AIDS 2026 - 26th International AIDS conference

Scientific progress over the 40-plus years of the HIV response has transformed HIV into a manageable condition if you have access to treatment. By the end of 2024, the number of AIDS-related deaths had dropped by 54% and new HIV acquisitions by 40% since 2010. HIV treatment is now so effective that the virus can be undetectable and, therefore, untransmittable. We have highly successful long-acting HIV prevention options, including the injectables, lenacapavir and cabotegravir, with a long-acting oral prevention technology on the horizon.

Despite these gains, UNAIDS data suggests stagnant progress in recent years: 1.3 million people acquired HIV and 630,000 people died of AIDS-related causes in 2023 and again in 2024. There continue to be huge gaps in HIV prevention and treatment: 9.2 million people living with HIV were not getting life-saving medicines in 2024. This is because old barriers to HIV services persist. Among them are stigma and discrimination, criminalization and structural inequalities between populations and countries.

In early 2025, the suspension of US foreign aid, including PEPFAR, triggered a funding crisis that threatens to widen those gaps. This underscores the urgent need for countries to strengthen domestic financing, improve efficiencies and prioritize sustainability.

We have to work together to prevent the current crisis from rolling back progress.

Join the International Aids Society at the 26th annual AIDS conference in Rio de Janeiro and virtually from July 26-31, 2026, for vital conversations to rethink, rebuild and rise.
