Epidemic Percolation Networks, Epidemic Outcomes, and Interventions

Table 1

Summary of the mass-action model from Section 4.1. Subpopulation A has high infectiousness but low susceptibility, subpopulation B has average infectiousness and susceptibility (by both arithmetic and geometric mean), and subpopulation C has low infectiousness but high susceptibility. Nodes in subpopulation B have the highest probability of being in the GSCC and the highest expected number of edges connecting them to other nodes in the GSCC.

Subpopulation	A	B	C
Mean outdegree (infectiousness)	5	2.5	1.25
Mean indegree (susceptibility)	1.25	2.5	5
Pr (causes epidemic)	.951	.779	.430
Pr (infected in epidemic)	.430	.779	.951
Pr (in GSCC)	.409	.607	.409
Mean degree within GSCC	.835	.942	.835
