This article sought to assess the prevalence of Syphilis Acquired in Brazilian territory from 2010 to June 2019. A cross-sectional, observational, retrospective and analytical and quantitative study was carried out, based on data collection from the Health Information System of Notification (SINAN) of the Ministry of Health from 2010 to June 2019. There was an increase in cases of Acquired Syphilis in Brazil, with the highest incidence rate in the Southeast and the lowest in the North. It was noticed that the profile of people affected by Acquired Syphilis, in Brazil, in the same time interval, was male, with 59.6%; aged 20 to 29 years, 33.6%; illiterate (1.2%), with incomplete primary education (1st to 4th incomplete (5.8%), 4th complete (3.6%) and 5th to 8th incomplete (12.1%)) and complete (7.9 %); and white (37.8%), brown (34.2%) and black (9.7%). The study of acquired syphilis rates is a valuable tool for public health, enabling prevention and control planning according to epidemiology, encouraging adherence to treatment and its follow-up.
