Fig. 6.

In these graphics we present the active case solution for $t=2\tau$ (time in days), $D=1$, $\mathbf{x}={\mathbf{x}}^{\prime }$, ${\rho }_0=10^7$, ${\tau }^{\prime }=31.5$, ${\tau }_1=20.5$, $\alpha =0.27$, $s=1$, $\lambda =1$, $z=50$, and $\sigma =43$. We also depicted the active cases data from Spain (blue dots), since February 15, 2020 (day 1), until May 02, 2020 (day 78) [26].
