H7N9 Avian Influenza Model with Different Groups to Distinguish Between High and Low Risk Groups
In order to study the transmission process of H7N9,taking into account the different transmission rates of poultry in farms and poultry in vegetable markets to humans,an H7N9 avian influenza model with different groups of high and low risk groups was estab-lished.Through dynamic analysis,the basics of the model were obtained.The existence of the regeneration number and the equilibrium point,and the Jacobian matrix and Lyapunov function are used to give the stability conditions of the system equilibrium point.Finally,the theoretical results are verified by numerical simulation and effective measures to prevent avian influenza are given.
