Currently, SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) is a major worldwide public-health problem Here, its propagation is modeled by using a probabilistic cellular automaton (PCA) In this model, sick individuals can either remain asymptomatic during the infection or become symptomatic In order to derive an analytical expression for the basic reproduction number R0, a mean-field approximation written in terms of ordinary differential equations (ODE) is proposed and analyzed By considering time-constant and time-varying parameters in both approaches (PCA and ODE), numerical simulations are performed in order to evaluate the impact of distinct quarantine regimes on the SARS-CoV-2 pandemic
