O presente estudo tem como objetivo analisar o perfil epidemiológico da SC no estado do Rio de Janeiro no período de 2010 a 2022. Trata-se de um estudo ecológico retrospectivo que utilizou dados públicos do Sistema de Informações de Agravos de Notificação (SINAN), do Sistema de Informações sobre Nascidos Vivos (SINASC) e do IBGE. Foram analisados os casos confirmados de sífilis congênita, no período de 2010 a 2022, de acordo com o ano de notificação, com a microrregião IBGE de notificação, com a escolaridade materna, com a faixa etária materna, com o tratamento dos parceiros e segundo a classificação final de aborto/natimorto por sífilis. Calculou-se a prevalência de sífilis congênita a cada 100 habitantes das microrregiões do IBGE. Além disso, foram calculadas a incidência de sífilis na gravidez na adolescência e a taxa de letalidade da SC. Durante o período analisado houve 45.875 casos confirmados de sífilis congênita no estado do Rio de Janeiro. A microrregião do IBGE com maior prevalência foi o Rio de Janeiro (0,33 casos/ 100 habitantes). Ademais, foi possível observar que 27% dos casos são de mães que possuem como nível de escolaridade o ensino fundamental incompleto e apenas 0,45% das mulheres possuíam nível superior completo. A análise do tratamento dos parceiros de mulheres com diagnóstico confirmado mostrou que somente 10% realizaram o tratamento para sífilis. Além disso, notou-se que a incidência de SC dentre as gravidezes na adolescência no estado foi de 2,62 casos/ 100 gravidezes de jovens de 10 a 19 anos e dentre os casos de SC confirmados, 25,52% eram mães nesta faixa etária.
