Using Differential Transform Method for Solving COVID-19 Model

This paper aims to use the differential transform method (DTM) to find an approximate solution for a fractional differential system of (COVID-19) consisting of five equations in disease-sensitive S(t), exposed individuals E(t), infected patients I(t), recovered patients R(t) and death F(t) which Zahraa was solved it by Sumudu Adomian decomposition method and Fractional linear multi-step method. The approximate solution by DTM is in series form. Graphs are given to show the accuracy of the method. The approximate solution is evaluated by the differential transform method and this solution is in a series form. For each of the three values of the fractional order derivatives
$\mathfrak{c}x=0.6, \alpha=0.8$
and
$\alpha=0.9$
we evaluate three approximate solutions for disease-sensitive S(t), exposed individuals E(t), infected patients I(t), recovered patients R(t) and death F(t), three graphs are given for S(t),E(t)&I(t) for the values of
$\alpha=0.6, \alpha=0.8$
and
$\alpha=0.9$
to show the accuracy of the method.
