Recently, Denmark was certified by the World Health Organization as the first country in the European Union to eliminate mother-to-child transmission (MTCT) of both HIV and Syphilis. This achievement represents a major public health success and demonstrates the effectiveness of strong maternal healthcare systems, universal testing, and timely treatment interventions.

What is Mother-to-Child Transmission (MTCT)?

Mother-to-Child Transmission (MTCT), also known as vertical transmission, refers to the spread of certain infections from a pregnant woman to her baby during pregnancy, childbirth and breastfeeding.

Without timely intervention, infections such as HIV and syphilis can lead to serious consequences including:

• Infant HIV infection
• Congenital syphilis
• Stillbirths and neonatal deaths
• Severe lifelong health complications

Therefore, preventing MTCT is a major priority in global maternal and child health programmes.

WHO Criteria for Elimination of MTCT

The WHO defines elimination of mother-to-child transmission through strict epidemiological and health system indicators. A country must achieve:

• Transmission rates below 50 cases per 100,000 live births, and
• More than 95% coverage of testing and treatment among pregnant women

These benchmarks ensure that both detection and treatment systems are robust enough to prevent transmission to newborns.

Global Context of EMTCT

Denmark joins a growing group of countries validated by the WHO for eliminating MTCT or making significant progress toward this goal. More than 20 countries and territories worldwide have achieved or are nearing this milestone.

Examples include:

• Caribbean nations such as Anguilla and Antigua and Barbuda
• South American countries such as Brazil
• African countries such as Botswana
• Asian nations including Malaysia and Maldives

These achievements demonstrate that elimination is possible across different health systems when strong policies and universal maternal healthcare are implemented.

WHO’s Triple Elimination Strategy

To address maternal transmission of infectious diseases, WHO promotes a Triple Elimination Strategy targeting: HIV, Syphilis, and Hepatitis B

The strategy is built on four key pillars:

• Universal access to antenatal care
• Integrated testing for maternal infections
• Effective treatment and prevention protocols
• Strong health systems supported by community engagement and human-rights protections

This integrated approach helps ensure that maternal health services detect infections early and prevent transmission to infants.

Understanding the Diseases

HIV (Human Immunodeficiency Virus)

• HIV attacks the body’s immune system, particularly CD4 cells, weakening the body’s ability to fight infections.
• If untreated, HIV can progress to Acquired Immunodeficiency Syndrome (AIDS), making individuals vulnerable to life-threatening infections and cancers.

Syphilis

• Syphilis is a sexually transmitted bacterial infection caused by Treponema pallidum. The disease progresses through stages that may include painless sores, skin rashes, and severe complications affecting the heart, brain, and nervous system if left untreated. Congenital syphilis can cause severe health problems in newborns.

Significance of Denmark’s Achievement

Denmark’s certification highlights several important aspects of effective public health policy:

• Strong maternal healthcare and antenatal screening systems
• Universal testing and treatment for pregnant women
• Integration of infectious disease control with maternal health services
• Sustained public health surveillance and policy commitment

This milestone also reinforces the feasibility of eliminating vertical transmission of infectious diseases through coordinated healthcare strategies.
