Abstract: words)Main text (3456 words) AbstractBackground: The role of aerosols in the transmission of SARS-CoV-2 remains debated. We analysed an outbreak involving three non-associated families in Restaurant X in Guangzhou, China, and assessed the possibility of aerosol transmission of SARS-CoV-2 and characterize the associated environmental conditions. : medRxiv preprint 2 Methods: We collected epidemiological data, obtained a video record and a patron seatingarrangement from the restaurant, and measured the dispersio… Show more

“…SARS‐CoV‐1 and SARS‐CoV‐2 both target the surface receptor angiotensin‐converting enzyme‐2 (ACE‐2) in humans as a means of entry, 24,25 and ACE‐2 is expressed on type II pneumocytes in the lung 26,27 and ciliated cells of nasal mucosa, 27,28 suggesting that there is a biologically plausible mechanism for an airborne route of transmission. Observational studies and models are emerging suggesting airborne transmission of SARS‐CoV‐2 can occur 29‐31 …”

“…Several case studies have suggested efficient SARS-CoV-2 transmission due to aerosols. A study in Wuhan, China, found significant aerosol spread of SARS-CoV-2 in a restaurant with $0.8 air changes per hour (Li et al 2020;Lu et al 2020). At the same time, the aerosol spread was found to be highly localized to the particular zone covered by a single air-handling unit (AHU), without identified spread to portions of the room under the control of other AHUs or to waiters moving in and out of the region of contaminated air (Li et al 2020).…”

This observation has important implications for shared work in the same laboratory room, e.g., if sufficient air flow and separation between areas can be maintained when two workers occupy the same room (see "Results and Discussion").…”

“…In the current pandemic, ventilation practices should be reviewed, and ventilation maximized (Morawska and Cao, 2020), especially in closed and crowded settings such as canteens and restaurants. Tracer gas measurements and computational fluid dynamics (CFD) simulations were used to predict the spread of fine droplets exhaled by the index patient and the detailed airflow pattern at the restaurant outbreak in Guangzhou (Li et al ., 2020b). The authors observed that high concentration of the simulated contamination resulted from lack of outdoor supply.…”
