Abstract (English): Introduction: It is difficult to adapt or generate new strategies for dengue control in rural areas, because of the dispersion of rural homes and the lack of knowledge of vector presence and behavior in these areas. Spatial data analysis could help to understand the temporal and spatial dynamics related to the transmission of vector-borne disease in rural areas and, thus, contribute to dengue prevention and control. Objective: Determine the likelihood of presence of the dengue vector, Aedes aegypti, in rural area of Anapoima and La Mesa municipalities, central Colombia. Materials and methods: A total of 102 houses were visited in the rural area, inspecting potential breeding sites of the Aedes aegypti and capturing adult forms inside these houses. The likelihood of the presence and absence of the vector in the study area was identified by indicator kriging, a spatial statistics interpolation technique. Results: The resulting prediction shows that the highest likelihood of presence of A. aegypti was close to urban centers in the central part of the study area. Conclusion: This study shows that analyses of spatio-temporal dynamics of disease vectors may be used in surveillance systems of vector-borne diseases, complementing currently used methods, and improving the identification of areas targeted for vector control interventions, thereby saving costs.

Abstract (Spanish): Introducción. Es difícil adaptar o generar nuevas estrategias para el control del dengue en áreas rurales, debido a la dispersión de los hogares rurales, a la falta de conocimiento de la presencia y comportamiento del vector en estas áreas. El análisis de datos espaciales podría ayudar a comprender las dinámicas temporales y espaciales, relacionadas con la transmisión de enfermedades transmitidas por vectores en las zonas rurales y, por lo tanto, contribuir a la prevención y control del dengue. Objetivo. Determinar la probabilidad de presencia del vector del dengue, Aedes aegypti, en el área rural de los municipios de Anapoima y La Mesa, centro de Colombia. Materiales y métodos. Se visitaron 102 viviendas del área rural, inspeccionando los criaderos potenciales para el mosquito A. aegypti y capturando las formas adultas al interior de estas viviendas. La probabilidad de la presencia y la ausencia del vector en el área de estudio se identificaron mediante la técnica de interpolación espacial del indicador kriging. Resultados. La región con mayor probabilidad para la presencia del vector se encuentra en la parte central en cercanía a los centros urbanos de los dos municipios. Conclusión. Este estudio muestra que los análisis de las dinámicas espaciotemporales de los vectores de enfermedades, pueden utilizarse en sistemas de vigilancia de enfermedades transmitidas por vectores complementando los métodos usados actualmente, optimizando la identificación de las áreas objeto de intervención vectorial y de esta manera ahorrar costos.
