| Abstract: | According to the principle of epidemic dynamics, we established a class of SIRS epidemic model based on psychology effect. The sufficient conditions for the global asymptotic stability of the model at the disease free equilibrium point and endemic disease equilibrium point were obtained by constructing Lyapunov function, using the stability of ordinary differential equation and the theory of limit system, and then the results
were verified by numerical simulation. The results of numerical simulation show that the positive influence of psychology effects can control the spread and prevalence of infectious diseases to a certain extent. |
