Abstract:The Ebola virus is a virus with the ability to cross species.Due to its high fatality rate,it is of great significance to study its transmission process.By considering three different transmission modes of the Ebola virus,a SEIRDP model is established.The basic reproduction number of the model is obtained by using the nextgeneration matrix,and the equilibrium points and their local stability "are obtained.Then,the global asymptotic stability of the equilibrium points of the model is obtained by using the Lyapunov function method.Finally,numerical simulations of the model are carried out to verify the correctness of the theoretical conclusions.
