Abstract
The new understanding that antiretroviral therapy (ART) can significantly reduce HIV transmission has stimulated scientific and political leaders to claim that ending the AIDS epidemic is now a realistic goal. At the same time and despite last year's major international political commitments to put 15 million people on treatment by 2015, large funding gaps threaten the gains already made and limit the potential to capitalize on the latest scientific progress. Underresourced clinics are managing ever-increasing numbers of people on treatment, even though there is attrition all along the care continuum, from testing to treatment initiation and long-term retention in care.
