Face masks have been widely advocated to mitigate the airborne transmission of viruses including the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (e.g., Lelieveld et al., 2020). They can reduce the emission and spread of respiratory viruses through airborne droplets and aerosols as well as the inhalation of airborne viruses. The effectiveness of masks, however, …[Read More]
