Main theme 1 : Circulating zoonotic pathogens

The Camargue, rich in biodiversity and a migratory crossroads between Africa, Europe and the Mediterranean, is a strategic area for studying the emergence of zoonotic diseases. In recent years, there has been a resurgence of viruses such as West Nile, Usutuor H5N1and the emergence of indigenous cases of Dengue, Chikungunya and Zika, en lien avec l’implantation du moustique tigre. Toute épidémie infectieuse débute par l’exposition répétée d’un hôte à un pathogène circulant dans l’environnement. La Camargue combine une biodiversité microbienne dense et une forte activité humaine (élevage, pêche, agriculture, tourisme), créant de nombreuses opportunités de contact et de transmission. Le territoire abrite aussi des invertébrés clés dans les cycles de vie de nombreux pathogènes (moustiques, escargots d’eau douce), soulignant l’importance de comprendre where these infectious agents circulate, what reservoirs they have and what are the risks of exposure for humans and animals? This area is part of a One Health preventive approach One Healthintegrating human, animal and environmental health. It also addresses interrelated issues such as antibiotic resistancein line with local infectious risk dynamics.
