Persistence of Severe Acute Respiratory Syndrome Coronavirus 2 in Aerosol Suspensions

We aerosolized severe acute respiratory syndrome coronavirus 2 and determined that its dynamic aerosol efficiency surpassed those of severe acute respiratory syndrome and Middle East respiratory syndrome coronaviruses. Although we performed experiments only once in each of several laboratories, our findings suggest retained infectivity and virion integrity for up to 16 hours in respirable-sized aerosols.
