Intestinal parasitoses are a major concern for public health, especially in children from middle and low-income populations of tropical and subtropical areas. We explored the environmental and socio-demographic characteristics of the persistence of parasites in children and their environment in Puerto Iguazú, Argentina. Copro-parasitological status of 483 asymptomatic children was assessed. Through questionnaires and census data, we characterized the socio-demographics conditions at an individual, family and neighborhood levels. Simultaneously, a design-based sampling of 744 soil samples and 530 dog feces was used for characterize the environmental contamination. These data were combined in multi-level models and were compared hierarchically using the Akaike Information Criterion corrected for small samples (AICc). We applied generalized linear mixed-effects models (GLMM) that included households and neighborhood as random effects to consider the dependence of the data and nested factors (child
