Abstract:

In this paper, the local stability of the endemic equilibrium and existence of a Hopf bifurcation in a Susceptible-ExposedInfected-Recovered (SEIR) delayed mathematical model for COVID-19 pandemic are investigated. By using time-delay as a bifurcationparameter, the associated characteristic equation is analyzed to reveal dynamics of the model. Finally, numerical simulations areperformed with suitable parameters choice to illustrate the theoretical results of the model.
