A nonlinear relapse model with disaggregated contact rates: Analysis of a forward-backward bifurcation

Autor: Jimmy Calvo-Monge, Fabio Sanchez, Juan Gabriel Calvo, Dario Mena

Publikováno v: Infectious Disease Modelling, Vol 8, Iss 3, Pp 769-782 (2023)

Throughout the progress of epidemic scenarios, individuals in different health classes are expected to have different average daily contact behavior. This contact heterogeneity has been studied in recent adaptive models and allows us to capture the i

\noindent We formulate an age-structured three-staged nonlinear partial differential equation model that features {\it nonlinear} recidivism to the infected ({\it infectious}) class from the {\it temporarily} recovered class. Equilibria are computed,
