Backward bifurcation, basic reinfection number and robustness of a SEIRE epidemic model with reinfection
Shaoli Wang, Tengfei Wang, Ya-nen Qi +1
Recent evidences show that individuals who recovered from COVID-19 can be reinfected. However, this phenomenon has rarely been studied using mathematical models. In this paper, we…
Backward bifurcation and saddle-node bifurcation in virus-immune dynamics
Tengfei Wang, Shaoli Wang, Fei Xu
Recently, Wang and Xu [ Appl. Math. Lett. 78 (2018) 105-111] studied thresholds and bi-stability in virus-immune dynamics. In this paper, we show there also exist backward bifurcat…
Psychological effect can lead to bistability in epidemics
Shaoli Wang, Xiyan Bai
In this paper, we study the psychological effect in a SIS epidemic model. The basic reproduction number is obtained. However, the disease free equilibrium is always asymptotically…
Bistability in a SIRS model with general nonmonotone and saturated incidence rate
Shaoli Wang, Xiyan Bai, Fei Xu
In this paper, we consider a SIRS model with general nonmonotone and saturated incidence rate and perform stability and bifurcation analysis. We show that the system has saddle-nod…
Monotonic and nonmonotonic immune responses in viral infection systems
Shaoli Wang, Huixia Li, Fei Xu
In this paper, we study two-dimensional, three-dimensional monotonic and nonmonotonic immune responses in viral infection systems. Our results show that the viral infection systems…
Thresholds and bistability in HIV infection models with oxidative stress
Shaoli Wang, Fei Xu, Xinyu Song
Oxidative stress, a reaction caused by the imbalance between the reactive oxygen species of human organism and its ability to detoxify reactive intermediates and to repair the resu…
