In the history of the world, contagious diseases have been proved to pose serious threats to
humanity that needs uttermost research in the field and its prompt implementations. With this …

In this paper, we analyze a stochastic coronavirus (COVID-19) epidemic model which is
perturbed by both white noise and telegraph noise incorporating general incidence rate …

In this work, we investigate a stochastic epidemic model with relapse and distributed delay.
First, we prove that our model possesses and unique global positive solution. Next, by …

The aim of this work is to study a new stochastic SIRS epidemic model that includes the
mean-reverting Ornstein–Uhlenbeck process and a general incidence rate. First, we prove …

In this paper, a delayed SIQR epidemic model with vaccination and elimination hybrid
strategies is analysed under a white noise perturbation. We prove the existence and the …

Threshold dynamics of a stochastic SIHR epidemic model of COVID-19 with general
population-size dependent contact rate Page 1 http://www.aimspress.com/journal/mbe MBE, 19(4) …

Epidemic models have long been used to study information diffusion in complex artificial,
biological and social networks. Here, we propose a novel recurrent-state epidemic model for …

The aim of this paper is to investigate a stochastic threshold for a delayed epidemic model
driven by Lévy noise with a nonlinear incidence and vaccination. Mainly, we derive a …

In this paper, we propose a novel stochastic SEIQ model of a disease with the general
incidence rate and temporary immunity. We first investigate the existence and uniqueness of …

A stochastic SIRS epidemic model with generalized nonlinear incidence and Lévy noise is
investigated. First, we show the existence and uniqueness of a global positive solution …
