-19 WHO expert group.
