This study analyzed the epidemiological profile of pulmonary tuberculosis from 2007 to 2010 in municipalities (counties) in Mato Grosso do Sul State, Brazil, that border on Paraguay and Bolivia. In the border region, the incidence rate (49.1/100,000 inhabitants), mortality rate (4.0/100,000 inhabitants), and treatment dropout rate (11.3%) were 1.6, 1.8, and 1.5 times higher than in the non-border region. Among indigenous individuals in the border region, the rates for incidence (253.4/100,000 inhabitants), mortality (11.6/100,000 inhabitants), and HIV/TB co-infection (1.9/100,000 inhabitants) were 6.4, 3.2, and 1.9 times higher than in non-indigenous individuals in this region. Living in the border regions was inversely associated with HIV/TB co-infection. Indigenous ethnicity was associated statistically with not abandoning TB treatment. The study concludes that the population residing in these municipalities along the border is exposed to high risk of pulmonary TB and TB mortality and treatment dropout, thus requiring special health surveillance interventions.
