Evidence from whole genome sequencing of aerosol transmission of SARS-CoV-2 almost 5 hours after hospital room turnover
“Airborne SARS-CoV-2 may transmit infection after more than 4 hours.”
Experimental evidence suggests that Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) remains viable within aerosols with a half-life of approximately 3 hours; however, it remains unclear how long airborne SARS-CoV-2 can transmit infection. Whole genome sequencing during an outbreak suggested in-room transmission of SARS-CoV-2 to two patients admitted nearly 2 and 5 hours, respectively, after discharge of an asymptomatic infected patient. These findings suggest that airborne SARS-CoV-2 may transmit infection for over 4 hours, even in a hospital setting.

8 Places You’re Still Most Likely To Catch Covid

COVID-19 hitches a ride on mucus to spread deep into lungs, live imaging shows.
Investigators observed that the movement of mucus can spread the COVID-19 virus inside the respiratory tract, where it later forms aerosols that infect other people.
Comparing strategies for the mitigation of SARS-CoV-2 airborne infection risk in tiered auditorium venues
study on COVID-19 in auditoriums found displacement ventilation minimized infection risk, while natural ventilation had highest spread.
Masks, shorter events, and lower occupancy helped reduce risks.
