Nancy H. L. Leung,Daniel K.W. Chu,Eunice Y.C. Shiu,Kwok-Hung Chan,James J. McDevitt,Benien J.P. Hau,Benien J.P. Hau,Hui-Ling Yen,Yuguo Li,Dennis K. M. Ip,J. S. Malik Peiris,WH Seto,WH Seto,Gabriel M. Leung,Donald K. Milton,Benjamin J. Cowling +15 more
TL;DR: A study of 246 individuals with seasonal respiratory virus infections randomized to wear or not wear a surgical face mask showed that masks can significantly reduce detection of coronavirus and influenza virus in exhaled breath and may help interrupt virus transmission.
Journal ArticleDOI
Evidence of Airborne Transmission of the Severe Acute Respiratory Syndrome Virus
Ignatius Tak-sun Yu,Yuguo Li,Tze Wai Wong,Wilson W.S. Tam,Andy Chan,Joseph H.W. Lee,Dennis Y.C. Leung,Thomas C. Ho +7 more
TL;DR: Airborne spread of the virus appears to explain this large community outbreak of SARS in Hong Kong, and future efforts at prevention and control must take into consideration the potential for airborne spread of this virus.
Journal ArticleDOI

TL;DR: It is argued that existing evidence is sufficiently strong to warrant engineering controls targeting airborne transmission as part of an overall strategy to limit infection risk indoors, and that the use of engineering controls in public buildings would be an additional important measure globally to reduce the likelihood of transmission.
Journal ArticleDOI
Size distribution and sites of origin of droplets expelled from the human respiratory tract during expiratory activities
Lidia Morawska,Graham R. Johnson,Zoran Ristovski,Megan Hargreaves,Kerrie Mengersen,Stephen Corbett,Christopher Y.H. Chao,Yuguo Li,David Katoshevski +8 more
TL;DR: In this article, a new expiratory droplet investigation system (EDIS) was used to conduct the most comprehensive program of study to date, of the dilution corrected droplet size distributions produced during different respiratory activities.
Journal ArticleDOI
How far droplets can move in indoor environments--revisiting the Wells evaporation-falling curve.
TL;DR: The results indicate that a droplet's size predominately dictates its evaporation and movement after being expelled, and there is a need to examine the air distribution systems in hospital wards for controlling both airborne and droplet-borne transmitted diseases.
