A new compartmental epidemiological model for COVID-19 with a case study of Portugal
AP Lemos-Paiao, CJ Silva, DFM Torres - Ecological Complexity, 2020 - Elsevier
We propose a compartmental mathematical model for the spread of the COVID-19 disease,
showing its usefulness with respect to the pandemic in Portugal, from the first recorded case
in the country till the end of the three states of emergency. New results include the
compartmental model, described by a system of seven ordinary differential equations; proof
of positivity and boundedness of solutions; investigation of equilibrium points and their
stability analysis; computation of the basic reproduction number; and numerical simulations …
