COVID-19 Outbreak Associated with Air Conditioning in Restaurant, Guangzhou, China, 2020

Abstract

During January 26-February 10, 2020, an outbreak of 2019 novel coronavirus disease in an air-conditioned restaurant in Guangzhou, China, involved 3 family clusters. The airflow direction was consistent with droplet transmission. To prevent the spread of the virus in restaurants, we recommend increasing the distance between tables and improving ventilation.

Keywords: 2019 novel coronavirus disease; COVID-19; SARS-CoV-2; droplet transmission; family cluster; outbreak; respiratory infections; restaurant; severe acute respiratory syndrome coronavirus 2; viruses; zoonoses.
