A novel fractional compartmental mathematical model was proposed to study the spread of COVID-19, with a focus on the transmissibility of super-spreaders. Numerical simulations were conducted for the regions of Galicia, Spain, and Portugal, revealing different values of the Caputo derivative order and highlighting the importance of considering fractional models.
A fractional compartmental mathematical model for the spread of the COVID-19 disease is proposed. Special focus has been done on the transmissibility of super-spreaders individuals. Numerical simulations are shown for data of Galicia, Spain, and Portugal. For each region, the order of the Caputo derivative takes a different value, that is not close to one, showing the relevance of considering fractional models. ? 2021 Elsevier Ltd.
