Fig. 2

The values of the parameters t1 and t2=t1+Δt for 50 countries, obtained by fitting the FSIR model with data up to 28 April 2020. The dashed lines give the average values of the parameters, ⟨t1⟩ (red) and t2=t1+Δt (blue) of the FSIR model defined by Eq. (3). The countries with labels are used to examine the behavior of the model in more detail. (For interpretation of the references to colour in this figure legend, the reader is referred to the web version of this article.)
