Summary : Birds have been able to colonize various available habitats in the world, from the Arctic continent to sub-Saharan Africa. They are also the reservoir of many pathogens: bacteria, parasites and viruses. Because of their migrations, they ensure the link between very different geographic areas and promote or contribute to the circulation of pathogens. Within this framework, the elaboration of a conceptual spatial and temporal model of the distributions of birds is the first step toward a better understanding of the role played by birds in the epidemiology of diseases. In the context of West Nile disease, an arboviral disease involving mosquitoes as vectors and birds as reservoirs, we have elaborated a model for spatial dynamics of a reservoir species to better understand the epidemiology of this disease in the Camargue region where the disease appears periodically as an epidemic/epizootic. This analysis allows us to determine biotopes and periods at risk and assess a risk index for reservoir – vector contact. |
