چکیده
|
To be more precise about the real world activity,a stochastic multigroup seir epidemic model is formulated. we define the basic reproduction number r0s and show that it is a sharp threshold for the dynamics of sde model. if r0s < 1,the disease-free equilibrium is asymptotically stable; and if r0s > 1,the disease persists and there exists a globally asymptotically stable stationary distribution. numerical simulation examples are carried out to substantiate the analytical results. © 2014 xiaojing zhong and feiqi deng.
