Bayesian Inference for SIR Epidemic Model with dependent parameters

open access: yesMoroccan Journal of Pure and Applied Analysis, 2022
This paper is concerned with the Bayesian inference for the dependent parameters of stochastic SIR epidemic model in a closed population. The estimation framework involves the introduction of m − 1 latent data between every pair of observations. Kibble’s

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 Efficient Numerical Study of Measles Transmission Dynamics With Time Delay

open access: yesJournal of Mathematics, Volume 2026, Issue 1, 2026.
Measles is a highly contagious viral disease that remains a public‐health concern in populations with suboptimal vaccination coverage. In this study, a delayed SEIR‐type epidemic model is formulated to investigate measles transmission dynamics, where the latent period is incorporated through a discrete time delay.

Are the upper bounds for new SARS-CoV-2 infections in Germany useful?

open access: yesComputational and Mathematical Biophysics, 2021
At the end of 2019, an outbreak of a new coronavirus, called SARS–CoV–2, was reported in China and later in other parts of the world. First infection reported in Germany by the end of January 2020 and on March 16th, 2020 the federal government announced ...

Determination in Galicia of the required beds at Intensive Care Units

open access: yesAlexandria Engineering Journal, 2021
By using a recent mathematical compartmental model that includes the super-spreader class and developed by Ndaïrou, Area, Nieto, and Torres, a procedure to estimate in advance the number of required beds at intensive care units is presented.

Fractional Adomian J‐Transform Method for Time‐Fractional Diffusion‐Wave Equations: Theory and Applications

open access: yesJournal of Mathematics, Volume 2026, Issue 1, 2026.
In this research, we introduce the fractional Adomian J‐transform method FAJM, which functions as a robust hybrid analytical‐numerical framework. Diverging from traditional transform techniques, the FAJM leverages the specific scaling attributes of the J‐transform to streamline the inversion of nonlocal fractional operators.

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

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.

The effect of changing COVID-19 restrictions on the transmission rate in a veterinary clinic

open access: yesInfectious Disease Modelling, 2023
With the declaration of the COVID-19 pandemic by the World Health Organization on March 11, 2020, the University of Tennessee College of Veterinary Medicine (UTCVM), like other institutions, restructured their services to reduce the potential spread of ...

On a stochastic epidemic SIR model with non-homogeneous population: a toy model for HIV

open access: yesOpen Mathematics
In this paper, we generalise a simple discrete-time stochastic SIR-type model introduced by Tuckwell and Williams. The SIR model by Tuckwell and Williams assumes a homogeneous population, a fixed infectious period, and a strict transition from ...
