The World Health Organization (WHO) has officially validated Brazil for eliminating mother-to-child transmission of HIV, making it the most populous country in the Americas to achieve this landmark public health milestone.
Universal healthcare drives success
WHO said Brazil’s achievement reflects decades of sustained political commitment to universal and free healthcare through its Unified Health System (SUS). Anchored in strong primary healthcare, the system ensured early diagnosis, timely treatment, and continuity of care for pregnant women living with HIV, while upholding human rights and gender equity.
“Eliminating mother-to-child transmission of HIV is a major public health achievement, especially for a country as large and complex as Brazil,” said WHO Director-General Tedros Adhanom Ghebreyesus. He added that Brazil’s model demonstrates how equitable access to quality healthcare can ensure every child is born free of HIV.
Meeting strict WHO criteria
Brazil met all WHO validation benchmarks, including reducing vertical HIV transmission to below 2% and achieving more than 95% coverage in prenatal care, HIV testing, and treatment for pregnant women. The country also demonstrated strong laboratory systems, reliable data monitoring, and quality care for both mothers and infants.
A phased, subnational strategy played a key role, with large states and municipalities certified first, while maintaining national consistency in standards and delivery.
Independent evaluation and regional support
The validation process was supported by the Pan American Health Organization (PAHO) and conducted by independent experts who assessed health facilities, documentation, and surveillance systems. The findings were reviewed by WHO’s Global Validation Advisory Committee, which formally recommended Brazil’s certification.
PAHO Director Jarbas Barbosa said the success was driven by health workers and civil society groups who ensured vulnerable populations were not left behind.
Part of a wider elimination effort
Brazil’s success is part of the EMTCT Plus Initiative, aimed at eliminating mother-to-child transmission of HIV, syphilis, hepatitis B, and congenital Chagas disease, in partnership with UNAIDS and UNICEF. Over the past decade, more than 50,000 paediatric HIV infections have been prevented across the Americas.
UNAIDS Executive Director Winnie Byanyima praised Brazil’s approach, highlighting its focus on universal healthcare, addressing social determinants, and protecting human rights.
Global recognition
Brazil now joins 18 other countries worldwide validated by WHO for eliminating mother-to-child HIV transmission, reinforcing the message that ending vertical transmission is achievable with sustained commitment and inclusive health systems.
