Community evidence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission through air.

ABSTRACT:

Background

Nine COVID-19 (Corona Virus Disease, 2019) cases were observed in one community in Guangzhou. All the cases lived in three vertically aligned units of one building sharing the same piping system, which provided one unique opportunity to examine the transmission mode of SARS-CoV-2.

Methods

We interviewed the cases on the history of travelling and close contact with the index patients. Respiratory samples from all the cases were collected for viral phylogenetic analyses. A simulation experiment in the building and a parallel control experiment in a similar building were then conducted to investigate the possibility of transmission through air.

Results

Index patients living in Apartment 15-b had a travelling history in Wuhan, and four cases who lived in Apartm
