Specifically, this project is designed to use remote sensing imagery to characterize the landscape elements associated with transmission of Leishmania chagasi and the presence of the sandfly vector and canine reservoir hosts. Satellite data will be integrated with demographic, ecological, and parasitological data collected on the ground to construct predictive models to discriminate areas at high and low risk for transmission. These models will be evaluated prospectively for their ability to detect foci of transmission, anticipate epidemics, and direct interventions for control. We expect the results of this pilot study will justify confinued use of remote sensing for purposes of surveillance and research on transmission of kala-azar throughout Brazil.
