Left: Estimates of $\overline{\gamma }$ (filled x symbols) and 1/Δt (filled circles) for the 10 countries considered in Table 1; these values are useful in estimating the reproduction number ${\overline{R}}_0$. Right: Estimated values for the reproduction number ${\overline{R}}_0$ for the 10 countries considered, as obtained from the FSIR model. The larger the value ${\overline{R}}_0,$ the more adversely affected by the disease the country is.
