A group of economists and organizations, spurred by Professor Alan Whitesite, has launched the "Free by 5" initiative calling for the free provision of ARVs to any patient that can't afford to pay. Making their arguments on both humanitarian and pragmatic grounds, the economists urge both policymakers and funders to recast the current "3 by 5" program to a free variant. A description of the initiative is downloadable as a PDF document. Fuller details and a petition are available at the University of Kwazulu-Natal.
