Epidemic Analysis and Mathematical Modelling of H1N1 (A) with Vaccination

open access: yesNonautonomous Dynamical Systems, 2022
This article investigates a proposed new mathematical model that considers the infected individuals using various rate coefficients such as transmission, progression, recovery, and vaccination.

A Dynamic SIqIRV Mathematical model with Non-linear Force of Isolation, Infection and Cure

open access: yesNonautonomous Dynamical Systems, 2022
The Susceptible-Isolated-Infected-Recovered-Vaccinated (SIqIRV) deterministic model is examined in this paper. This model considers a nonlinear force of quarantine, infection and care, where vaccinated individuals lose their immunity after a period of ...

Complex dynamics of a four-species food-web model: An analysis through Beddington-DeAngelis functional response in the presence of additional food

open access: yesComputational and Mathematical Biophysics, 2023
The four-dimensional food-web system consisting of two prey species for a generalist middle predator and a top predator is proposed and investigated. The middle predator is predating over both the prey species with a modified Holling type-II functional ...

A Study of Within-Host Dynamics of Dengue Infection incorporating both Humoral and Cellular Response with a Time Delay for Production of Antibodies

open access: yesComputational and Mathematical Biophysics, 2021
a. Background: Dengue is an acute illness caused by a virus. The complex behaviour of the virus in human body can be captured using mathematical models. These models helps us to enhance our understanding on the dynamics of the virus.

Dynamics of two-species delayed competitive stage-structured model described by differential-difference equations

open access: yesOpen Mathematics, 2019
Overf the last few years, by utilizing Mawhin’s continuation theorem of coincidence degree theory and Lyapunov functional, many scholars have been concerned with the global asymptotical stability of positive periodic solutions for the non-linear ...

Mathematical analysis of an epidemic model with direct and indirect transmission modes and two delays

open access: yesNonautonomous Dynamical Systems, 2023
In this article, we consider an epidemiological model in which we take into account the effects of direct and indirect transmissions. The first mode occurs through direct contact between infectious and susceptible individuals, and the second one will ...

Optimal strategies for controlling the outbreak of COVID-19: Reducing its cost and duration

open access: yesNonautonomous Dynamical Systems, 2023
Social distancing plays an essential role in controlling the spread of an epidemic, but changing the behavior of individuals regarding social distancing is costly.

Dynamics of an eco-epidemic model with Allee effect in prey and disease in predator

open access: yesComputational and Mathematical Biophysics, 2023
In this work, the dynamics of a food chain model with disease in the predator and the Allee effect in the prey have been investigated. The model also incorporates a Holling type-III functional response, accounting for both disease transmission and ...

Modelling the Effects of Condom Use and Antiretroviral Therapy in Controlling HIV/AIDS among Heterosexuals, Homosexuals and Bisexuals

open access: yesComputational and Mathematical Methods in Medicine, Volume 11, Issue 3, Page 201-222, 2010., 2010
A deterministic compartmental sex‐structured HIV/AIDS model for assessing the effects of homosexuals and bisexuals in heterosexual settings in which homosexuality and bisexuality issues have remained taboo is presented. We extend the model to focus on the effects of condom use as a single strategy approach in HIV prevention in the absence of any other ...

Optimal Control of Vertically Transmitted Disease: An Integrated Approach

open access: yesComputational and Mathematical Methods in Medicine, Volume 11, Issue 4, Page 369-387, 2010., 2010
We study the dynamics of a disease under administration of a vaccine and antiviral drug, where the disease transmits directly from the parents to the offspring (vertical transmission) and also through contact with infective individuals (horizontal transmission).
