Abstract
Objective: To analyze the temporal trend of acquired syphilis incidence in the municipality of Ponta Grossa, Paraná, between 2010 and 2024, considering stratification by sex and age group. Methods: This is a basic, ecological, and longitudinal study with a quantitative-qualitative approach. Secondary data were obtained from the Notifiable Diseases Information System (SINAN), stratified by sex and age group. Results: A marked increase in reported cases was identified starting in 2015, peaking in 2022 (808 cases), followed by a slight decrease in 2023 and a sharp decline in 2024 (partial data). The highest incidence was found among men—especially from 2021 onwards—and in individuals aged 20 to 39 years. Conclusion: The findings highlight the need for intersectoral strategies focused on expanding testing, sexual education, and addressing social vulnerabilities, particularly among adolescents and young adults, to control acquired syphilis in the context of Primary Health Care.
