Susceptible-Infected-Susceptible dynamics with mitigation in connection of infected population (2501.04463v1)

Abstract: The susceptible-infected-susceptible epidemic model is analyzed through a degree-based mean-field approach. In this work, a mitigation factor is introduced in the probability of finding an infected individual following an edge. This modification simulates situations where the infected population reduces its participation in the dynamics of disease propagation, as may happen with the seclusion or hospitalization of infected individuals. A detailed investigation of this new model and its comparison to the original one (without the mitigation factor) was performed on the Barab\'asi-Albert network, where some important results were analytically accessible.
