Brazil has been officially recognised by the World Health Organization (WHO) for eliminating the vertical transmission of HIV — the route through which the virus is passed from mother to child during pregnancy, childbirth or breastfeeding. The certification was formally presented in Brazil to President Luiz Inácio Lula da Silva and the country’s Minister of Health, Alexandre Padilha, marking a major milestone in national and global public health.
With this recognition, Brazil becomes part of a select group of nineteen countries and territories worldwide that have achieved this standard. Importantly, Brazil is the first nation with a population exceeding 100 million people to reach this level of control, highlighting the scale and robustness of its public health response.
Public health indicators behind the certification
According to criteria established by the WHO, certification requires sustained evidence that vertical HIV transmission rates remain below 2%, alongside strong health system performance. In Brazil’s case, the achievement was supported by prenatal care coverage exceeding 95%, routine HIV testing for pregnant women, and timely initiation of antiretroviral therapy when infection is detected.
Since 1996, Brazil’s Unified Health System (Sistema Único de Saúde – SUS) has provided free and universal access to antiretroviral treatment, a policy widely cited in scientific literature as a cornerstone of the country’s HIV response. Studies published in international medical journals have consistently shown that early diagnosis combined with appropriate treatment can reduce the risk of mother-to-child transmission to near zero.
Clinical practice and prevention strategies
Infectious disease specialists emphasise that eliminating vertical transmission is the result of coordinated clinical interventions rather than a single measure. Regular antenatal follow-up, early HIV screening, correct use of antiretroviral therapy, safe delivery practices and structured monitoring of newborns are all essential components.
These strategies are aligned with WHO guidelines, which stress the importance of integrating HIV care into routine maternal and child health services. Evidence from longitudinal studies confirms that countries adopting comprehensive prenatal testing and treatment programmes achieve the most significant reductions in paediatric HIV infections.
Broader impact on HIV outcomes in Brazil
The certification comes amid broader improvements in HIV-related indicators in Brazil. Data from the Ministry of Health show that AIDS-related mortality has fallen to its lowest level since records began, currently standing at 3.4 deaths per 100,000 inhabitants. Since the start of the epidemic in the early 1980s, over 1.16 million people have been diagnosed with HIV in the country, while approximately 402,300 deaths have been attributed to AIDS-related causes over the past four and a half decades.
Cuba was the first country globally to receive WHO certification for eliminating vertical HIV transmission in 2015. Brazil’s inclusion in this group reflects both the maturity of its healthcare infrastructure and the long-term impact of sustained public investment in prevention, diagnosis and treatment.
A milestone for health policy
Health professionals and policymakers in Brazil have framed the WHO recognition as evidence of the effectiveness of public health funding and coordinated national strategies. Beyond its symbolic value, the certification underscores how large and diverse countries can achieve ambitious health targets when universal access and evidence-based care are prioritised.
As global health authorities continue to push towards the elimination of paediatric HIV worldwide, Brazil’s experience is increasingly viewed as a reference point for other nations seeking to reduce inequalities in access to maternal and child healthcare.
