A vaccination model for COVID-19 in Gauteng, South Africa

open access: yesInfectious Disease Modelling, 2022
The COVID-19 pandemic provides an opportunity to explore the impact of government mandates on movement restrictions and non-pharmaceutical interventions on a novel infection, and we investigate these strategies in early-stage outbreak dynamics.

Estimating the reproduction number and designing the integrated strategies against dengue

open access: yesResults in Physics, 2021
Dengue poses social and economic burden in the world. Around 390 million cases have been identified with 96 millions showing clinical symptoms. Vector control methods have been widely used as strategies against dengue.

An optimal control approach to malaria prevention via insecticide-treated nets [PDF]

open access: yes, 2013
Malaria is a life threatening disease, entirely preventable and treatable, provided the currently recommended interventions are properly implemented. These interventions include vector control through the use of insecticide-treated nets (ITNs).

A primer on stochastic epidemic models: Formulation, numerical simulation, and analysis

open access: yesInfectious Disease Modelling, 2017
Some mathematical methods for formulation and numerical simulation of stochastic epidemic models are presented. Specifically, models are formulated for continuous-time Markov chains and stochastic differential equations. Some well-known examples are used

Lyapunov Functions for Tuberculosis Models with Fast and Slow Progression [PDF]

open access: yes, 2006
The spread of tuberculosis is studied through two models which include fast and slow progression to the infected class. For each model, Lyapunov functions are used to show that when the basic reproduction number is less than or equal to one, the disease ...

Cluster formation for multi-strain infections with cross-immunity [PDF]

open access: yes, 2005
Many infectious diseases exist in several pathogenic variants, or strains, which interact via cross-immunity. It is observed that strains tend to self-organise into groups, or clusters.

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.

The multistep Laplace optimized decomposition method for solving fractional-order coronavirus disease model (COVID-19) via the Caputo fractional approach

open access: yesDemonstratio Mathematica, 2022
COVID-19, a novel coronavirus disease, is still causing concern all over the world. Recently, researchers have been concentrating their efforts on understanding the complex dynamics of this widespread illness.

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
