Aerosol transmission of SARS-CoV-2: Physical principles and implications. Update on ventilation (October 31, 2020) — Supporting UV 222 nm Irradiation

See t.ly/pVRt — Since the possibility of aerosol transmission of the SARS-CoV-2 virus was recognisedit has become clear that increasing the amount of ventilation is helpful, and this general realisation has been quite widely incorporated into policy. But there is much more to it than the amount of ventilation. Current understanding of how virus-containing aerosols accumulate and move inindoor spaces should make it possible to identify buildings or rooms where the riskis particularly high and take action to limit their use or improve their ventilation. Ina much wider range of buildings, relatively simple changes to the operation ofmechanical ventilation…
