Poor ventilation worsens short‐range airborne transmission of respiratory infection
Poor ventilation worsens short‐range airborne transmission of respiratory infection
To explain the observed phenomenon that most SARS-CoV-2 transmission occurs indoors whereas its outdoor transmission is rare, a simple macroscopic aerosol balance model is developed to link short- and long-range airborne transmission. The model considers the involvement of exhaled droplets with initial diameter ≤50 µm in the short-range airborne route, …
