Crowded and warmer: Unequal dengue risk at high spatial resolution across a megacity of India


Olivier Telle (CNRS, IRASEC) published an article in collaboration with Researchers from Institut Pasteur Paris, New York and Buenos Aires Universities and Santa Fe Institute investigating the link between dengue and the urban and climatic environment of Delhi, India.

Creating a detailed map to pinpoint dengue hotspots based on temperature data and the density of mosquitoes per human, considering different socio-economic regions.

Key findings include the identification of high-risk areas during inter-epidemic periods, with densely populated and poorer (populations with less access to urban infrastructure) being more susceptible due to higher temperatures and mosquito carrying capacity. It underscores the need for targeted control efforts in these high-risk areas, especially during inter-epidemic periods, and highlights the inequality of dengue risk across urban landscapes. The research advocates for a better understanding of the interplay between climate factors and socio-economic conditions in managing vector-borne diseases.

This research has been funded by National Institute of Health (USA) and FACCTS program (University of Chicago).
