Disease on contact layer + awareness on info layer — epidemic threshold shifts
Infected: — |
Aware: — |
R₀_eff = —
Two-layer multiplex: disease (SIS) spreads on the contact network, awareness (UA) spreads on the
information network. Aware nodes have reduced infection probability (1−δ)β.
Above threshold, epidemic survives; awareness raises the epidemic threshold.
Blue = susceptible, red = infected, yellow = aware+susceptible, orange = aware+infected.
