吴琼, 滕志东. 一类具有饱和发生率和治疗的SIS传染病模型的后向分支及动力学行为[J]. Journal of Xinjiang University (Natural Science Edition in Chinese and English), 2014, 31(2): 174-180.DOI:
backward bifurcation and dynamical behaviors of an SIS epidemic model with saturated incidence rate and treatment is investigated.It is assumed that treatment rate is proportional to the number of infectives below the capacity and is a constant when the number of infectives is greater than the capacity.It is found that a backward bifurcation occurs if the capacity is small.Theoretical and numerical results suggest that decreasing the basic reproduction number below one only is insufficient for disease eradication.
