    ..Landscape ecology could assist in understanding the impact of these urban structures on control activities and the persistence of transmission. ..

    ..cruzi blood sampling into existing interventions for zoonotic disease control (e.g., rabies vaccination programs) can be an effective method of increasing surveillance and improving understanding of disease distribution. ..

    ..cruzi through vector colonies and create a considerable force of infection for a pathogen whose transmission might otherwise fizzle out. ..

    ..These coverage estimates suggest that prior analyses of the relative risk of measles associated with vaccine refusal underestimate that risk by an order of magnitude of 2-10 times. ..

    ..infestans, were associated with infestation. Spatial clustering of infestation in the urban context may both challenge and inform surveillance and control of vector reemergence after insecticide intervention. ..

    ..Our findings suggest that the common bed bug may be a competent vector of T. cruzi and could pose a risk for vector-borne transmission of Chagas disease. ..

    ..This heterogeneity in infectiousness has strong implications for T. cruzi transmission dynamics and control, as super-shedder guinea pigs may play a disproportionate role in pathogen spread. ..
