Active risk aversion in SIS epidemics on networks

no code implementations • 3 Nov 2023 • Anastasia Bizyaeva, Marcela Ordorica Arango, Yunxiu Zhou, Simon Levin, Naomi Ehrich Leonard

We prove that the model, with these two networks and populations using risk aversion strategies, exhibits a transcritical bifurcation in which an endemic equilibrium emerges.

We derive an exact upper bound on the epidemic overshoot for the Kermack-McKendrick SIR model.
