LI Dong-mei, ZHANG Yu, WANG Shu-zhong, et al. Pulse Vaccination of a SIR Epidemic Model with Saturated Incidence[J]. 2016, 21(3): 106-113.DOI: 10.15938/j.jhust.2016.03.021.
This paper studies a class of pulse vaccination of a SIR epidemic model with vertical transmission saturated incidence. We study model with the existence and stability of the disease-free periodic solution
find the conditions of global stability of the disease-free periodic solution and the uniform persistence
and carry on the numerical simulation to verify the correctness of the conclusion. At the same time
we give parameters in the model for the influence of spread the disease.
