Yuguo Li, PhD, Professor, Department of Mechanical Engineering, Associate Dean, Faculty of Engineering. University of Hong Kong, "Transmission of SARS-CoV-2: Respiratory and fecal aerosols"

Nine months into the pandemic, many aspects of the transmission of COVID-19 are still unclear. Transmission via aerosols (less than 75 μm diameter) is undoubtedly the main path. Aerosols originating from a respiratory source are hereby most dangerous within a distance of 1.5 m, where aerosol concentration is high and the size is just right for aspiration. He presents his investigation of three different infection events, in a Wuhan restaurant and bus, on the Diamond Princess cruise ship and Amoy Garden, a building complex. Besides respiratory aerosols, the latter example demonstrates the risk of faecal aerosols and their distribution.
