description The urban phenomenon and the re-localization of pathogen complexes. More than half of a century has passed since the popularization of the concept of pathogen complex. During this time, the world urban population has been multiplied by five, compared to the rural population. The environmental changes led to ecological modifications in these dynamic systems, perceptible in the agents and vectors of the transmitted pathologies, which adopted new strategies of survival. A case study in the city of San Juan, Argentina, where the pathogen complex of the Chagas’ Disease registers transformations, is presented. Its vector, Triatoma infestans, gradually carries its populations from the surrounding rural environments to the city. To do this, it profits from an inter-specific relationship with doves (Columba livia), acting on them as parasite, and takes advantage of their mobility.
