This presentation will focus on the dengue and chikungunya viruses, which are two of the most common vector borne diseases affecting urban areas around the world. In India and Delhi, these two viruses are spreading rapidly, infecting lakhs of individuals every year. The aim of this study is to underline 1) the geography of these diseases over several years in Delhi 2) the factors that lead to continuous spread within endemic cities –from urban complexity to political organization of urban/epidemic responses. After presenting some short term solutions that can help in controlling disease diffusion, this presentation will be an opportunity to re-evaluate the links between evolution of cities, intra-urban environmental disparities and the issue of sanitation within urban areas.
