Being right isn't enough if you haven't built trust
For nearly four decades, Brazilian physician Fábio Mesquita has moved through the world's most contested intersections — between science and faith, between public health and human dignity — building programs where none existed and finding common ground where division seemed absolute. His career, from pioneering Brazil's first municipal AIDS program in Santos to navigating the cultural complexities of Southeast Asia and Africa, offers a quiet argument that epidemics are never only biological events. In a recent interview and through his new book, Diário de Bordo, Mesquita reflects on what it means to protect human life not by demanding that people become different, but by meeting them as they are.
- When AIDS was still a death sentence and stigma ran deeper than science, Mesquita arrived in Santos and built something Brazil had never seen — a municipal AIDS program grounded in harm reduction and human acceptance.
- The strategies he championed faced fierce resistance from religious conservatives and public health traditionalists alike, creating a sustained tension between moral conviction and epidemiological urgency.
- His international work across Indonesia, the Philippines, Vietnam, and Portuguese-speaking Africa forced him to repeatedly ask the hardest question in global health: how do you save lives without erasing the worlds people actually inhabit?
- Over time, as evidence accumulated and preventable deaths became unacceptable, harm reduction shifted from radical provocation to recognized cornerstone — not because minds changed about drugs, but because survival became the shared priority.
- The unresolved tension between public health, human rights, and religious conservatism remains, but Mesquita argues that the progress achieved came from the courage to sit across from disagreement and find the common ground of human survival.
Fábio Mesquita sat down with journalist Cristina Angelini at Canal Angelini carrying nearly forty years of work behind him — work that had moved from the beaches of Santos to health ministries across three continents. The conversation traced a career spent building bridges between science and faith, between public health and human dignity, between what was politically possible and what was morally necessary.
In the epidemic's early years, when fear ran deeper than understanding, Mesquita helped establish Brazil's first municipal AIDS program in Santos. Its foundation was harm reduction — the radical notion that meeting people where they were, rather than where you wished them to be, might actually save their lives. The program became a model, rippling outward as proof that prevention and acceptance could coexist.
The work was never purely technical. Mesquita found himself in rooms with religious leaders, arguing that distributing condoms was not a moral failing but a moral imperative. His recently published book, Diário de Bordo, documents these friction points — moments where public health policy met deeply held belief, and where listening mattered as much as expertise.
International assignments took him to Indonesia, the Philippines, Vietnam, and Portuguese-speaking Africa, each place presenting its own tangle of cultural and religious complexity. The fundamental question remained constant: how do you protect people's lives while respecting the world they actually live in? There were no universal answers, only the hard work of dialogue.
Harm reduction faced fierce resistance before the evidence made its value undeniable. What had seemed like capitulation became recognized as one of the most powerful tools in HIV prevention — not because anyone changed their minds about drugs, but because watching preventable deaths became unacceptable.
The tension between public health, human rights, and religious conservatism never fully resolved, Mesquita acknowledged. But the progress made came not from one side defeating the other, but from the courage to find the common ground of human survival. The response to HIV, he concluded, was never only about virology. It was about solidarity, about fighting stigma, and about trusting that wisdom lives in many places.
Fábio Mesquita sat down in front of the camera at Canal Angelini with nearly four decades of work behind him—work that had taken him from the beaches of Santos to the corridors of health ministries across three continents. The conversation with journalist Cristina Angelini traced the arc of a career spent building bridges where others saw only walls: between science and faith, between public health and human dignity, between what was politically possible and what was morally necessary.
In the early years of the epidemic, when AIDS was still a death sentence and fear ran deeper than understanding, Mesquita arrived in Santos and helped establish something that had never existed in Brazil before—a municipal AIDS program built on principles that seemed radical at the time. Prevention, yes, but also acceptance. Harm reduction. The radical notion that meeting people where they were, rather than where you wished them to be, might actually save their lives. The program became a model, a proof of concept that would ripple outward.
But the work was never purely technical. Mesquita found himself in rooms with religious leaders, trying to explain why distributing condoms was not a moral failing but a moral imperative. These conversations, he reflected during the interview, were not obstacles to overcome but essential parts of the solution. The book he had recently published, Diário de Bordo, documented these moments—the friction points where public health policy met deeply held beliefs, and where listening mattered as much as expertise.
His international assignments took him to Indonesia, the Philippines, Vietnam, and into the Portuguese-speaking countries of Africa. Each place presented its own tangle of cultural, political, and religious complexity. Each required him to ask the same fundamental question: How do you protect people's lives while respecting the world they actually live in? There were no universal answers, only the hard work of dialogue and the willingness to be changed by what you learned.
Harm reduction—the strategy of reducing the harms associated with drug use rather than demanding abstinence as a precondition for care—had faced fierce resistance when Mesquita championed it. Religious conservatives saw it as capitulation. Public health traditionalists saw it as lowering standards. But over time, as the evidence accumulated and as people who might otherwise have died began to live, the strategy became recognized as one of the most powerful tools in the HIV prevention arsenal. What had seemed impossible became inevitable, not because anyone changed their minds about drugs, but because the alternative—watching preventable deaths—became unacceptable.
The tension between public health, human rights, and religious conservatism never fully resolved itself, Mesquita acknowledged. But the progress that had been made—and it was substantial—came not from one side defeating the other, but from the courage to sit across from people you disagreed with and find the common ground of human survival. It required political will. It required compassion. It required the understanding that science alone, however brilliant, could not answer the question of how to live together.
The book and the interview both pointed toward the same conclusion: the response to HIV had never been only about virology or epidemiology. It was about solidarity. It was about the unglamorous work of fighting stigma, defending the rights of the most marginalized, and building the kind of society where a diagnosis did not mean abandonment. It was about listening to voices that seemed far removed from the laboratory, and trusting that wisdom lived in many places.

La Conversación del Hearth Otra perspectiva de la historia
When you talk about dialogue between science and faith, what does that actually look like in practice? Are you asking religious leaders to accept scientific findings, or something else?
It's not about one side winning. In Santos, I wasn't trying to convince priests that condoms were theologically sound. I was asking them to help me think about how to keep people alive. Once you frame it that way—not as a clash of worldviews but as a shared problem—the conversation changes.
But there must have been moments where the two genuinely conflicted. Where science said one thing and faith said another.
Of course. Harm reduction was the clearest example. From a certain religious perspective, you're enabling sin. From a public health perspective, you're preventing death. Both things are true in their own frame. The question is: which frame do you choose when lives are at stake?
And you chose the lives.
I did. But I tried to do it in a way that didn't require anyone to abandon their beliefs. I just asked them to expand their circle of concern.
Your work took you to very different places—Indonesia, Vietnam, African countries. Did the science change, or did the approach to dialogue change?
The science was constant. But the cultural and political context was completely different in each place. In some countries, the barrier wasn't religion but government repression. In others, it was both. You have to listen to what's actually blocking people from getting care, and then address that specific thing.
What's the thing you wish you'd understood earlier in your career?
That being right isn't enough. You can have all the evidence in the world, and if you haven't built trust, if you haven't listened to the people you're trying to help, nothing changes. The science opens doors. But dialogue is what keeps them open.
