Dependence of the equilibrium fraction infected (A) and correlations (:(B),

, expected in most social infections, there is no longer a threshold (
) needed for the infection to invade the population. The network causes infected individuals to cluster
away from susceptible individuals
, and this is more pronounced for larger
and lower fraction infected. Parameters are
