Human Trypanosoma cruzi infection is driven by eco-social interactions in rural communities of the Argentine Chaco.

ABSTRACT: The transmission of Trypanosoma cruzi to humans is determined by multiple ecological, socio-economic and cultural factors acting at different scales. Their effects on human infection with T. cruzi have often been examined separately or using a limited set of ecological and socio-demographic variables. Herein, we integrated the ecological and social dimensions of human infection risk with the spatial distribution patterns of human and vector (Triatoma infestans) infection in rural communities of the Argentine Chaco composed of indigenous people (90% Qom) and a creole minority. We conducted serosurveys in 470 households aiming at complete population enumeration over 2012-2015. The estimated seroprevalence of T. cruzi prior to the implementation of an insecticide spraying campaign (2008) was
