Aglomerados espaciais e espaço-temporais de tuberculose em município do Nordeste Brasileiro

The objective was to detect spatial and spatiotemporal clusters of tuberculosis in a municipality in northeastern Brazil that is a priority for disease control. This is an ecological study, in which new cases of tuberculosis that occurred in Imperatriz (MA), between 2009 and 2018, were collected from the Notifiable Diseases Information System. Scanning statistics was used to detect the spatial and spatiotemporal clusters of the cases. Three spatial clusters of high relative risk (RR) were identified: cluster 1 (RR = 2.10), cluster 2 (RR = 2.20) and cluster 3 (RR = 2.70). The spatiotemporal analysis showed two spatiotemporal clusters of high relative risk, cluster 1 (RR = 2.80) that occurred between 01/01/2009 and 12/31/2013 and cluster 2 (RR = 3.40) occurring between 01/01/2009 and 12/31/2010. Such findings point to the need to elaborate procedures for combating and controlling risk areas, considering the evident socio-spatial inequalities present in the municipality under investigation.
