La dynamique de la dengue à Santa Cruz de la Sierra (Bolivie) entre paysages à risques et mobilités

Between Spaces at Risk and Mobilities : Appreciation of the Inequalities and Risk Management Dengue fever, transmitted by the aedes vector, is most prevalent in urban environments because of the ecological requirements of its vectors that reproduce in the multiple water collections generated by the city and its inhabitants. However the diversity of urban landscapes seems to determine the heterogeneous distribution of the disease across the urban landscape. Across the world, the diffusion of the disease is due in part to urban development, especially to uncontrolled development, and on the acceleration of population displacements. This study explores whether these large-scale processes are also at play at a more local scale, using the city of Santa Cruz de la Sierra, in Bolivia, as a case study. This city of a million and half of inhabitants is rapidly growing and is at the crossroads of circulation ; it is the epicentre of the disease in Bolivia. We examine the interaction between the various levels of risk factors influencing the disease and inequalities in its distribution. We discuss implications of the results for the development and implementation of urban policies, highlighting the importance of considering health hazards in their formulation.
