Estimation of the Incidence of Congenital Syphilis in Mexico Between 2019 and 2023

Introduction Congenital Syphilis (CS) is considered the second leading cause of preventable death in developing countries. The last report of the incidence rate of CS was made in 2017. Objective The objective of the study was to estimate the incidence of CS between 2019-2023. Materials and methods This is a retrospective study for which data were obtained from the new cases of CS reported in the Epidemiological Bulletin for 2019-2023 and from the newborn population records reported in the National Institute of Statistics and Geography and the National Population Council. Results In Mexico, the incidence rate of CS is 3.20 per 10,000 births. An increment of CS cases was observed between 2019-2023, with a higher number of cases in 2022. Conclusion A democratization of detection and prompt management is needed to reduce transmission, particularly among the most vulnerable population.
