Brazil has achieved a landmark public health milestone, becoming the most populous country in the Americas to eliminate mother-to-child transmission of HIV. The World Health Organization (WHO) validated the country’s success on December 18, 2025, a testament to its commitment to universal healthcare and the rights of mothers and children. This achievement represents a significant step forward in the global fight against HIV and offers a powerful example of what’s possible with sustained political will and equitable access to health services.
The validation signifies that Brazil has reduced vertical transmission of HIV – the passage of the virus from mother to child during pregnancy, childbirth, or breastfeeding – to below 2% and has achieved over 95% coverage for essential prenatal care, HIV testing, and timely treatment for pregnant women living with HIV. This success builds on decades of investment in Brazil’s Unified Health System (SUS), a publicly funded system that prioritizes primary healthcare and accessibility for all citizens. The elimination of mother-to-child transmission of HIV is a critical component of broader efforts to improve maternal and child health outcomes and reduce the overall burden of HIV in the country.
A Commitment to Universal Access
The milestone was formally recognized during a ceremony in Brasília, attended by key figures including President Luiz Inácio Lula da Silva, Brazil’s Minister of Health Alexandre Padilha, and Dr. Jarbas Barbosa, Director of the Pan American Health Organization (PAHO), alongside representatives from UNAIDS. The presence of these leaders underscores the national importance placed on this achievement and the ongoing commitment to public health initiatives. Dr. Tedros Adhanom Ghebreyesus, WHO Director-General, hailed the accomplishment as “a major public health achievement,” particularly given the scale and complexity of Brazil’s population and healthcare system. He emphasized that Brazil’s success demonstrates that every country can ensure children are born free of HIV and mothers receive the care they deserve with the right resources and dedication.
How Brazil Achieved Elimination
Brazil’s approach to eliminating mother-to-child transmission of HIV was progressive and strategically implemented. The country adopted a subnational strategy, initially certifying states and municipalities with populations exceeding 100,000 inhabitants. This phased approach allowed for adaptation of the PAHO/WHO validation methodology to the national context whereas maintaining consistency across the country. The evaluation process, supported by PAHO, involved independent experts who meticulously reviewed data, documentation, and health facility operations. Their findings were then assessed by the WHO’s Global Validation Advisory Committee, which ultimately recommended Brazil’s validation.
Beyond meeting the quantitative targets for transmission rates and coverage, Brazil demonstrated a commitment to delivering high-quality services for both mothers and infants. Robust data and laboratory systems were crucial in monitoring progress and identifying areas for improvement. Crucially, the country’s success is rooted in a strong commitment to human rights, gender equality, and community engagement, ensuring that all pregnant women have access to the care they need, regardless of their socioeconomic status or geographic location. Dr. Barbosa of PAHO highlighted that eliminating vertical transmission requires knowing HIV status, timely treatment, and access to maternal health services and safe delivery.
Part of a Regional and Global Effort
Brazil’s achievement is part of a broader regional initiative known as the EMTCT Plus Initiative, which aims to eliminate mother-to-child transmission of not only HIV but too syphilis, hepatitis B, and congenital Chagas disease. This initiative is a collaborative effort involving UNICEF and UNAIDS and is embedded within PAHO’s Elimination Initiative, a comprehensive regional effort to eliminate over 30 communicable diseases in the Americas by 2030. Over the past decade (2015-2024), this initiative has averted more than 50,000 pediatric HIV infections in the Region of the Americas.
Winnie Byanyima, UNAIDS Executive Director, expressed delight at Brazil’s certification, noting it is the first country with a population exceeding 100 million to achieve this milestone. Byanyima emphasized the key strategies employed by Brazil: prioritizing universal health care, addressing the social determinants of health, protecting human rights, and ensuring access to essential medicines. Globally, Brazil is now one of 19 countries and territories validated by the WHO for EMTCT, with twelve of those located in the Americas. Cuba was the first country worldwide to achieve this validation in 2015, followed by other nations including Anguilla, Antigua and Barbuda, and Dominica in subsequent years.
The success in Brazil and across the Americas demonstrates the feasibility of eliminating mother-to-child transmission of HIV. However, continued vigilance and investment are essential to sustain these gains and prevent resurgence. Ongoing monitoring, data collection, and adaptation of strategies will be crucial to address emerging challenges and ensure that all mothers and children have access to the care they need to thrive.
Looking ahead, Brazil will continue to strengthen its healthcare infrastructure and expand access to HIV prevention and treatment services. The country’s experience will serve as a valuable model for other nations striving to achieve similar milestones in the fight against HIV and improve the health of future generations. The focus will remain on maintaining high levels of coverage for prenatal care, HIV testing, and treatment, as well as addressing the social and economic factors that contribute to HIV vulnerability.
