For a general class of models, we prove the global asymptotic stability (GAS) of the disease free equilibrium (DFE) under general assumptions. These conditions are related to the basic reproductive ratio . We also give a practical algorithm to compute a threshold condition equivalent to . We show that these two results can be applied to numerous epidemiological models from the literature.
Pour une classe générale de modèles, nous prouvons la globale asymptotique stabilité de l'équilibre sans maladie sous des hypothèses générales. Ces conditions sont relatives au nombre de reproduction de base . Nous donnons également un algorithme pratique permettant d'établir une condition de seuil équivalente à . Nous montrons que ces deux résultats peuvent être appliqués à de nombreux modèles épidémiologiques de la littérature.
