In this paper, we have proposed a nonlinear mathematical model of different classes of individuals for coronavirus (COVID-19) The model incorporates the effect of transmission and treatment on the occurrence of new infections For the model, the basic reproduction number (R0) has been computed Corresponding to the threshold quantity (R0), the stability of endemic and disease-free equilibrium (DFE) points are determined For 0 &gt; 1, if the endemic equilibrium point exists, then it is locally asymptotically stable, whereas the DFE point is globally asymptotically stable for R0 &lt; 1 which implies the eradication of the disease The effects of various parameters on the spread of COVID-19 are discussed in the segment of sensitivity analysis The model is numerically simulated to understand the effect of reproduction number on the transmission dynamics of the disease COVID-19 From the numerical simulations, it is concluded that if the reproduction number for the coronavirus disease is reduced below unity by decreasing the transmission rate and detecting more number of infectives, then the epidemic can be eradicated from the population © 2021 World Scientific Publishing Company
