This paper aims to study a discrete-time COVID-19 epidemic model with a saturated incidence rate. The basic reproductive number is calculated and the endemic steady state is obtained for the model. The stability of the COVID-19-free steady state (CFSS) of the model is investigated when the basic reproduction number is less than one and the step size h satisfies the exact condition. The theoretical result is also supported with numerical simulations.
