A mathematical analysis of the impact of maternally derived immunity and double-dose vaccination on the spread and control of measles

open access: yesComputational and Mathematical Biophysics, 2023
Measles is a highly communicable viral infection that mostly affects children aged 5 years and below. Maternal antibodies in neonates help protect them from infectious diseases, including measles. However, maternal antibodies disappear a few months after

Optimal Control for a COVID-19 Model Accounting for Symptomatic and Asymptomatic

open access: yesComputational and Mathematical Biophysics, 2020
Building on an SEIR-type model of COVID-19 where the infecteds are further divided into symptomatic and asymptomatic, a system incorporating the various possible interventions is formulated.

Existence and uniqueness of periodic orbits in a discrete model on Wolbachia infection frequency

open access: yesAdvances in Nonlinear Analysis, 2021
In this paper, we study a discrete model on Wolbachia infection frequency. Assume that a periodic and impulsive release strategy is implemented, where infected males are released during the first N generations with the release ratio α, and the release is

Effect of saturated treatment on malaria spread with optimal intervention

open access: yesAlexandria Engineering Journal, 2023
This work presents a new deterministic model which considers transmission mode through blood transfusion and saturated treatment function with a view to gaining more insights into the dynamical spread of malaria.

Within-host models of dengue virus transmission with immune response

open access: yesComputational and Mathematical Biophysics, 2023
Dengue fever is an infectious viral fever. The complex behavior of the virus within the body can be explained through mathematical models to understand the virus’s dynamics.

Global Stability Analysis of a General Model of Zika Virus

open access: yesNonautonomous Dynamical Systems, 2019
Mathematical models of Zika virus dynamics are relatively new, and they mostly focus on either vector and horizontal, or vector and vertical transmission only.

Low temperatures or high isolation delay increases the average COVID-19 infections in India : A Mathematical modeling approach

open access: yesComputational and Mathematical Biophysics, 2021
The dynamics of COVID-19 in India are captured using a set of delay differential equations by dividing a population into five compartments. The Positivity and Boundedness of the system is shown.

Effect of Vaccination to COVID-19 Disease Progression and Herd Immunity

open access: yesComputational and Mathematical Biophysics, 2021
A mathematical model of COVID-19 with a delay-term for the vaccinated compartment is developed. It has parameters accounting for vaccine-induced immunity delay, vaccine effectiveness, vaccination rate, and vaccine-induced immunity duration.

Fractional dynamics of 2019-nCOV in Spain at different transmission rate with an idea of optimal control problem formulation

open access: yesAlexandria Engineering Journal, 2022
In this article, we studied the fractional dynamics of the most dangerous deathly disease which outbreaks have been recorded all over the world, called 2019-nCOV or COVID-19.
