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 …

A SIR model assumption for the spread of COVID-19 in different communities
I Cooper, A Mondal, CG Antonopoulos - Chaos, Solitons & Fractals, 2020 - Elsevier
In this paper, we study the effectiveness of the modelling approach on the pandemic due to
the spreading of the novel COVID-19 disease and develop a susceptible-infected-removed …

Predicting the evolution of the COVID-19 epidemic with the A-SIR model: Lombardy, Italy and Sao Paulo state, Brazil
AGM Neves, G Guerrero - Physica D: Nonlinear Phenomena, 2020 - Elsevier
The presence of a large number of infected individuals with few or no symptoms is an
important epidemiological difficulty and the main mathematical feature of COVID-19. The A …

Non-Markovian SIR epidemic spreading model of COVID-19
We introduce non-Markovian SIR epidemic spreading model inspired by the characteristics
of the COVID-19, by considering discrete-and continuous-time versions. The distributions of …

A simple but complex enough θ-SIR type model to be used with COVID-19 real data. Application to the case of Italy
Since the start of the COVID-19 pandemic in China many models have appeared in the
literature, trying to simulate its dynamics. Focusing on modeling the biological and …

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 …

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 …

Basing on existence of the mathematically sequential reduction of the three-compartmental
(Susceptible-Infected-Recovered/Removed) model to the Verhulst (logistic) equation with …

A SIDARTHE model of COVID-19 epidemic in Italy
In late December 2019, a novel strand of Coronavirus (SARS-CoV-2) causing a severe,
potentially fatal respiratory syndrome (COVID-19) was identified in Wuhan, Hubei Province …
