Airborne Transmission of SARS-CoV-2 Theoretical Considerations and Available Evidence

The corona virus 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 coronavirus2 (SARSCoV-2),are transmitted via respiratory droplets vs aerosols. Droplets are classically described as large rentities (>5μm)that rapidly drop to the ground by force of gravity, typically within 3 to 6 feet of the source person. Aerosols are smaller particles (<5μm) that rapidly evaporate in the air,leaving behind droplet nuclei that are small enough and light enough to remain suspended in the air for hours (analogous to pollen).
