报告摘要 Abstract: 

    In this talk, we are concerned with the effects of time delay describing latent period, the variety of infectivity, mortality and recovery rates over the infection period and the waning vaccine-induced immunity on the transmission dynamics of an infectious disease. By means of Lyapunov functionals and LaSalle's invariance principle, we show that the global transmission dynamics of the disease is completely determined by the basic reproduction number.
