A transmission dynamics model of COVID-19: Case of Cameroon [PDF]

open access: yesInfectious Disease Modelling, 2022
In this work, we propose and investigate an ordinary differential equations model describing the spread of COVID-19 in Cameroon. The model takes into account the asymptomatic, unreported symptomatic, quarantine, hospitalized individuals and the amount of

Global stability of a delayed SARS-CoV-2 reactivation model with logistic growth, antibody immunity and general incidence rate [PDF]

open access: yesAlexandria Engineering Journal, 2022
Mathematical models have been considered as a robust tool to support biological and medical studies of the coronavirus disease 2019 (COVID-19). This new disease is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Optimal Control of a Dengue-Dengvaxia Model: Comparison Between Vaccination and Vector Control

open access: yesComputational and Mathematical Biophysics, 2021
Dengue is the most common mosquito-borne viral infection transmitted disease. It is due to the four types of viruses (DENV-1, DENV-2, DENV-3, DENV-4), which transmit through the bite of infected Aedes aegypti and Aedes albopictus female mosquitoes during

Stability analysis of an SIR model with alert class modified saturated incidence rate and Holling functional type-II treatment

open access: yesComputational and Mathematical Biophysics, 2023
This study discusses an SIR epidemic model with modified saturated incidence rates and Holling functional type-II therapy. In this study, we take the new alert compartment (A) in the SIR compartment model.

On the Dynamics of Sexually Transmitted Diseases Under Awareness and Treatment

open access: yesFrontiers in Applied Mathematics and Statistics, 2022
In this paper, we develop and extend the work of Jia and Qin on sexually transmitted disease models with a novel class of non-linear incidence. Awareness plays a central role both in the susceptible and the infectious classes.

A temperature-dependent mathematical model of malaria transmission with stage-structured mosquito population dynamics

open access: yesNonautonomous Dynamical Systems, 2021
In this paper, we formulate a temperature-dependent model for malaria transmission dynamics which includes immature stages of mosquitoes. The model is constructed by using ordinary differential equations with some parameters which are periodic functions.

Global stability dynamics and sensitivity assessment of COVID-19 with timely-delayed diagnosis in Ghana

open access: yesComputational and Mathematical Biophysics, 2022
In this paper, we study the dynamical effects of timely and delayed diagnosis on the spread of COVID-19 in Ghana during its initial phase by using reported data from March 12 to June 19, 2020. The estimated basic reproduction number, ℛ0, for the proposed

Mathematical analysis of a MERS-Cov coronavirus model

open access: yesDemonstratio Mathematica, 2022
In this study, we have proposed a mathematical model to describe the dynamics of the spread of Middle East Respiratory Syndrome disease. The model consists of six-coupled ordinary differential equations.

Metapopulation Dynamics with Migration and Local Competition [PDF]

open access: yes, 2002
MSC2000: primary 34D15, 34D23, 92B05; secondary 34K60, 34E13, 92D40.Many patch-based metapopulation models assume that the local population within each patch is at its equilibrium and independent of changes in patch occupancy.

A mathematical model to study the spread of COVID-19 and its control in India

open access: yesComputational and Mathematical Biophysics, 2023
In this article, a nonlinear mathematical model is proposed and analyzed to study the spread of coronavirus disease (COVID-19) and its control. Due to sudden emergence of a peculiar kind of infection, no vaccines were available, and therefore, the ...
