          Abstract

          Las modificaciones del paisaje causadas por las actividades y migraciones humanas contribuyen en hacer emerger o re-emerger enfermedades tropicales, particularmente aquellas cuya transmisión se realiza por insectos vectores que a menudo deben escapar a las condiciones cambiantes ambientales, adaptándose y modificando sus redes tróficas, su morfología, hasta su genotipo. Obtener una mejor comprensión de las relaciones entre los factores ecológicos y humanos y las antropozoonosis es vital para poder identificar variables que permitan cartografiar el riesgo para las poblaciones humanas. Este es el objetivo del programa de investigación Ecología del Paisaje, Dinámica de los Agro-Ecosistemas y Complejos Eco-Patógenos: La Definición del Riesgo Eco-Epidemiológico en la Tripanosomiasis Americana que se desarrolla en diferentes ecosistemas del Brasil. Los autores describen las bases conceptuales y metodológicas del programa e insisten sobre el rol del método eco-epidemiológico para el estudio de la estructura y el funcionamiento de los focos naturales y antropizados de la infección. Modelizar su dinámica espacial y temporal permite concebir nuevos útiles de predicción y de vigilancia.

          Translated abstract

          Modifications of the landscape by human activity and migratory movements contribute to the emergence or reemergence of zoonotic and human diseases, particularly those transmitted by insects which often escape the changing environmental conditions, adapting and modifying their trophic networks and morphology, including their genotype. A better understanding of relationships between ecological factors, human factors, and anthropozoonoses is vital to be able to identify variables that allow one to map the risk for human populations. This is the main objective of the research program Landscape Ecology, Land-Use Dynamics, and Eco-Pathogenic Complexes: Eco-Epidemiologic Risk in the Case of American Trypanosomiasis, developed in various Brazilian ecosystems. The authors describe the program's conceptual and methodological basis and highlight the role of eco-epidemiology for studying the structure and function of natural and anthropogenic foci of infection. Modeling spatial and temporal dynamics can help predict and monitor such tropical diseases.

          Emerging Chagas disease in Amazonian Brazil.

          In the Amazon Basin, Trypanosoma cruzi infection is enzootic, involving a variety of wild mammals and at least 10 of the 16 reported silvatic triatomine bug species. Human cases of Chagas disease are increasing, indicating that the disease may be emerging as a wider public health problem in the region: 38 cases from 1969 to 1992, and 167 in the past eight years. This article reviews the status of Chagas disease in Amazonian Brazil, including known reservoirs and vectors, and the genetic diversity of T. cruzi. At least three subspecific groups of T. cruzi-T. cruzilZ1, T. cruziZ3 and T. cruziZ3/Z1 ASAT--are present. It appears that T. cruzil has an extant capacity for genetic exchange. Attention is also drawn to the risk of domestic endemicity, in addition to the tasks facing the disease control authorities.

              Elimination of vector-borne transmission of Chagas disease

              The control of the vector-borne transmission of Chagas disease in Brazil was organized as a national program in 1975, when two large entomological and sero-epidemiological surveys were conducted in the country in order to identify areas at highest risk of transmission and to guide inerventions regarding the chemical treatment of domestic vectors of the disease. The authors present the baseline data gathered through these studies and compare them with more recent data. The evaluation performed shows that the transmission by Triatoma infestans is virtually interrupted and that the transmission by other native species of triatominae from different regions of the country is possibly very low. It is emphasized the need to maintain permanent actions of entomological surveillance in order to prevent recurrent transmission.
