Abstract
The map's usage and the concerns about geographic distribution related with diseases are not a recent issue. A classical example is the John Snow survey -maps were used to locate cholera's cases and related them with the water supplying. The spatial representation techniques are fewer used in health sectors due to troubles in managing such information. So, the aim of this survey was to establish the disease spatial distribution in Ribeirão Preto, 2002. Secondary data were used to elaborate this study. The spatial distribution of cases was realized by using the MapInfo 7.8 software. Although many cases were concentrated in the northeast region in the city, which consists the quarters of low economical income. The results contribute to show the Tb spatial distribution in Ribeirao Preto, they also reinforce the space category as a methodological alternative to manage, to monitor and to evaluate the health actions by directing interventions to decrease the iniquities.

Analyzing disease distribution and determinants in populations in space and time is an essential aspect of empidemiology
Snow reached conclusive results: while 37 deaths occurred among the 10,000 homes supplied by the Lambeth Company, there were 315 deaths in the 10,000 residences that had their water provided by the Southwark and Vauxhall Company
This study aims to present an example through the spatial distribution of Tuberculosis (Tb) cases according to home address in the urban area of Ribeirão Preto for the year 2002
Summary
Analyzing disease distribution and determinants in populations in space and time is an essential aspect of empidemiology. It involves primordial issues such as: Who became ill? Lambeth extracted water from the Thames River at a point before sewage was dumped into it, whereas Southwark and Vauxhall would collect their water after that point This was the perfect opportunity to check if the sewagecontaminated water caused cholera. Snow reached conclusive results: while 37 deaths occurred among the 10,000 homes supplied by the Lambeth Company, there were 315 deaths in the 10,000 residences that had their water provided by the Southwark and Vauxhall Company. He concluded that it is essential to first become acquainted with the facts in their most intimate details, and formulate a feasible causal explanation[1]
