Dynamics of COVID-19 epidemics: SEIR models underestimate peak infection rates and overestimate epidemic duration [PDF]
, 2020 Compartment models of infectious diseases, such as SEIR, are being used extensively to model the COVID-19 epidemic. Transitions between compartments are modelled either as instantaneous rates in differential equations, or as transition probabilities in ...

Supply Chain Risk Diffusion in Partially Mapping Double-Layer Hypernetworks
Entropy, 2023 The impact of COVID-19 is global, and uncertain information will affect product quality and worker efficiency in the complex supply chain network, thus bringing risks.

A process of rumour scotching on finite populations [PDF]
Royal Society Open Science, 2015 Rumour spreading is a ubiquitous phenomenon in social and technological networks. Traditional models consider that the rumour is propagated by pairwise interactions between spreaders and ignorants.

Role of word-of-mouth for programs of voluntary vaccination: A game-theoretic approach [PDF]
, 2015 We propose a model describing the synergetic feedback between word-of-mouth (WoM) and epidemic dynamics controlled by voluntary vaccination. We combine a game-theoretic model for the spread of WoM and a compartmental model describing $SIR$ disease ...

Modeling Vaccine Efficacy for COVID-19 Outbreak in New York City
Biology, 2022 In this article we study the efficacy of vaccination in epidemiological reconstructions of COVID-19 epidemics from reported cases data. Given an epidemiological model, we developed in previous studies a method that allowed the computation of an ...

The SIS epidemic model with Markovian switching [PDF]
, 2012 Population systems are often subject to environmental noise. Motivated by Takeuchi et al. (2006), we will discuss in this paper the effect of telegraph noise on the well-known SIS epidemic model.

Mathematical Biosciences and Engineering, 2010 The mathematical theory of single outbreak epidemic models really began with the work of Kermack and Mackendrick about decades ago. This gave a simple answer to the long-standing question of why epidemics woould appear suddenly and then disappear just as suddenly without having infected an entire population.

Fractional SIS Epidemic Models [PDF]
Fractal and Fractional, 2020 In this paper, we consider the fractional SIS (susceptible-infectious-susceptible) epidemic model (α-SIS model) in the case of constant population size. We provide a representation of the explicit solution to the fractional model and we illustrate the results by numerical schemes.

State space collapse for critical multistage epidemics [PDF]
, 2014 We study a multistage epidemic model which generalizes the SIR model and where infected individuals go through K>0 stages of the epidemic before being removed.
