RESUMO

This thesis deals with the leptospirosis endemics that occurred in the city of São Paulo during 2006. The goal of this work is to list and prioritize spatial features of the most affected areas and is accomplished by entering a spatial bias using a Geographic Information System. Those areas identified as high-risk are further displayed on a map in order to establish a relationship between the disease and the geographic space. After performing a brief spatial analysis of the endemic areas, the Eastern Zone of the city of São Paulo stood out as most prominent for the implementation of the following geographic method. Physical and social aspects are examined jointly through a geographic matrix using chorological and spatial approaches of the geographic space. Geographic Information Systems make possible the configuration of a study based on the weight of evidence, an elaboration of the event probabilities of a phenomenon a priori, without intervention, and a posteriori, with new probabilities of occurrence after the insertion of new information. Such information in this work receives the label of information plans. In order to deal with eastern São Paulo s endemics, the following information plans were used in the model: land use, slope, hydrological network, and census tracts containing the number of homes that discharge their waste into rivers or abandoned land. These information plans are put into practice using ArcSDM3.1 software in order to identify, through the weight of evidence, which ones contribute the most to the spread of the disease. After listing the information plans most important constituents in regard to the phenomenon, a probability map is created, which identifies what areas within East São Paulo represent the greatest risk of spreading the disease
