Résumé : Over the past few years. several infectious diseases affecting animals and/or humans have emerged in regions far from their traditional endemic areas. At the same time, some critical vectorial diseases are in extension or intensification in tropical countries. These emerging dynamics can be regarded as consequences of global change and modifications in ecosystems condition. Changes in the distribution and abundance of insects are likely to be amongst the most important and immediate effects of climate change. Locally, human growing populations, evolution in agricultural practices, land use and new activities change the landscapes and insects' habitats and affect the epidemiological patterns. Opening up of borders, liberalisation of exchanges and an increase in contacts and movements of humans and animals for commerce and tourism break down the ecological, physical and regulatory barriers which had limited the spread of pathogens. Finally, in some countries, the lack of high-performance epidemiological surveillance structures, the degradation of research and health systems considerably increases the risks of introducing or spreading these diseases in naive countries. Some example on actual emerging diseases (Bluetongue, West Nile Fever, Rift Valley Fever) are presented to illustrate the main topics of current researches conducted on introduction ways, amplification processes and implantation of exotic pathogens and vectors. Innovative tools (GIS, models, remote sensing data), multidisciplinary and integrated approach, co-ordinated international collaborations are deployed to inventory, the most likely hot-spots, propose predictive scenari and promote surveillance and early warning tools. Recently proposed at the EU, the EDEN (Emerging Disease European Network) integrated project gathers the main partners in North and South countries to face this new challenge. (Texte intégral)
