A time-varying SIRD model for the COVID-19 contagion in Italy
The purpose of this work is to give a contribution to the understanding of the COVID-19
contagion in Italy. To this end, we developed a modified Susceptible-Infected-Recovered …

A simple SIR model with a large set of asymptomatic infectives
G Gaeta - arXiv preprint arXiv:2003.08720, 2020 - arxiv.org
There is increasing evidence that one of the most difficult problems in trying to control the
ongoing COVID-19 epidemic is the presence of a large cohort of asymptomatic infectives …

A SIR-type model describing the successive waves of COVID-19
GA Muñoz-Fernández, JM Seoane… - Chaos, Solitons & …, 2021 - Elsevier
It is well-known that the classical SIR model is unable to make accurate predictions on the
course of illnesses such as COVID-19. In this paper, we show that the official data released …

Size and timescale of epidemics in the SIR framework
The most important features to assess the severity of an epidemic are its size and its
timescale. We discuss these features in a systematic way in the context of SIR and SIR-type …
