摘 要：In this work,we propose and investigate an ordinary differential equations model describing the spread of COVID-19 in *** model takes into account the asymptomatic,unreported symptomatic,quarantine,hospitalized individuals and the amount of virus in the environment,for evaluating their impact on the transmission of the *** establishing the basic properties of the model,we compute the control reproduction number Rc and show that the disease dies out whenever Rc1 and is endemic whenever Rc***,an optimal control problem is derived and investigated theoretically by mainly relying on Pontryagin s maximum *** illustrate the theoretical analysis by presenting some graphical results.
