The incidence rate of tuberculosis in Olinda (PE) is almost twice the national level. On average, 300 new cases are registered in the county each year. To understand the numbers in the city, researchers at the Federal University of Pernambuco (UFPE) developed a statistical study.

The conclusion of the research shows that the sources of contamination are in sectors with low income and low education, but are distinguished from other census tracts with similar characteristics to the high number of female household heads with no education and with income less than the minimum wage. The study also provides the link between the persistence of the disease in the community and high household density.

To find the pathways of the disease, the research drew georeferencing of annual new cases of tuberculosis in Olinda in relation to city census tracts, defined at each census by the Brazilian Institute of Geography and Statistics (IBGE). These units correspond to specific regions containing 1200 inhabitants or 300 households.

In the census of 2000, Olinda was divided into 299 sectors by the IBGE. The study analyzes the correlation in space and time for the new tuberculosis cases between 1996 and 2000, based on monthly reports. The results show that 82% of the sectors that make up the outbreaks have more than one case per family, or both retreatment cases, 90% are located in areas of low income or low education, and 90% have an average of ten cases of the disease during five consecutive years.

For the professor of the Physics Department of UFPE Zorzenon Rita Maria dos Santos, one of the organizers of the study, this type of information can contribute to improved allocation of funds, drug delivery, recruitment and human resources planning vaccination programs. Besides its usefulness in the case of tuberculosis, which kills one person every 15 seconds worldwide, the methodology can be applied to the study of other diseases or other social processes.

Tuberculosis hits 30% of world population and kills three million people every year. In Brazil, there are between 35 and 45 million infected people (almost 25% of the population), with 100,000 new cases and five to six thousand deaths per year (data from 1981 to 2000). According to the Virtual Health Library of the Health Ministry, it is an infectious disease caused by a bacterium that affects the lungs but can also occur in other body organs, bones, kidneys and meninges.
