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 fo… Show more

“…Anthropogenic intervention has been hypothesized to increase contact between triatomines and humans [43]; however, the greater abundance of wild triatomines in a particular habitat does not necessarily translate into increased Chagas disease risk for humans because socioeconomic and human behavioral factors are also important to consider [18]. Nevertheless, the risk posed by the ability of bugs to invade human dwellings cannot be neglected, because it increases the chances of vector–human contact, the recovery of interrupted domestic transmission cycles [2, 8, 18, 4446].…”

“…En la vigilancia epidemiológica a nivel de la salud pública, es necesario e importante ampliar los diálogos entre la población en riesgo o que está afectada y las instituciones encargadas del tema, con el fin de involucrar la población de una forma activa en el diagnóstico para medir factores de riesgo y en el planeamiento de las posibles soluciones (34,36). Aunque no se hizo una búsqueda activa del vector dentro de las viviendas, por no ser el objetivo en el presente estudio, dentro de la encuesta epidemiológica se observó que, de 103 familias encuestadas, 64 contestaron haber visto el vector alguna vez dentro de la vivienda.…”

“…Aunque no se hizo una búsqueda activa del vector dentro de las viviendas, por no ser el objetivo en el presente estudio, dentro de la encuesta epidemiológica se observó que, de 103 familias encuestadas, 64 contestaron haber visto el vector alguna vez dentro de la vivienda. Por los resultados obtenidos en la población humana y los reservorios domésticos, se pudo inferir que hay una movilidad de R. pallescens en esta zona y que todas las condiciones físicas y socioeconómicas, así como el manejo del medio ambiente, pueden estar influyendo en la dinámica de esta especie (36).…”

“…In the People's Republic of China, the genetic discontinuity of the intermediate host snails of schistosomiasis was shown to be ultimately influenced by landscape ecology (Li et al, 2009), while Dongus et al (2009) expose how agricultural and geographical features influence the presence of Anopheles larvae in urban areas in Dar es Salam, Tanzania. Some authors (Beck et al, 2000;Kitron, 2000) recommend spatial analysis and utilisation of the potential of GIS for infectious disease management, while others (Romaña et al, 2003) have conceptualised the epidemiological landscape notion in a way that underlines the importance of ecology. The idea of epidemic foci as part of landscape ecology is of paramount interest for our approach, as it holds that persistence of endemicity in a geographical locality is supported, indeed ensured, by environmental and edaphic (soil characteristic) conditions furthering the coexistence of parasite, vector and host (Romaña et al, 2003).…”

Barrera et al, (1998) studied a malaria hotspot with strong transmission in Venezuela from that point of view, and this research group also applied this approach to characterise an epidemic of hemorrhagic dengue fever in this country (Barrera et al, 2000).…”
