Genuine and spurious bistability in a simple epidemic model with waning immunity
Francesca Scarabel, Harry Coldwell, Tyler Cassidy
We study an infection-age structured epidemic model in which both the infectivity and the rate of loss of immunity depend on the time-since-infection. The model can be equivalently…

Bistability and complex bifurcation diagrams generated by waning and boosting of immunity
Francesca Scarabel, Mónika Polner, Daniel Wylde +2
We investigate an epidemiological model that incorporates waning of immunity at the individual level and boosting of the immune system upon re-exposure to the pathogen. When immuni…
