Global Stability of an SIR Epidemic Model with Delay and General Nonlinear Incidence [PDF]

open access: yes, 2010
An SIR model with distributed delay and a general incidence function is studied. Conditions are given under which the system exhibits threshold behaviour: the disease-free equilibrium is globally asymptotically stable if R0 \u3c 1 and globally attracting

Optimal Control for a Tuberculosis Model with Exogenous Reinfection under the Influence of Stigma

open access: yesComputational and Mathematical Biophysics, 2022
Often described as the world’s most deadly infectious disease, Tuberculosis remains a serious health threat in many parts of the world, especially in the developing countries.

Age Structured Mathematical Modeling Studies on COVID-19 with respect to Combined Vaccination and Medical Treatment Strategies

open access: yesComputational and Mathematical Biophysics, 2022
In this study, we develop a mathematical model incorporating age-specific transmission dynamics of COVID-19 to evaluate the role of vaccination and treatment strategies in reducing the size of COVID-19 burden.

How to Obtain Long Term Projections for Smoking Behaviour: A Case Study in the Dutch Population

open access: yesComputational and Mathematical Methods in Medicine, Volume 10, Issue 2, Page 155-164, 2009., 2009
A state‐transition model is presented to project the prevalence rates of never, current and former smokers within the Dutch population. Changes are determined by the transition rates among these three classes: start rates, quit rates and relapse rates. Both the initial prevalence rates and transition rates are calculated from cross‐sectional data using

The Dynamics of an HIV/AIDS Model with Screened Disease Carriers

open access: yesComputational and Mathematical Methods in Medicine, Volume 10, Issue 4, Page 287-305, 2009., 2009
The presence of carriers usually complicates the dynamics and prevention of a disease. They are not recognized as disease cases themselves unless they are screened and they usually spread the infection without them being aware. We argue that this has been one of the major causes of the spread of human immunodeficiency virus (HIV).

Optimal control of a fractional order epidemic model with application to human respiratory syncytial virus infection [PDF]

open access: yes, 2018
A human respiratory syncytial virus surveillance system was implemented in Florida in 1999, to support clinical decision-making for prophylaxis of premature newborns. Recently, a local periodic SEIRS mathematical model was proposed in [Stat. Optim.

Analysis of an age‐dependent SI epidemic model with disease‐induced mortality and proportionate mixing assumption: the case of vertically transmitted diseases

open access: yesJournal of Applied Mathematics, Volume 2004, Issue 3, Page 235-254, 2004., 2004
An SI epidemic model for a vertically as well as horizontally transmitted disease is investigated when the fertility, natural mortality, and disease‐induced mortality rates depend on age and the force of infection corresponds to a special form of intercohort transmission called proportionate mixing.

Evaluating early pandemic response through length-of-stay analysis of case logs and epidemiological modeling: A case study of Singapore in early 2020

open access: yesComputational and Mathematical Biophysics, 2023
It is now known that early government interventions in pandemic management helps in slowing down the pandemic in the initial phase, during which a conservative basic reproduction number can be maintained.

Vaccination in a model of an epidemic

open access: yesInternational Journal of Mathematics and Mathematical Sciences, Volume 23, Issue 6, Page 425-429, 2000., 2000
Vaccination has been included in a model which describes an epidemic. A traveling wave solution together with an equilibrium and stability analysis have been done to the model.

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
