Dengue and other Aedes aegypti mosquito-borne illnesses like Zika and chikungunya are serious public health concerns in the world’s tropics. Improved mosquito control could dramatically reduce the prevalence of these diseases, but due to a lack of surveillance data, efforts to reduce mosquitos are currently inefficient and poorly targeted. To promote better understanding of the links between climate, mosquito abundance, and dengue infections, this project will develop improved models that use satellite imagery to predict the climate suitability for dengue transmission.  With this new information, the project can inform current decision-making procedures on where to spend limited resources for mosquito control such as insecticides and help reduce transmission of the disease.
