Congenital syphilis rates in the United States have reached levels of public health alarm, prompting urgent warnings from clinicians and former public health officials. Dr. Jeffrey D. Klausner, a physician and former public health administrator, has articulated deep concern about the trajectory of this preventable infection in newborns, signaling a critical gap in maternal screening and treatment protocols.
Key takeaways
- Congenital syphilis rates are rising sharply in the United States, driven by increases in maternal syphilis infections
- Early detection through prenatal screening and prompt antibiotic treatment can prevent nearly all cases of congenital syphilis
- Systemic barriers to prenatal care and incomplete treatment of pregnant women with syphilis are primary contributing factors
- Physicians and policymakers must prioritize integrated screening protocols and expanded access to treatment
Congenital Syphilis: A Preventable Crisis
Clinical interventions can eliminate transmission when implemented at scale

The Evidence Base: Why Screening Works
Penicillin, administered during pregnancy, has a documented cure rate exceeding 95% for maternal syphilis infections, according to guidelines from the U.S. Centers for Disease Control and Prevention (CDC). When prenatal screening is performed in the first trimester and treatment is completed before the third trimester, congenital transmission is virtually eliminated. This represents one of modern medicine’s most effective preventive interventions.
Dr. Klausner’s concern reflects the reality that current congenital syphilis cases represent a systems failure, not a limitation of available medical tools. The infection is neither new nor untreatable—it is preventable through established clinical protocols that have remained effective for decades. The rise in cases therefore signals inadequate implementation of proven preventive strategies across the healthcare system.
Barriers to Prevention: Access and Screening Coverage
The resurgence of congenital syphilis points to multiple systemic vulnerabilities in maternal healthcare delivery. Pregnant individuals in underserved communities often lack consistent access to prenatal care, delaying syphilis detection until late pregnancy or even delivery. Additionally, incomplete treatment—where pregnant women receive fewer than the recommended doses of penicillin—fails to achieve cure before fetal exposure.
Dr. Klausner’s experience as a former public health official underscores that the barrier is not scientific ignorance but rather resource allocation and care coordination. Expanding prenatal screening capacity, ensuring treatment completion, and integrating sexual partner notification into antenatal protocols are all proven interventions currently implemented inconsistently across U.S. health systems. The Health Policy landscape must address these implementation gaps as a matter of urgent public health priority.
Clinical Implications: What Frontline Providers Must Do
For clinicians, Dr. Klausner’s concern translates into concrete practice changes. All pregnant individuals should receive serological testing for syphilis at the first prenatal visit, and again in the third trimester, according to CDC prenatal screening guidelines. Providers must be vigilant for signs of active infection—such as rash, lymphadenopathy, or reactive serology—and initiate benzathine penicillin G immediately upon diagnosis. Partner notification and treatment are equally critical to prevent reinfection.
Maternal-fetal medicine specialists and obstetricians should view congenital syphilis cases not as unavoidable complications but as sentinel events indicating gaps in care delivery. Each case should trigger system-level audit and corrective action, consistent with the approach taken for other preventable adverse outcomes. This reflects the standards outlined in quality improvement frameworks emphasized across Quality & Safety guidance.
Congenital syphilis is 100% preventable with adequate prenatal screening and maternal antibiotic treatment—making current cases a reflection of healthcare system failures rather than clinical inevitability.

What this means
Frequently asked questions
Is congenital syphilis curable if the baby is already infected?
Yes. Newborns diagnosed with congenital syphilis respond well to penicillin treatment, achieving cure rates above 90% when initiated promptly. However, early treatment of the pregnant mother before delivery is vastly preferable, as it prevents infection altogether and avoids the need for neonatal treatment and potential long-term sequelae.
Why are congenital syphilis rates rising if we have effective prevention?
The rise reflects reduced prenatal screening capacity in some regions, gaps in treatment completion, and increases in maternal syphilis infections overall. This is not a problem of medical knowledge but rather inconsistent healthcare access and delivery—a systems issue rather than a scientific one.
What should pregnant individuals do if they are diagnosed with syphilis?
Seek immediate treatment with benzathine penicillin G from an obstetrician or infectious disease specialist. Treatment is safe in pregnancy and nearly 100% effective at preventing congenital transmission. Partner notification and treatment are equally important to prevent reinfection.
Dr. Klausner’s call for action reflects a fundamental truth: modern obstetric and public health systems possess all the tools needed to eliminate congenital syphilis. The physician’s alarm is justified not because the disease is inevitable, but because rising rates represent a preventable failure of healthcare delivery. The path forward requires sustained investment in prenatal screening infrastructure, treatment access, and clinical accountability—ensuring that every pregnant individual receives the evidence-based care that protects both mother and child.
