Stability Analysis of an SEIR Epidemic Model with Stochastic Perturbation and Numerical Simulation

International Journal of Nonlinear Sciences and Numerical Simulation, 2013
Abstract An SEIR epidemic model with constant immigration and random fluctuation around the endemic equilibrium is considered. As a special case, a deterministic system discussed by Li et al. will be incorporated into the stochastic version given by us.

Dynamic analysis of deterministic and stochastic SEIR models incorporating the Ornstein-Uhlenbeck process.

Chaos: An Interdisciplinary Journal of Nonlinear Science
In this paper, we introduce a Susceptible-Exposed-Infected-Recovered (SEIR) epidemic model and analyze it in both deterministic and stochastic contexts, incorporating the Ornstein-Uhlenbeck process. The model incorporates a nonlinear incidence rate and a

Dynamics of an SEIR epidemic model with saturated incidence rate including stochastic influence

2023
Summary: This paper aims to develop a stochastic perturbation into SEIR (susceptible-exposed-infected-removed) epidemic model including a saturated estimated incidence. A set of stochastic differential equations is used to study its behavior, with the assumption that each population's exposure to environmental unpredictability is represented by noise ...

Maximum likelihood estimation for a stochastic SEIR system with a COVID-19 application

International Journal of Computational Mathematics, 2022
In this paper, we propose a stochastic model for epidemiology data. The proposed model is obtained as a random perturbation of a suitable parameter in a deterministic SEIR system.
