Countries race to end mother-to-child transmission of HIV and syphilis

Countries race to end mother-to-child transmission of HIV and syphilis

New Capabilities

Denmark becomes the first European Union nation validated by the World Health Organization, joining a growing list of 23 countries

February 27th, 2026: Denmark becomes first EU country validated for EMTCT

Overview

Every year, roughly 120,000 children worldwide are born with HIV they could have avoided. Denmark just proved that number can be zero.

On February 27, 2026, the World Health Organization validated Denmark as the first European Union country to eliminate mother-to-child transmission of both HIV and syphilis. Routine prenatal screening and treatment achieved zero new mother-to-child transmissions across four consecutive years.

Denmark is the twenty-third country or territory to earn the designation since Cuba became the first in 2015. The milestone arrives amid sharp divergence: validated nations expand the list while the United States reported nearly 4,000 congenital syphilis cases in 2024, a 700% increase over the decade. The gap between countries that have built universal screening into prenatal care and those that haven't is widening fast.

  1. Denmark becomes first EU country validated for EMTCT

    Latest Milestone

    WHO formally announces that Denmark has eliminated mother-to-child transmission of HIV and syphilis, making it the first European Union member state and twenty-third country or territory globally to achieve the certification.

  2. Brazil validated as largest country to achieve EMTCT of HIV

    Milestone

    WHO validates Brazil for elimination of mother-to-child HIV transmission, making it the most populous country and first nation of over 100 million people to earn the certification.

  3. Maldives achieves world's first Triple Elimination

    Milestone

    The Maldives becomes the first country to achieve elimination of mother-to-child transmission of all three diseases: HIV, syphilis, and hepatitis B.

  4. Global committee confirms Denmark meets all targets

    Assessment

    WHO's Global Validation Advisory Committee confirms Denmark has met all required criteria for EMTCT elimination, including transmission rates, screening coverage, and human rights standards.

  5. WHO Regional Committee reviews Denmark's data

    Assessment

    WHO's Regional Validation Committee for Europe assesses Denmark's data on prenatal screening coverage, treatment rates, and transmission outcomes from 2021 to 2024.

  6. World Health Assembly endorses Triple Elimination strategy

    Policy

    The World Health Assembly expands the elimination goal to include hepatitis B alongside HIV and syphilis, creating the Triple Elimination Initiative targeting all three infections by 2030.

  7. Thailand validated as first in Asia

    Milestone

    Thailand becomes the first country in Asia to receive WHO validation for EMTCT of HIV and syphilis, and the first with a large HIV epidemic to achieve elimination.

  8. Cuba becomes first country validated for EMTCT

    Milestone

    WHO validates Cuba as the first country in the world to eliminate mother-to-child transmission of both HIV and syphilis, proving nationwide elimination is achievable.

  9. WHO launches Global Plan to end child HIV infections

    Policy

    The Joint United Nations Programme on HIV/AIDS and the World Health Organization launch the Global Plan towards elimination of new HIV infections among children by 2015, setting the framework for country-by-country validation.

Historical Context

3 moments from history that rhyme with this story — and how they unfolded.

June 2015

Cuba's EMTCT validation (2015)

Cuba became the first country in the world to receive WHO validation for eliminating mother-to-child transmission of both HIV and syphilis. An international expert mission visited Cuba in March 2015 and confirmed that in 2013, only two babies were born with HIV and five with congenital syphilis in the entire country. Cuba achieved this through universal prenatal care, partner testing, treatment, cesarean deliveries, and breastfeeding substitution for HIV-positive mothers.

Then

The validation proved that nationwide elimination of mother-to-child transmission was achievable, not just a theoretical target. It created the template other countries would follow.

Now

Cuba's success launched a wave of validations, particularly in the Caribbean and small island nations, and prompted WHO to expand the initiative to include hepatitis B and create the Triple Elimination framework.

Why this matters now

Cuba demonstrated the proof of concept that Denmark and 21 other countries have now replicated. The core mechanism is the same: universal screening early in pregnancy, immediate treatment, and follow-through at delivery. Denmark's achievement extends this model into the European Union for the first time.

June 2016

Thailand's EMTCT validation (2016)

Thailand became the first country in Asia and the first with a large HIV epidemic to achieve WHO validation. In 2000, an estimated 1,000 Thai children were infected with HIV through mother-to-child transmission annually. By 2015, that number had fallen to 85, with 98% of pregnant women living with HIV receiving antiretroviral therapy.

Then

Thailand's validation showed that countries with significant HIV burdens, not just low-prevalence nations, could achieve elimination through systematic screening and treatment.

Now

Thailand's success encouraged higher-burden countries in Africa and South America to pursue validation, leading to Botswana, Namibia, and eventually Brazil joining the list.

Why this matters now

Thailand proved that elimination is not limited to small or low-burden countries. Denmark's case adds another dimension: it shows that wealthy EU nations with strong healthcare systems, which might have assumed the problem was already solved informally, benefit from the rigor of formal WHO validation.

May 1980

Global smallpox eradication certified (1980)

The World Health Assembly formally declared smallpox eradicated on May 8, 1980, three years after the last naturally occurring case was found in Ali Maow Maalin, a hospital cook in Merca, Somalia, in October 1977. A Global Commission of scientists from 19 nations certified the eradication in December 1979 after intensive country-by-country verification.

Then

Routine smallpox vaccination ceased worldwide, saving billions of dollars annually and ending a disease that had killed an estimated 300 million people in the twentieth century alone.

Now

Smallpox remains the only human disease ever fully eradicated. It established the model of independent expert commissions verifying country-by-country elimination that WHO now uses for the EMTCT initiative.

Why this matters now

WHO's EMTCT validation process directly descends from the smallpox eradication verification model: independent expert committees, standardized criteria, and country-by-country certification. The difference is that EMTCT elimination must be continuously maintained rather than achieved once, making each validation an ongoing commitment rather than a permanent victory.
