Global analyses of a state-dependent impulsive system for an SIRS model with a nonlinear incidence rate
, however, the model may exhibit bistability between the disease-free periodic solution and an endemic periodic solution, where the final outcome depends sensitively on the initial infection size, which is consistent with the weak transmissibility and controllable low-level prevalence.
