Modeling Epidemics on Multiplex Networks: Epidemic Threshold and Basic Reproduction Number
Accurate epidemic forecasting requires models that account for the layered and heterogeneous nature of real social interactions. The basic reproduction number $\mathcal R_0$ calculated from models that assume homogeneous mixing or single-layer contact structures have limited applicability to complex social systems. Here, we propose an expression of $\mathcal R_0$ in the context of multiplex networks, enabling the analysis of disease transmission across multiple social layers. We adapt the Deg…
