The bottleneck is the programme: "when, not whom" in the retrospective acceptability of community-based ART initiation among criminalised key populations living with HIV in Cameroon

In the fight against HIV, the virus that causes AIDS, medical science has long known that the most effective treatment is a daily pill called antiretroviral therapy. For decades, the standard way to start this treatment has been to walk into a hospital or a clinic, sit in a waiting room, and meet a doctor. This system works well for many, but it fails a specific group of people: those whose lives are already made difficult by stigma and fear. In many parts of the world, including Cameroon, being a gay man, a transgender person, or a sex worker is against the law. Because of this, these "key populations" often avoid hospitals. They fear being seen, judged, or reported to the police. When they do not start treatment, the virus spreads, and their health suffers.

To solve this, health experts have developed a different approach called community-based care. Instead of going to a hospital, people start their treatment in a safe, private space run by their own community groups. These groups are made up of peers—people who share the same experiences and understand the dangers of being outed. The idea is that if the treatment is offered in a place where people feel safe and understood, they will be more likely to accept it. But for a long time, researchers did not know if this idea would actually work in practice. They wondered if people who had been criminalized and marginalized would truly trust a new system, or if they would still prefer the familiar, albeit risky, hospital route.

A team of researchers in Cameroon set out to answer this question by looking at a real-world pilot program that began in early 2024. They focused on two major cities, Yaoundé and Douala, and followed hundreds of men who have sex with men and female sex workers who had recently been diagnosed with HIV. The goal was simple: to see where these individuals chose to start their treatment and to understand the reasons behind their choices. They wanted to know if the community model was truly acceptable to the people it was designed to help, or if hidden barriers were still stopping them.

The study involved 135 people who had started their treatment between February and November 2024. The researchers interviewed them more than a year later, asking them to look back on their decision. They found that the vast majority, 116 out of 135 people, chose to start their treatment in the community rather than in a hospital. This was not a small victory; it meant that nearly 86 percent of the participants had embraced the new model. What was even more surprising was that this choice did not depend on who the person was. Whether the participant was a man who has sex with men or a female sex worker, the rate of acceptance was almost exactly the same. The researchers also looked at age, education, and family background, and found that none of these personal factors influenced the decision.

Instead, the deciding factor was time. The study revealed that the choice of where to start treatment changed dramatically as the months passed. In the very first month of the program, only a third of the people chose the community option, while the rest went to the hospital. But as the program continued, trust grew. By July, and for every month after that, 100 percent of the people who started treatment chose the community route. The shift was not gradual; it was a sharp turn. The few people who went to the hospital did so only in the first few months of the program. Once the community option had been tested and proven safe by their peers, even the most cautious individuals moved away from the hospital.

When the researchers asked people why they made their choices, the answers painted a clear picture of what matters most to these communities. Those who chose the community center spoke of a deep sense of belonging. They felt safe because they were among friends who understood their lives. They valued the privacy and the discretion of the setting, knowing that no one outside their group would know they were there. They also appreciated that the centers were close to their homes, saving them time and travel costs. For the small number of people who chose the hospital, the reasons were purely practical. They wanted speed and convenience, not because they disliked the community idea, but because they were unsure of it at the very beginning. None of them said they felt safer in the hospital or that they belonged there more.

The findings suggest that the barrier to treatment was never a lack of willingness on the part of the patients. The hesitation was simply a matter of time and trust. When a new way of doing things is introduced, especially for people who have been hurt by the system before, it takes time for them to believe it is real and safe. The study shows that once the community model proved itself, it was accepted almost universally. The people did not need to be convinced that the medicine worked; they needed to be convinced that the place where they took it would protect them.

This research highlights a crucial lesson for public health: the best medical solution is useless if the people who need it cannot access it without fear. In Cameroon, where laws criminalize the very identities of the people most at risk, the community model offered a lifeline. It provided a space where confidentiality was guaranteed and where people could be treated with dignity. The study confirms that when these conditions are met, people will choose the community route. The only thing that held them back was the time it took for the program to mature and for trust to be built.

The success of this pilot program offers a path forward. It shows that with the right support, community groups can take the lead in saving lives. The researchers note that for this to last, the program needs to be supported by the country's own health system and budget, rather than relying on temporary outside funding. They also emphasize that while community care is a powerful tool, it does not remove the danger of criminalization. As long as the law punishes these individuals, the risk remains. But by providing a discreet and trusted way to start treatment, the community model has shown that it can bridge the gap between the law and the need for care. The story of this study is not about a complex medical breakthrough, but about something much simpler: the power of trust. When people feel safe, they will come. And when they come, they stay.
