Epidemics with avoidance and isolation on
Andrew Heeszel, Matthew Wascher
The contact process with avoidance is a generalization of the classical contact process (SIS epidemic) that introduces a mechanism for healthy individuals to avoid their infected n…

The effects of individual versus community-influenced isolation on SIS epidemic persistence on finite random graphs
Shirshendu Chatterjee, David Sivakoff, Matthew Wascher
The contact process, or the SIS epidemic model, is a continuous-time Markov process used to model the spread of a recurring infection on a graph. Each vertex is either healthy or i…

The effect of avoiding known infected neighbors on the persistence of a recurring infection process
Shirshendu Chatterjee, David Sivakoff, Matthew Wascher
We study a generalization of the classical contact process (SIS epidemic model) in a directed graph . Our model is a continuous-time interacting particle system in which at ever…
