Denmark Eliminates Mother-to-Child Transmission of HIV & Syphilis: WHO Validation

Denmark has achieved a landmark public health milestone, becoming the first country in the European Union to eliminate mother-to-child transmission (EMTCT) of both HIV and syphilis. The World Health Organization (WHO) certified the country’s success, recognizing decades of sustained commitment to ensuring every child is born free from these infections. This achievement underscores the power of robust public health systems, consistent investment in maternal and child health services, and a dedication to equitable access to care.

The validation, confirmed by both the WHO’s Regional Validation Committee in June 2025 and the Global Validation Advisory Committee (GVAC) in August 2025, demonstrates that Denmark consistently met stringent targets between 2021 and 2024. These included maintaining low transmission rates and achieving high coverage of prenatal testing and treatment for pregnant women. Specifically, elimination, as defined by the WHO, requires testing and treating at least 95 out of every 100 pregnant women and keeping new infant infections below 50 per 100,000 births annually.

A Model for Europe and Beyond

“The elimination of mother-to-child transmission of HIV and syphilis marks a major public health achievement for Denmark,” stated Dr. Tedros Adhanom Ghebreyesus, WHO Director-General. Dr. Hans Henri P. Kluge, WHO Regional Director for Europe, added that Denmark’s success serves as a “testament to the strength of its maternal health system and its long-standing commitment to reaching every pregnant woman with the care she needs.” Denmark now joins 22 other countries and territories globally that have been validated by the WHO for eliminating these infections from mother to child, including nations in the Americas, Asia, and Africa. The WHO press release details the full list of validated countries.

Understanding Mother-to-Child Transmission

Mother-to-child transmission, also known as vertical transmission, occurs when an infected mother passes a pathogen to her baby during pregnancy, childbirth, or breastfeeding. Both HIV and syphilis can have devastating consequences for infants, including severe illness, disability, and even death. Syphilis, if untreated, can lead to stillbirth, neonatal death, or congenital syphilis in newborns. HIV weakens the immune system, leaving infants vulnerable to opportunistic infections.

Eliminating EMTCT isn’t simply about treating infected mothers; it’s about a comprehensive approach to healthcare. This includes widespread prenatal screening to identify infections early, providing antiretroviral therapy (ART) for HIV-positive mothers, and administering appropriate treatment for syphilis during pregnancy. Effective antenatal care, reliable data systems, and a commitment to women’s rights are also crucial components.

Denmark’s Key Strategies for Success

Denmark’s achievement is rooted in several key factors. The country’s universal health system, built on equal access for all citizens, ensures that all pregnant women have access to the necessary screening and care, regardless of socioeconomic status or geographic location. Sophie Løhde, Denmark’s Minister for the Interior and Health, emphasized that this universal access was “the foundation of this achievement.”

Beyond universal access, Denmark’s success is also attributable to its exemplary data systems, robust laboratory capacity, and high human rights standards. These elements allow for effective surveillance, rapid response to outbreaks, and the ability to monitor progress towards elimination goals. The country’s commitment to integrated screening during pregnancy, combining tests for multiple infections, further streamlines the process and ensures comprehensive care.

Current Infection Rates in Denmark

Data from the WHO indicates that approximately 5950 people are currently living with HIV in Denmark, with less than 0.1% of pregnant women affected. Routine testing and treatment programs have effectively reduced mother-to-child transmission of HIV to zero. For syphilis, the prevalence of congenital syphilis is also uncommon due to systematic prenatal screening and care. In 2024, 626 cases of syphilis were reported with the majority (524) occurring in men and a smaller number (102) in women. These low infection rates highlight the effectiveness of Denmark’s public health efforts.

Looking Ahead: Towards Triple Elimination

While Denmark has successfully eliminated EMTCT of HIV and syphilis, the country is now setting its sights on achieving “triple elimination” – adding hepatitis B virus to the list of infections prevented from being passed from mother to child. The WHO is actively working with Denmark to advance this process, recognizing the potential for further improving maternal and child health outcomes. Denmark’s experience provides a valuable model for other countries seeking to strengthen their EMTCT programs and perform towards triple elimination.

The Importance of Continued Surveillance and Data Collection

Elimination doesn’t mean the end of vigilance. Continued surveillance and data collection are essential to monitor for any resurgence of transmission and to ensure that the gains made are sustained. Robust data systems allow public health officials to identify potential outbreaks early and implement targeted interventions. Ongoing research is needed to improve screening and treatment strategies and to address emerging challenges.

The WHO emphasizes that Denmark’s success demonstrates what is possible when rights-based policies, high-quality services, and strong data systems converge. This achievement serves as a powerful motivator for other countries to prioritize maternal and child health and invest in the infrastructure needed to eliminate these preventable infections.
