Fig. 6.

Results of the A-SIR model, Eqs.  (1) with initial conditions (12) and parameters ${\gamma }_s=1∕7$, ${\gamma }_a=1∕21$, $\mu =0.5$, $\xi =0.1$, ${\lambda }_{+}=0.3216$, $\omega =0.051$. The latter two were chosen to minimize the cost function, $c_{14}$, using the former four parameters. The blue dots correspond to the number of deaths reported in pandemic data divided by $\omega$. The graph of $S\left(t\right)$ lies out of the range shown in the figure. (For interpretation of the references to color in this figure legend, the reader is referred to the web version of this article.)
