Proposal description : Infectious diseases of livestock impact animal health and food safety, and cause economic losses to the animal production sector. Their effective control is a major issue for sustainable livestock farming and competitive agri-food chains, but also for veterinary public health. In a currently globalised production system, where farms are highly interconnected through animal trade and via a variety of direct and indirect pathways allowing pathogen spread (contact at pasture, pathogen spread by the wind), control need to be considered at large scales. A better understanding of pathogen propagating pathways between farms is needed. This involves the uncovering of the network of livestock movements, which is often the main driver of infection spread, and of the role played by trade exchanges in epidemic and endemic situations. This project aims at (i) investigating the characteristics of cattle-trade networks driving pathogen spread, by adapting existing appropriate tools for the analysis of dynamical networks or building new ones, (ii) exploring the relative contributions of transmission pathways of infections unfolding on contact dynamical networks and evaluating control strategies with respect to generic characteristics of endemic infectious diseases of cattle. This project extends our current work in two directions. First, it continues the study of cattle movements in France spanning on several years (2005-2009), by elaborating and adapting appropriate tools for the analysis of dynamical networks, extending the temporal analysis of database to the national scale and diversifying the analysis with respect to relevant features. Second, it extends ongoing studies concerning the modelling of various pathogen spread causing endemic diseases in cattle by building a generic view.
