A modelling approach to vaccination and contraception programmes for rabies control in fox populations

Christelle Suppo, Jean-Marc Naulin, Michel Langlais, Marc Artois


In a previous study, three of the authors designed a one–dimensional model to simulate the propagation of rabies within a growing fox population; the influence of various parameters on the epidemic model was studied, including oral–vaccination programmes. In this work, a two–dimensional model of a fox population having either an exponential or a logistic growth pattern was considered. Using numerical simulations, the efficiencies of two prophylactic methods (fox contraception and vaccination against rabies) were assessed, used either separately or jointly. It was concluded that far lower rates of administration are necessary to eradicate rabies, and that the undesirable side–effects of each programme disappear, when both are used together.
