Academic research in Brazil has identified significant public health concerns, including rising rates of gestational and congenital syphilis in the Baixada Santista region, particularly among young women. Other studies highlighted correlations between human and bovine tuberculosis and investigated the potential toxicity of glyphosate-based herbicides.

In response to these health challenges, municipal authorities have begun implementing targeted interventions. In Porto Velho, strengthened prenatal care and increased monitoring of pregnant women led to a 52.3% reduction in congenital syphilis cases between 2021 and 2025. Additionally, in Petrolina, local government efforts include organizing professional symposiums to improve diagnostic and treatment strategies to eliminate vertical transmission.
