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 with
official real data from the Portuguese health authorities. Besides completely
new, the proposed model allows to describe quite well the spread of COVID-19 in
Portugal, fitting simultaneously not only the number of active infected
individuals but also the number of hospitalized individuals, respectively with a
L2 error of 9.2152e ? 04 and 1.6136e ? 04 with respect to the initial population.
Such results are very important, from a practical point of view, and far from
trivial from a mathematical perspective. Moreover, the obtained value for the
basic reproduction number is in agreement with the one given by the Portuguese
authorities at the end of the three emergency states.
