Outbreaks of COVID-19 have resulted in the dissemination of the virus in the community. A study conducted by The Jockey Club School of Public Health and Primary Care of the Faculty of Medicine at The Chinese University of Hong Kong (CU Medicine) showed that other than the infectiousness of the source, the physical setting where the infection was transmitted played a key role in the propagation of the virus in society. In the first two waves of the outbreak in Hong Kong, entertainment venues accounted for the highest number of local primary setting transmissions and were linked with the widest range of subsequent cascades of transmissions settings.

This finding is critical for controlling the spread of COVID-19 in the community. The research article “Settings of virus exposure and their implications in the propagation of transmission networks in a COVID-19 outbreak” was published in the latest issue of the Lancet Regional Health – Western Pacific: https://authors.elsevier.com/sd/article/S2666606520300523.
