[Border: problem or ressource in health for immigrants ? The exemple of French Guiana].

The health of migrants is a complex issue in public health. In French Guyana, as elsewhere, globalization, through migrants in particular, has transformed the care of diseases previously geographically distant. In this context, the borders now concern the entire territory and not just the peripheries. These borders contribute to the aggravation of the migrants health determinants through the complex and sometimes risky paths that they generate. Transboundary areas are also areas of high vulnerability. However, these cross-border spaces and routes can also constitute health resources, in the original interfaces that they can produce in terms of cooperation promoting shared screening and monitoring programs.
