Résumé
Abstract INTRODUCTION: Congenital syphilis is considered a severe public health problem because it accounts for approximately 40% of the perinatal mortality rates, 25% of stillbirths, and 14% of neonatal deaths, in addition to causing severe consequences for the fetus. This study aimed to describe the rates of congenital syphilis in children under one year of age in Brazilian capitals from 2009 to 2016. METHODS: Ecological time series study, using rates of congenital syphilis in children under one year of age and living in Brazilian capitals. The Prais-Winsten regression model was used to assess the trend. RESULTS: A total of 44,056 cases of congenital syphilis in children under one year of age were reported in Brazilian capitals between 2009 and 2016. The highest rate of congenital syphilis in children under one year of age occurred in 2016 in Porto Alegre (31.07/1,000 live births). The Northeastern capitals showed high rates, particularly the capital Recife (23.67/1,000 live births). CONCLUSIONS: Congenital syphilis represents a major challenge for public policies. The need for improvements in the quality of prenatal care is highlighted, as it is essential to reduce the alarming rates.
