Joan Saldana: Awareness in network epidemic models

Human behavioural responses have an important impact on the spread of epidemics. One way to incorporate them into epidemic models has been to consider that individuals are aware of the risk of contagion and adopt preventive responses when they get informed about the existence of the disease. The information dissemination can be modelled by means of a second network, with the same set of nodes as the contact network, over which awareness spreads. In this talk I present a toy model for epidemic spreading in the presence of awareness for which the epidemic threshold is expressed as a function of the overlap  between these two networks. Finally, I will discuss the suitability of this measure of the interrelation between pairs of networks when distinct architectures are considered.
