Topic:

  • An outbreak of SARS-CoV-2 among 10 people from 3 family units was linked to an indoor air-conditioned restaurant in Guangzhou, China. Examination of the potential routes of transmission suggest that the most likely cause of this outbreak was droplet transmission from one asymptomatic index patient. The authors recommend increasing the distance between tables and improving ventilation to prevent the spread of SARS-CoV-2 in restaurants.
