Advocating Against HIV Stigma: Gareth Thomas and Welton Gabriel’s Efforts in Brazil

Gareth Thomas, a retired rugby star from Wales and an HIV-positive advocate, arrived at Rio de Janeiro’s Ipanema Beach as part of the ‘Tackle HIV’ campaign. Known globally since revealing his HIV-positive status in 2019, Thomas aims to spread awareness about living with HIV.

This initiative resonated with Welton Gabriel, a 36-year-old from Sao Paolo, who also faced discrimination after revealing his positive status over a decade ago. When Gabriel informed his friends about being HIV positive, many distanced themselves. Gabriel, now an activist, appeared at the International AIDS Conference in Rio de Janeiro this summer, finding solidarity with Thomas in advocating against HIV stigma.

Gabriel’s journey involved battling a treatment-resistant strain of HIV, initially causing severe health issues. Fortunately, a change in medication stabilized his condition. However, societal discrimination remains challenging for him, mirroring Brazil’s broader issues regarding HIV stigma. Despite free access to medications through Brazil’s healthcare system, UNAIDS Brazil indicates over half of the HIV-positive individuals have faced discrimination, affecting personal relationships and work opportunities.

“People are still afraid of those three letters,” Gareth Thomas remarked, addressing the persistent stigma surrounding HIV.

As Gabriel collaborates with organizations like Barong, which provide mobile testing and education, he emphasizes the fear-driven discrimination stemming from a lack of awareness. He notes that despite medical advancements highlighted at the AIDS 2026 conference, HIV perceptions in Brazil resemble those from past decades, as seen during the iconic Brazilian singer Cazuza’s AIDS-related death in 1990.

The ‘Tackle HIV’ event at Ipanema Beach aimed to educate and shift public attitudes, focusing on teenagers from disadvantaged communities. Thomas stresses the importance of informing people about modern HIV treatments, noting misconceptions contribute to preventable deaths. Brazil’s national statistics reveal delayed diagnosis and treatment often result in advanced AIDS stages, leading to severe health declines.

Despite progress, Brazil still faces hurdles in achieving the U.N.’s treatment target, as only 82% of HIV-positive individuals access antiretroviral drugs. This shortfall impacts efforts to eradicate AIDS as a public-health threat. Gabriel identifies pervasive stigma within healthcare as a deterrent, discouraging individuals from maintaining medication adherence.

The legislative landscape in Brazil displays persistent challenges, with numerous proposals aiming to restrict sex and gender education in schools. High violence rates against sexual minorities exacerbate HIV-related discrimination, emphasizing societal stigmas attached to HIV, as observed by Beatriz Grinsztejn, an infectious-diseases specialist.

Gender-skewed discrimination is also prominent, according to activist Fabiana de Oliveira from the National Network of Women Living with HIV. De Oliveira shares her personal experience of stigma post-HIV diagnosis, illustrating societal pressures and emotional burdens faced by women in Brazil. Her narrative underscores the urgent need for broader education and openness in addressing HIV’s societal impact.

The irony lies in Brazil’s leading role in innovations like Lenacapavir, a groundbreaking drug blocking HIV transmission. Although clinical trials show effectiveness, De Oliveira remains skeptical about its success without comprehensive outreach and societal acceptance of HIV discussions.

Gabriel’s personal narrative highlights transformation through education. After disclosing his status and enlightening his family and friends, misconceptions were gradually dispelled, changing their perspectives on HIV.
