Abstract

To determine possible modes of virus transmission, we investigated a cluster of coronavirus disease cases associated with a shopping mall in Wenzhou, China. Data indicated that indirect transmission of the causative virus occurred, perhaps resulting from virus contamination of common objects, virus aerosolization in a confined space, or spread from asymptomatic infected persons.

Keywords: 2019 novel coronavirus disease; COVID-19; China; SARS-CoV-2; Wenzhou; aerosolization; cluster; coronavirus; respiratory infections; severe acute respiratory syndrome coronavirus 2; viruses; zoonoses.
