Ventilation can "affect disease transmission." 

On Tuesday March 17th, 2020, the National Institutes of Health reported that "The virus that causes coronavirus disease 2019 (COVID-19) is stable for several hours to days in aerosols and on surfaces, according to a new study from National Institutes of Health, CDC, UCLA and Princeton University scientists in The New England Journal of Medicine."  (ref. here). 

Per ASHRAE, "Ventilation air is the minimum amount of outdoor air required for the purpose of controlling air contaminant levels in buildings."  Increase and improve ventilation to help control disease transmission.  What's your facility outdoor ventilation air rate?
