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…
Overcoming Repeated Testing Schedule Bias in Estimates of Disease Prevalence
Patrick M. Schnell, Matthew Wascher, Grzegorz A. Rempala
During the COVID-19 pandemic, many institutions such as universities and workplaces implemented testing regimens with every member of some population tested longitudinally, and tho…
Likelihood-Free Dynamical Survival Analysis Applied to the COVID-19 Epidemic in Ohio
Colin Klaus, Matthew Wascher, Wasiur R. KhudaBukhsh +1
The Dynamical Survival Analysis (DSA) is a framework for modeling epidemics based on mean field dynamics applied to individual (agent) level history of infection and recovery. Rece…
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…
