Accordingly, the physical-chemical factors that control droplet evaporation and sedimentation times and play important roles in determining the infection risk from airborne respiratory droplets are reviewed in this article.doi:10.1016/j.cocis.2021.101471Majid Rezaei...
It had been assumed that we could, through the identification of a pathogen and/or procedure, accurately categorize airborne pathogens from those transmitted via droplets. For severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), the main routes of transmission are via droplets and contact ...
although the termairbornehas not been used uniformly. As defined by Wells and Riley in 1937, true airborne transmission is by infectious droplet nuclei, that is, the 1 to 5 μm dried residua of larger respiratory droplets that stop settling, buoyed by ordinary room...

The coronavirus disease 2019 (COVID-19) pandemic has reawakened the long-standing debate about the extent to which common respiratory viruses, including the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), are transmitted via respiratory droplets vs aerosols. Droplets are classically desc...
transformations in the atmosphere on a wide range of spatial and temporal scales3,8. Aerosols can contain biological particles such as bacteria and viruses9. Airborne severe acute respiratory syndrome coronavirus 2 virion-containing aerosols are significant in the coronavirus disease 2019 transmission10,...

Shifting messages and confusion about the meaning of “respiratory,”“aerosol” and “airborne” transmission hampered the early response to COVID-19. Initially, the coronavirus was thought to be transmitted only in respiratory droplets at close range, but it later became clear that it could ling...
