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 Zikalinked to the introduction of the tiger mosquito. Any infectious epidemic begins with the repeated exposure of a host to a pathogen circulating in the environment. The Camargue combines dense microbial biodiversity with a high level of human activity (livestock farming, fishing, agriculture, tourism), creating numerous opportunities for contact and transmission. The area is also home to invertebrates that are key to the life cycles of many pathogens (mosquitoes, freshwater snails), underlining the importance of understanding how these pathogens are transmitted: 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.
