INCIDENCE OF ACQUIRED SYPHILIS IN ADOLESCENTS IN THE STATE OF AMAZONAS: EPIDEMIOLOGICAL ANALYSIS IN THE PERIOD FROM 2014 TO 2024

Abstract

This article sought to analyze the incidence of syphilis acquired in adolescents aged 10 to 19 years in the state of Amazonas, in the period from 2014 to 2024. The work presents a quantitative research, with an epidemiological, descriptive and retrospective design, based on secondary data obtained from the Notification Disease Information System (SINAN). In the analyzed period, 3,378 cases of acquired syphilis were reported, 6.2% between 10 and 14 years and 93.8% between 15 and 19 years old, with a predominance of males (53.8%). Incidence rates grew from 16.9 per 100,000 inhabitants in 2014 to 64.2 in 2019, followed by a gradual decline until 2024 (13.3/100 thousand). The spatial analysis showed a strong urban concentration, especially in Manaus and regional health centers. These results indicate greater vulnerability among older adolescents and reinforce the influence of social and behavioral factors on the spread of the disease. It is concluded that acquired syphilis remains a relevant public health problem in Amazonas, requiring strengthening of prevention actions, early diagnosis, sex education and epidemiological surveillance aimed at the adolescent population.
