“…The SIR model is a highly nonlinear dynamical system, particularly so in the case of COVID-19, due to its diverse characteristics. The rates of transmission and removal in the case of the COVID-19 depend on the evolution of the epidemic disease over time, see ( Acedo, Morano, Santonja, & Villanueva, 2016 ; Liu, Wei, & Zhang, 2019 ).
