In this paper, we analyzed a stochastic rabies epidemic model perturbed by white noise and telegraph noise. We proved the existence of a unique global positive solution, established a sufficient condition for the existence of a unique ergodic stationary distribution of positive solutions, and discussed sufficient conditions for disease extinction. Numerical simulations were used to illustrate the theoretical results.
In this paper, we analyze a stochastic rabies epidemic model which is perturbed by both white noise and telegraph noise. First, we prove the existence of the unique global positive solution. Second, by constructing an appropriate Lyapunov function, we establish a sufficient condition for the existence of a unique ergodic stationary distribution of the positive solutions to the model. Then we establish sufficient conditions for the extinction of diseases. Finally, numerical simulations are introduced to illustrate our theoretical results.
