Abstract The increased incidence of syphilis in Brazil can be explained by multiple reasons: increased reports of acquired syphilis, increased coverage of rapid tests in pregnant women provided by the Brazilian Ministry of Health, reduced condom use, inadequate treatment of patients and partners. In Ferraz de Vasconcelos, a city in the metropolitan region of São Paulo, an increasing elevation in syphilis cases in healthcare services and in the epidemiological surveillance system. In 2017, the city reported 148 cases from which 27 cases were congenital syphilis, with one death. The purpose of the survey was to evaluate the cases reported and describe the main sociodemographic, epidemiological, clinical, and syphilis investigation. A high incidence of syphilis in adults, pregnant women, and congenital syphilis was recorded with a detection rate of 45.0 per 100,000 in habitants and 12.4 and 9.3 per 1,000 live births, respectively. These rates reflect failures in the diagnosis, treatment, and follow-up of cases. Syphilis in adults was obtained in this study in a higher incidence in men 54.1%.Being 49.4% between brown and black people. It is noteworthy that more than 97% of the pregnant women reported with syphilis underwent prenatal care; however, 36.1% of them started from the second trimester, only 88.9% were given treatment, and 66.7% with record of healing. In addition, only in 27.8% pregnant women, the sexual partner underwent the specific treatment. Regarding congenital syphilis, only 81.5% newborns were given proper treatment and only 55.6% underwent laboratory investigation of cerebrospinal fluid. It is evident that these results expose the weaknesses of the municipal healthcare system. Greater coordination among services can contribute to early diagnosis and active search of cases. The epidemiological bulletin containing data from this study may enhance the organization of syphilis prevention, planning, and surveillance actions in the city. Key messages The increased incidence of syphilis in Brazil can be explained by multiple reasons: increased coverage of rapid tests on people, reduced condom use, inadequate treatment of patients and partners. Greater coordination among services can contribute to early diagnosis and active search of cases.
