Aids deaths at lowest level in over thirty years

In 2025, Aids-related deaths worldwide fell to 570,000, a 57% decline compared to the peak recorded in 2010. This is the lowest level in over three decades, according to the special report published by UNAIDS, the United Nations programme on HIV/Aids, ahead of the AIDS2026 conference.

The improvement concerns the global population affected by the epidemic: new HIV infections have also decreased, by 42% since 2010. However, the figure remains far from the elimination of transmission: in 2025 alone, 1.2 million people became infected worldwide, a number that measures how much work remains to be done alongside the progress recorded on the mortality front.

The death figure comes from UNAIDS’s special report for the AIDS2026 conference, a document from the United Nations agency responsible for monitoring the global response to the epidemic. It is therefore an estimate produced by the international surveillance body on the matter, not by an entity that derives a direct commercial benefit from the reported figure — a distinction that strengthens its reliability as a measure of a global health phenomenon, while still remaining an aggregate estimate on a worldwide scale rather than a clinical study on a defined sample.

The same report introduces a note of caution regarding the future: UNAIDS warns that reductions in international funding allocated to the HIV response risk leading to a resurgence of the epidemic, undoing part of the progress recorded over the past fifteen years.

The overall picture therefore tells a dual story: on one hand, the lowest number of Aids-related deaths in over thirty years, and on the other, a flow of new infections — over one million people in 2025 alone — which remains a measure of how the goal of ending the epidemic has not yet been achieved.
