Table 1.

The values of the various parameters that enter in the FSIR model of Eq. (3), for the 10 countries considered (see text for details). The countries have been indexed according to their N_T values, scaled by the population of each country. The next-to-last column includes the values for the expected total number of cases N_T when the number of infections has dropped to near zero, and is an extrapolated value (rounded to the nearest 100). The last column includes the number of days D (counting from April 28) until the value of N_T has reached 99% of its final value; a negative number (for China, Australia, Switzerland, and Greece) indicates that this date has already passed.
