WHO : Indoor airborne risk assessment in the context of SARS-CoV-2
“A means of quantifying the risk of SARS-CoV-2 airborne transmission in a standardized manner (using a standardized model) in residential, public and health care settings is essential to inform non-pharmaceutical risk reduction measures, such as increasing ventilation, air cleaning and disinfection, source control interventions, and controlling the occupancy, as well as to communicate the risk and enable informed decisions by the occupants.”
