Introduction:The objective was to identify space and space-time risk clusters for the occurrence of deaths in a priority city for the control of tuberculosis (TB) in the Brazilian Northeast. Methods: Ecological research was undertaken in the City of São Luis/ Maranhão. Cases were considered that resulted in deaths in the population living in the urban region of the city with pulmonary TB as the basic cause, between 2008 and 2012. To detect space and space-time clusters of deaths due to pulmonary TB in the census sectors, the spatial analysis scan technique was used. Results: In total, 221 deaths by TB occurred, 193 of which were due to pulmonary TB. Approximately 95% of the cases (n=183) were geocoded. Two signifi cant spatial clusters were identifi ed, the fi rst of which showed a mortality rate of 5.8 deaths per 100,000 inhabitants per year and a high relative risk of 3.87. The second spatial cluster showed a mortality rate of 0.4 deaths per 100,000 inhabitants per year and a low relative risk of 0.10. A signifi cant cluster was observed in the space-time analysis between 11/01/2008 and 04/30/2011, with a mortality rate of 8.10 deaths per 100,000 inhabitants per year and a high relative risk (3.0). Conclusions: The knowledge of priority sites for the occurrence of deaths can support public management to reduce inequities in the access to health services and permit an optimization of the resources and teams in the control of pulmonary TB, providing support for specifi c strategies focused on the most vulnerable populations.Keywords: Pulmonary tuberculosis. Spatio-temporal and spatial analysis. Death.Tuberculosis (TB) is one of the main causes of death among infectious contagious diseases and occurs mainly in developing countries (1) . In 2012, 1.3 million people died of TB worldwide. Brazil ranked 16 th in the number of cases and 109 th in terms of incidence rate(1) , with 36.1 cases per 100,000 inhabitants and a mortality rate of 2.4 deaths per 100,000 inhabitants (2) .It is notable that among the clinical forms of the disease, pulmonary tuberculosis (PTB) is on the list of avoidable causes of death because if the local health services established appropriate health promotion, protection and recovery actions for patients and their families, deaths from TB would be less common (3) .Considered a social disease (4) , TB should be studied from a microregional, local and focal viewpoint, according to the spatial distribution (5) . Therefore, a geo-epidemiological approach to the disease, using geoprocessing techniques, has been adopted in the international sphere (6) (7) (8) (9) (10) (11) (12) (13) (14) (15) (16) (17) . Nevertheless, the introduction of this technology to support the action planning and decision making of health managers and workers is still restricted (18) .In Brazil, a series of studies was undertaken that considered the incidence of the disease and undoubtedly contributed to a better understanding of its dynamics in distinct territories (19) (20) (21) (22) (23) (24) (25) (26) (27) (28) ...
