New HIV infections data among key populations: proportions in 2010 and 2022

On 1 January 2024, the Journal of Acquired Immune Deficiency Syndromes (JAIDS)  published an article describing the findings from UNAIDS and co-authors on new HIV infections among key populations1 and their sexual partners in 2010 and 2022, by world region. For the first time, UNAIDS and partners have used expanded data sources and refined, dynamic HIV transmission models to make estimates of new HIV infections with time trends within each country and key population.

This article, prepared by UNAIDS and partners, highlights the new methods used to gain a better understanding of new HIV infections among key populations. The article focuses primarily on the new methods and necessary improvements for future estimates. This document places the findings in the wider context of the AIDS epidemic and response for their advocacy and programmatic use. For additional information, data and nuances it is suggested to refer to the full article.
