Abstract
Abstract: This study aimed to describe the epidemiological profile of cases of congenital syphilis in the state of Maranhão from 2014 to 2018. This is an epidemiological study of quantitative approach, descriptive and exploratory, with data collection performed at the Platform of the Informatics Department of the Unified Health System (DATASUS). It was observed that Maranhão had the highest index in the year 2018, corresponding to 34.6%. Although 84.1% of pregnant women underwent prenatal care and 47.2% were diagnosed during prenatal care, 67.8% 9 underwent treatment inappropriately and 12.92% did not receive it. It was pertinent with regard to the treatment of the partner, where 54.9% did not perform it, thus contributing to the percentage of 96.7% cases of recent congenital syphilis. Therefore, the study showed the high incidence of CS in Maranhão, and this is related to several factors, especially the non-treatment of the partner and consequently the mother's reinfection and fetal infection.
