RESUMEN

La enfermedad de Chagas es un problema de salud pública de mayor importancia en America latina, causado por el parásito protozoario Trypanosoma cruzi y transmitido por insectos hematófagos de la subfamilia Triatominae. El control está basado en el control de los insectos domésticos con insecticidas y con el mejoramiento de los domicilios. Como para otras enfermedades transmitidas por vectores, la identificación de las zonas de alto riesgo de transmisión del parásito es de gran importancia para la planificación e implementación de programas de control eficientes. En este estudio exploramos las relaciones entre la distribución geográfica de Triatoma dimidiata y factores bioclimáticos en la península de Yucatán, México, utilizando sistemás de información geográfica, y desarrollamos modelos predictivos de la abundancia de T. dimidiata en los domicilios y de su tasa de infección por T. cruzi. Utilizamos estas predicciones para la elaboración del primer mapa de riesgo de transmisión natural de la enfermedad de Chagas en la península de Yucatán, una heramienta de gran utilidad para la implementación de programas de control en la región.
