摘要：The dynamics of a viral infection model with nonautonomous lytic immune response is studied from the perspective of dying out of the disease. With the
help of the theory of exponential dichotomy of linear systems, we give a new proof
about the global asymptotic stability of the infection-free equilibrium for the case
𝑅0=1. The result improves and complements one of the results of Wang et al. (2006).
