چکیده
Based on the spread of COVID-19, in present paper, an imperfectly vaccinated SVEIR model for latent age is proposed. At first, equilibrium points and basic reproduction number are calculated. Then, we discuss asymptotic smoothness uniform persistence semiflow generated by solutions system existence attractor. Moreover, LaSalle’s invariance principle Volterra type Lyapunov functions used to prove global stability both disease-free endemic model. The conclusion that if Rρ less than one, disease will gradually disappear. However, greater become persist. In addition, numerical simulations also carried out verify result. Finally, suggestions made measures control ongoing transmission COVID-19.

An sveir model for assessing potential impact of an imperfect anti-sars vaccine.
The control of severe acute respiratory syndrome (SARS), a fatal contagious viral disease that spread to over 32 countries in 2003, was based on quarantine of latently infected individuals and isolation of individuals with clinical symptoms of SARS. Owing to the recent ongoing clinical trials of some candidate anti-SARS vaccines, this study aims to assess, via mathematical modelling, the potent...
متن کاملAnalysis of an SVEIR model with age-dependence vaccination, latency and relapse
In this paper, we propose an epidemic model with age-dependence vaccination, latency and relapse. We derive the positivity and boundedness of solutions and find the basic reproduction number. Asymptotic smoothness, the existence of global compact attractor and uniform persistence of the model are investigated. By constructing Lyapunov functionals, we establish global stability of the equilibria...
متن کاملDynamical behavior of a stage structured prey-predator model
In this paper, a new stage structured prey-predator model with linear functional response is proposed and studied. The stages for prey have been considered. The proposed mathematical model consists of three nonlinear ordinary differential equations to describe the interaction among juvenile prey, adult prey and predator populations. The model is analyzed by using linear stability analysis to ob...
متن کاملA structured avian influenza model with imperfect vaccination and vaccine-induced asymptomatic infection.
We introduce a model of avian influenza in domestic birds with imperfect vaccination and age-since-vaccination structure. The model has four components: susceptible birds, vaccinated birds (stratified by vaccination age), asymptomatically infected birds, and infected birds. The model includes reduction in the probability of infection, decreasing severity of disease of vaccinated birds and vacci...
متن کاملDynamics of an Age-structured Metapopulation Model
We introduce a metapopulation model that includes both landscape changes (patch destruction and recreation) and age-dependent metapopulation dynamics. A threshold quantity is derived and related to the existence of an ecologically nontrivial equilibrium, to the stability of the speciesfree equilibrium, and to weak and strong persistence of the species. We provide examples to illustrate how age-...
