CityU experts explain the distribution of airborne aerosol droplets emitted from toilet flushing and its relationship with transmission of pathogens

We would like to invite you to cover the following event:

The spread of the novel coronavirus in indoor habitats has presented challenges to disease prevention. Professor Alvin Lai Chi-keung, Associate Head of the Department of Architecture and Civil Engineering, College of Engineering, City University of Hong Kong (CityU), and his research team have researched the relationship between airborne aerosol droplets and the transmission of pathogens for many years. In particular, the flow of aerosol droplets and bacteria emitted from toilet flushing have been extensively studied.

Professor Lai will introduce his research findings at the press conference, including the numbers and sizes of airborne aerosol droplets emitted from toilet flushing, and the distribution of these droplets in the air and the nearby environment. 

Dr Eric Lee Wai-ming, Associate Professor of the Department of Architecture and Civil Engineering, CityU, will provide supplementary information on the relationship between sewage systems and hygiene conditions in indoor environments.

Professor Lai will incorporate the findings of his research team and international academic studies and suggest ways to keep clean and reduce contamination in washrooms. A member of the research team who is also a specialist in infectious disease, Dr Iris Li Wai-sum, will also attend the press conference.
