Spatial Models and Masks in Indoor Analysis for the Spread of COVID-19

Face masks have been shown to slow or stop the spread of airborne COVID-19 droplets and aerosols. There is an apparent lack of research examining the effect of different types of masks used at the same time, and their impact on the spread of viral particles in a spatial sense. We introduce a rapid prototype model to overcome the issues in the available research using the Cell-DEVS formalism. We also build scenarios for the model to examine the effectiveness of all types of masks and respirators recommended by the World Health Organization on the spread of viral particles in an indoor environment. © 2021 IEEE.
