The objective of this work is to provide a sophisticated but accessible compartmental epidemic model. Our algorithm highly inspired from the model developed by Sofonea and al. in 2020. This has been used as reference for several working groups France during Covid-19 crisis. Each individual allocated compartment according her age, current state with respect disease, well length time she that sta...

This study approaches the analysis of stability epidemiological model SIR with loss immunity. is a given by system ordinary differential equations. Initially, we present and its interpretation. Then define constants elements that compose model, so results obtained using qualitative theory equations, especially planar systems related to dynamics fixed points. Finally, show representing globally ...
