Abstract
This article sought to analyze the occurrence of congenital syphilis in the regions of Brazil in the period 2010-2018. Most cases of the disease occur because the mother during prenatal care was not tested for syphilis or because the treatment recommended by the Ministry of Health was not performed properly before or during pregnancy. This is a study whose data collection instrument was the Ministry of Health's Notifiable Diseases Information System (NDIS). The variables used were area of residence, education, prenatal care, race, partner treatment, final classification of syphilis. The present study corroborates the persistence of the high prevalence of cases of congenital syphilis in several Brazilian regions. Its occurrence has been increasing in recent years: 2017 (24,666 cases), 2018 (26,219 cases) and is associated with inadequate case management, low socioeconomic and sociodemographic levels, in addition to the low quality of prenatal care received by pregnant women. It was also emphasized that the partner's low adherence to treatment was related to social causes and the increase in cases of congenital syphilis.
