AIDS 2026 Opens in Rio as Global HIV Response Faces Severe Funding Pressure

RIO DE JANEIRO — The 26th International AIDS Conference has opened in Rio de Janeiro at a critical moment for the global HIV response, bringing together people living with HIV, researchers, governments, healthcare workers, donors and community organisations.

AIDS 2026 is taking place from 26 to 31 July at the Riocentro Convention and Event Center and through online participation. Organisers expect the conference to provide a major platform for scientific evidence, policy debate and community advocacy as the world approaches the 2030 target for ending AIDS as a public-health threat.

The conference is opening amid what the World Health Organization and the International AIDS Society describe as an unprecedented funding crisis. Reductions in HIV programme financing are placing pressure on prevention services, testing, treatment continuity, surveillance and community-led programmes, especially in countries that depend heavily on international support.

WHO is expected to launch the first global mid-term assessment of progress under the Global Health Sector Strategies on HIV, viral hepatitis and sexually transmitted infections. The assessment will examine achievements, remaining gaps and the action required to restore progress towards the 2030 goals.

The organisation will also present updated guidance on prevention, diagnosis, treatment and monitoring. Planned discussions include doxycycline post-exposure prophylaxis, stronger HIV surveillance, integrated maternal and postnatal services, and approaches that combine community-led care with primary healthcare.

A central concern is how health systems can protect effective services when funding is reduced. Community organisations often reach people who experience stigma, criminalisation, poverty or discrimination and may be less likely to use conventional health facilities. Losing these services could increase late diagnosis, interrupted treatment and new infections.

The conference will also examine simplification, self-care, integration and the practical use of digital technology and artificial intelligence in HIV services. These tools may help extend access, but they must be supported by privacy protections, reliable infrastructure and human oversight.

AIDS 2026 takes place four years before the 2030 deadline. The scientific progress achieved in recent decades has made HIV a manageable long-term condition for millions of people with access to effective treatment. The present challenge is ensuring that funding instability does not reverse those gains.

The conference’s importance will therefore be measured not only by new research announcements, but by whether governments and donors make credible commitments to prevention, treatment access, community leadership and sustainable national financing.
