Numerical implementation of a mathematical model (SEIRD) based on data from the spread of the fifth wave of COVID-19 in russia and regions

In the present paper, a fractional-order epidemic model with operator called the Caputo operator for the transmission of COVID-19 epidemic is analyzed. This model takes into account the following groups of people: susceptible (S), exposed (E), infected (I), recovered (R) and deceased (D). The model is called SEIRD, from the first letters of the names of the described groups. Calculations are based on public data on incidence in Russia and the following subjects: Moscow, St. Petersburg and Kamchatka Krai.
