Medio ambiente y protozoosis sistemicas III los vectores de la enfermedad de Chagas y su asociación con los factores climáticos

Chagas’ disease is a serious problem of public health in the latin American countries, caused by the protozoan parasite Trypanosome cruzi and transmitted by hematophagus insects of the subfamily Triatominae. As in other vector-borne diseases, Chagas’ disease is strongly influenced by bioclimatic variables. Currently, use of geographical information systems (GIS) is allowing to establish indexes that link vectors distribution with macroclimatic variables (vegetation, relative humidity, rainfall, annual mean temperature, etc) helping to identify in a more exactly way, the extention of higher risk areas for infestation, making more easiest its monitoring, surveillance and simplifying the efforts in the field data management for the generation of predictive models of entomological risk in the different endemic areas
