Abstract: Congenital syphilis (CS) is an infectious disease caused by the vertical transmission of Treponema pallidum, representing an important indicator of the quality of prenatal care and maternal–child surveillance. Despite being preventable, its persistence highlights gaps in screening, early diagnosis, and proper follow-up of pregnant women. The aim of this study was to analyze the incidence of CS in the state of Pará between 2020 and 2024, relating it to prenatal care coverage and clinical outcomes in newborns. This is an epidemiological, descriptive, and retrospective study, based on secondary data from the Notifiable Diseases Information System (SINAN), provided by DATASUS. All reported cases of CS during the period were included, with analysis of variables such as maternal age, prenatal care attendance, newborn age at notification, final case classification, and clinical outcome. Data were tabulated in Microsoft Excel and analyzed using absolute and relative frequencies. During the study period, 4,886 cases were reported, with a progressive increase until 2022 and a decrease in 2023. The incidence rate per 1,000 live births reached 10.0 in 2022, exceeding the WHO benchmark (<0.5). The distribution by sex was balanced, and 96.7% of cases were identified within the first six days of life. Most pregnant women underwent prenatal care (85.2%), but a significant proportion—particularly among those aged 10 to 29 years—did not receive adequate follow-up. Recent CS cases predominated, with 54 deaths directly attributed to the disease, in addition to stillbirths and miscarriages. These findings highlight weaknesses in prenatal care and epidemiological surveillance, indicating that reducing neonatal morbidity and mortality depends on early screening, qualified follow-up, and continuous monitoring of health indicators.
