报告摘要
Vector-borne infectious diseases may involve horizontal transmission between hosts in addition to transmission from infected vectors to susceptible hosts. In this talk, we develop a vector-borne disease model with general nonlinear incidence rates and continuous age structures in both infectious hosts and vectors. We first study the existence and local stability of steady states, which is completely determined by the basic reproduction number. With the assistance of the existence of a global attractor and the uniform persistence, a threshold dynamics is established by employing the Fluctuation Lemma and the approach of Lyapunov functionals.
