Dynamic Behavior of a Random SEIR Epidemic Model with Nonlinear Birth Rate and Saturation Recovery Rate
A stochastic SEIR infectious disease model with nonlinear birth rate and nonlinear contact rate is stud-ied,including the extinction,persistence,and stationary distribution problems. Moreover,the obtained conclu-sions are verified through computer numerical simulation. The results obtained in this article improve the conclu-sions of relevant literature.
