Networks and epidemic models [PDF]

open access: yesJournal of The Royal Society Interface, 2005
Networks and the epidemiology of directly transmitted infectious diseases are fundamentally linked. The foundations of epidemiology and early epidemiological models were based on population wide random-mixing, but in practice each individual has a finite set of contacts to whom they can pass infection; the ensemble of all such contacts forms a ‘mixing ...

Evaluating the Dynamics of Bluetooth Low Energy Based COVID-19 Risk Estimation for Educational Institutes

open access: yesSensors, 2021
COVID-19 tracing applications have been launched in several countries to track and control the spread of viruses. Such applications utilize Bluetooth Low Energy (BLE) transmissions, which are short range and can be used to determine infected and ...

Accuracy of models for the 2001 foot-and-mouth epidemic [PDF]

open access: yes, 2008
Since 2001 models of the spread of foot-and-mouth disease, supported by the data from the UK epidemic, have been expounded as some of the best examples of problem-driven epidemic models.

On a Discrete Epidemic Model [PDF]

open access: yesDiscrete Dynamics in Nature and Society, 2007
We investigate the global asymptotic behavior of solutions of the difference equationxn+1=(1−∑j=0k−1xn−j)(1−e−Axn),n∈ℕ0, whereA∈(0,∞),k∈{2,3,…}, and the initial valuesx−k+1,x−k+2,…,x0are arbitrary negative numbers. Asymptotics of some positive solutions of the equation are also found.

Extinction and recurrence of multi-group SEIR epidemic [PDF]

open access: yes, 2013
In this paper, we consider a class of multi-group SEIR epidemic models with stochastic perturbations. By the method of stochastic Lyapunov functions, we study their asymptotic behavior in terms of the intensity of the stochastic perturbations and the ...

A Mathematical Model to Control the Prevalence of a Directly and Indirectly Transmitted Disease

open access: yesMathematics, 2021
In this paper, a mathematical model to describe the spread of an infectious disease on a farm is developed. To analyze the evolution of the infection, the direct transmission from infected individuals and the indirect transmission from the bacteria ...

Performance Modeling of Epidemic Routing [PDF]

open access: yesComputer Networks, 2006
In this paper, we develop a rigorous, unified framework based on ordinary differential equations (ODEs) to study epidemic routing and its variations. These ODEs can be derived as limits of Markovian models under a natural scaling as the number of nodes increases.

Modeling the effect of quarantine and vaccination on Ebola disease

open access: yesAdvances in Difference Equations, 2017
Ebola virus infection is a severe infectious disease with the highest case fatality rate which has become the global public health treat now. What makes the disease the worst of all is no specific effective treatment available, its dynamics is not much ...

The Effects of Behavioral Restrictions on the Spread of COVID-19

open access: yesReports, 2022
Several measures, including behavioral restrictions for individuals, have been taken throughout the world to control the spread of COVID-19. The aim of these measures is to prevent infected persons from coming into contact with susceptible persons. Since
