Abstract : The asian highly pathogenic avian influenza outbreak allowed the scientific community to understand that proximity between sensitive hosts was of key concern to study the transmission of such an infectious disease. One of the most dangerous epidemiologic situation is for example Free Living Birds markets.The main hypothesis is that transmission is due to a direct or indirect contact between domestic birds and wild waterfowl as free ranging is the most common breeding technics.The Rhône Alpes region and more particularly the Dombes area is a french area which offers the environmental conditions to insure this proximity.The polutry industry is well developed with numerous free ranging farms. This is also a wetland which is used by a large population of wild waterfowl species as a wintering and breeding site.We assess here the risk of an outbreak of highly pathogenic avian influenza both in wild and domestic populations in the environmental context of the Dombes area. We propose methological tools to understand the introduction, circulation and transmission between different host populations of such an infectious disease in a particular environmental context. Our study is performed at a temporal and geographical scale. We use GIS (Geographical Information System) technics and modelling to propose risk maps and predicitive data and also classical epidemiological tools as an epidemiological survey to better understand the interaction between reservoir and target populations.
