The global HIV response rarely pauses long enough for reflection. Yet as delegates gather in Brazil for AIDS 2026, there is a discernible shift in both mood and mandate. The world’s largest convening on HIV and AIDS arrives while the sector is at a crossroads—one shaped by hard-won progress, tightening resources, and a growing expectation that countries themselves will carry the response forward.

Every two years, this conference brings together tens of thousands of policymakers, researchers, community advocates, and implementers to translate evidence into action. Its significance lies not only in scientific breakthroughs, but in its role as a forum where the future direction of global HIV programming is contested and defined.

The context for AIDS 2026 is complex. HIV is no longer the acute global emergency it once was; it is increasingly a chronic, manageable condition for those with access to treatment. Yet the epidemic is far from over. More than 1.3 million new infections were recorded in 2023 alone, and the world remains off track to meet the goal of ending AIDS as a public health threat by 2030.

At the same time, the financial architecture underpinning the response is evolving. International funding for HIV has declined by roughly 30 percent since its peak, leaving many countries facing significant shortfalls and difficult choices. This shift is not temporary. Across global health, external assistance is being reshaped, with greater emphasis on bilateral partnerships, shared responsibility, and domestic financing.

For those working in HIV, this is more than a funding adjustment—it is a to reconceive how programmes are designed, delivered, and sustained.
Palladium is attending AIDS 2026 to work alongside governments, communities, donors, and partners to navigate this transition without losing the gains of the past two decades.

In practice, this means that HIV programmes that once operated as vertical initiatives must increasingly integrate into broader health systems. Surveillance, laboratory networks, and supply chains cannot be disease-specific; they must support a wider set of health priorities while maintaining the precision required for HIV services.

The COVID-19 pandemic exposed how fragile many health systems were around the world: fragmented governance, weak public health infrastructure, strained workforces, brittle supply chains, poor continuity of essential services, and data systems that could not move fast enough across diseases or levels of care. It reinforced the need for stronger foundations—integrated surveillance, adaptable workforces, resilient supply chains, and delivery models that can sustain routine care while responding to new threats.

There is also a growing recognition that HIV investments contribute directly to global health security. Decades of work through initiatives such as the U.S. President’s Emergency Plan for AIDS Relief have built laboratory capacity, strengthened surveillance systems, and developed a global health workforce that can respond to emerging threats. The same infrastructure that supports HIV testing and treatment today will be called upon to detect and respond to the next pandemic.

For the United States Government, AIDS 2026 comes at a pivotal moment. Its evolving global health strategy places greater emphasis on country ownership, co-financing, and more efficient delivery models. These principles align with the reality that long-term sustainability depends on national leadership, supported—but not driven—by external partners. This is where engagement matters most.

Our goal at AIDS 2026 is to engage with partners from across this changing landscape—working together to identify practical solutions that can sustain HIV outcomes while strengthening the systems that underpin them. That includes sharing lessons from implementation, highlighting innovations in digital health and data use, and exploring new models of collaboration with the private sector and local actors.

The conference provides a rare opportunity to bridge perspectives: from ministries of health navigating transition plans, to clinicians adapting service delivery models, to communities advocating for equitable access. These conversations are essential to ensuring that policy shifts translate into workable approaches on the ground.

It is also an opportunity to reinforce the role of implementation partners in a changing ecosystem. For decades, our contribution has always been grounded in delivery—working at the intersection of policy, systems, and services to turn strategy into action. In the years ahead, that capability will be tested by tighter budgets, higher expectations, and more complex operating environments.

There is no single solution to sustaining HIV progress under these conditions. But there are clear priorities: strengthening health systems so they can carry multiple burdens, investing in data and digital infrastructure to improve efficiency, and supporting countries to take greater ownership of their programmes.

AIDS 2026 will not resolve these challenges. What it can do is sharpen the focus on what comes next—and how stakeholders from science, health care, government and civil society will lead it.

Being part of that conversation is both a responsibility and an opportunity: to contribute practical experience, to listen and learn, and to help shape an HIV response that is fit for the future—one that protects past gains while building systems capable of withstanding whatever comes next.
