World leaders, advocates and community representatives meet at UN Headquarters and warn that global progress on HIV is slowing and could be reversed. The meeting marks four decades since AIDS first emerged as a global crisis. Participants say the momentum built through earlier prevention and treatment efforts is facing new obstacles, including financial pressures and reduced support for HIV programmes. They call attention to the risk that gaps in funding and services could undermine treatment access, prevention activities and broader health outcomes, reversing gains made over previous decades. The warning frames the current situation as a “perilous moment,” stressing the need to protect and sustain commitments for HIV responses at a time when resources are tightening. The statement reflects input not only from government leaders, but also from advocates and community representatives, emphasizing that the impact of diminished support can reach affected communities directly. The UN message underscores concern that without sustained investment and support, progress against HIV may not continue and could deteriorate in coming years.
