Concentration of removeds at the end of SIR epidemics as a function of the inherent transmission rate, α.
The initial concentration of ignorants is
and the removal rate is
. Symbols indicate the results of MC simulations for ER networks of size
and
(103 realizations of epidemics for each value of α; all the epidemics run on the same random graph). Different colours correspond to different values of β, as marked by the colour-box. Lines show the analytical solutions of the synergistic SIR mean-field model. A magnified view of the onset of the discontinuity for
is displayed in the inset.
