The sketch of the two-layer network used in our SIR-UAU model and the schematic illustration of the SIR-UAU dynamics in that two-layer network. (A) The upper layer represents the information dissemination, where each node has two possible states: aware (A, blue nodes) or unaware (U, gray nodes). The lower layer represents the physical contact network, in which nodes have three possible states: susceptible (S, green nodes), infected (I, red nodes) or recovered (R, pink nodes). There is a one-to-one mapping between nodes in two layers, to represent the same individual in each layer. (B) The upper row presents the unaware SIR and the lower row corresponds to the aware SIR.
