The Rising Tide of Congenital Syphilis: Why Prenatal Screening Lags and What’s Next
Despite legal mandates for comprehensive syphilis testing during pregnancy, a significant gap remains in ensuring expectant mothers receive the recommended screenings. New data presented at IDWeek 2025 reveals that fewer than one in five pregnant patients at a major North Carolina health system completed all three required tests. This shortfall is occurring amidst a national surge in congenital syphilis, raising critical questions about access to care and the effectiveness of current public health strategies.
Persistent Gaps in Screening: A Closer Look
Researchers at the University of North Carolina School of Medicine analyzed over 96,000 pregnancy episodes between 2019 and 2023. While 88.8% of pregnancies included at least one syphilis test, full compliance with the three-timepoint screening protocol – first prenatal visit, 28-30 weeks and delivery – was only 15.5%. The most significant drop-off occurred in the late second trimester, with only 24% of patients tested between 28 and 31 weeks.
These findings aren’t isolated. National data from the CDC shows a disturbing trend: nearly 4,000 cases of newborn syphilis were reported in 2024, marking the twelfth consecutive year of increase. This represents a nearly 700% rise since 2015, when just 495 cases were reported. While the rate of increase slowed slightly in 2024, the overall numbers remain alarmingly high.
Disparities in Access and Care
The UNC study similarly highlighted significant disparities in screening rates. Black women, patients insured through Medicaid, and those requiring language assistance were less likely to complete all three screening tests. This underscores the role of structural barriers in accessing consistent prenatal care and the need for targeted interventions to address inequities.
“This suggests a need for structural interventions to support access to care for all pregnant patients,” stated Dr. Stephanie Sweitzer, the presenting author of the UNC study.
The Call for Innovative Solutions
Experts are urging a shift towards more proactive and accessible screening methods. Jeffrey Klausner, MD, MPH, of USC Keck School of Medicine, emphasized the need for new strategies, including the implementation of rapid, point-of-care syphilis tests. These tests can deliver results in as little as 10 minutes, enabling immediate treatment and preventing transmission to the fetus.
Other proposed solutions include implementing standing orders in laboratory workflows to automatically include syphilis testing with routine prenatal blood panels, and increasing accountability from state and local health departments to ensure consistent screening practices.
Pro Tip: Healthcare providers should familiarize themselves with the latest syphilis screening guidelines and advocate for policies that streamline access to testing for all pregnant patients.
Future Trends and Potential Impacts
The congenital syphilis crisis is likely to continue unless significant changes are made to prenatal care practices. Several trends are expected to shape the future of this issue:
- Increased Adoption of Point-of-Care Testing: Rapid tests will turn into more widely available, particularly in underserved communities.
- Enhanced Data Tracking and Surveillance: Improved data collection and analysis will help identify areas with the greatest need and track the effectiveness of interventions.
- Expanded Public Health Initiatives: Increased funding for public health programs focused on syphilis prevention and treatment will be crucial.
- Telehealth Integration: Telehealth platforms can be used to provide remote counseling and support to pregnant patients, improving access to care.
FAQ: Congenital Syphilis and Prenatal Screening
Q: What is congenital syphilis?
A: Congenital syphilis is a serious infection passed from a mother to her baby during pregnancy. It can cause severe health problems, including stillbirth, premature birth, and lifelong disabilities.
Q: Why is prenatal syphilis screening important?
A: Early detection and treatment of syphilis during pregnancy can prevent congenital syphilis and protect the health of both mother and baby.
Q: What are the recommended syphilis screening times during pregnancy?
A: Screening is recommended at the first prenatal visit, again at 28-30 weeks, and at delivery.
Q: What can be done to improve syphilis screening rates?
A: Implementing rapid testing, streamlining laboratory workflows, and addressing social determinants of health are key strategies.
Did you realize? Syphilis is a curable infection. Early treatment with antibiotics can prevent congenital syphilis in almost all cases.
This ongoing crisis demands a multifaceted approach, combining improved screening practices, targeted interventions for vulnerable populations, and a renewed commitment to public health. The health of future generations depends on it.
