“Although transmission via the shared elevator cannot be excluded, this event is consistent with the findings of the Amoy Gardens SARS outbreak in Hong Kong in 2003,” Song Tang, a scientist with the China CDC Key Laboratory of Environment and Population Health, and colleagues wrote in the study, which cited unpublished data from the health agency.

Apartments in multistory buildings may be linked via a shared wastewater system, said Lidia Morawska, director of the International Laboratory for Air Quality and Health at Australia’s Queensland University of Technology. While solids and liquids descend the network, sewer gases — often detectable by their odor — sometimes rise through pipes in the absence of sufficient water, said Morawska, who wasn’t part of the research team.
