Abstract
BACKGROUND: Congenital syphilis remains a public health issue in Mexico. Timely screening during pregnancy is key to its prevention. OBJECTIVE: To evaluate the implementation of the dual HIV/Syphilis rapid test in pregnant women at the General Zone Hospital with Family Medicine No. 2 and its feasibility to meet the national goal of performing three tests per pregnancy. METHODS: A total of 8672 tests (2020 - 2024) were analyzed using MATLAB to identify trends by age, trimester, and test number. Linear regressions were applied, using the root mean square error as a measure of confidence, to project the fulfillment of the goal. RESULTS: Most pregnant women (74%) underwent only one test, mainly in the first trimester. An increase in second and third tests was observed in 2024. Projections suggest the goal may be reached between 2029 and 2030. CONCLUSIONS: The dual HIV/Syphilis screening strategy at this hospital shows significant progress toward universal testing during pregnancy. The trend suggests comprehensive care for all pregnant women, contributing to the reduction of congenital syphilis and improved maternal-neonatal health. Strengthening early detection, follow-up, and sexual health education remains essential.
