On the Effects of Innate Immunity on Epidemic Dynamics
Gorm G. Jensen, NBI

Seasonal epidemics is a well known phenomenon to most of us, and a very well studied one as well. A common model used for the theoretical studies is the SIRS-model which excels in simplicity and intuitiveness, but disappoints by it's lack of ability to actually predict sustained epidemic behaviour. I will briefly discuss how this problem can be overcome by introducing the so called SIRnS-model. Then I will extend the the mode even further by introducing multiple diseases, interacting via a short lived innate (or general) immunity. And finally I will use simulations to discuss the effects of this interaction on global dynamics of each disease.
