一类受疾病意识和疫苗接种影响的时滞传染病模型
A Delayed Epidemic Model Affected by Disease Awareness and Vaccination
摘要
Abstract
In this paper,a delayed epidemic model affected by disease awareness and vaccination is estab-lished.The basic regeneration number of the model is given,and the stability of the disease-free equilib-rium point and the endemic equilibrium point of the model is analyzed.Then,the discriminant condition that generates Hopf bifurcation is provided,and the effects of disease awareness conversion rate and vac-cination rate on infected population are studied.The results show that when the delay is the branch pa-rameter,the equilibrium point may have periodic solutions through the Hopf bifurcation.关键词
