In many cases, the distant collective transmission of Coronavirus Disease (COVID-19) primarily occurs through aerosolized respiratory particles. To elucidate the spatial dispersion of SARS-CoV-2-virions under indoor ventilation conditions, this study utilized Lagrangian particle tracking Computational Fluid Dynamics (CFD) simulations to analyse aerosols emitted from an infected host within a single room (dimensions: width x depth x height = 5 x 5 x 4 m) at three distinct levels of population density. The spatial risks of collective COVID-19 infection were accessed and compared across 13 distinct air-circulation settings. Our findings demonstrate that a mixed circulation combining a standing air purifier and ceiling outlets significantly outperforms other strategies in reducing the airborne infection. Conversely, ceiling-mounted air conditioning and natural ventilation methods are found to be less effective.
