^a∆N_T is the difference between N_T and the total number of cases that were infected by the first major subepidemic (for Sweden, Denmark, and Greece, both the small initial wave and the second wave have been taken into account). ∆N_T has also been normalized by the country’s population in millions.

^bN_T is the asymptotic value after all waves have decayed, given in Table 1, normalized here by the country’s population in millions.
