Global access to treatment: achievements and challenges.

: As mentioned in the previous issue, this section of the Review addresses issues related to improving access to adequate and affordable care, treatment, and support everywhere. It replaces the section previously called "Patents and Prices." In this issue, we feature a review of achievements and challenges in recent years in opening global access to HIV/AIDS treatments. The article - one of a series commissioned to mark the tenth anniversary of the Canadian HIV/AIDS Legal Network, discussing past developments and future directions in areas of policy and law related to HIV/AIDS - describes the developments that recast the debate about access to treatment from one focused on patent entitlements to one focused on the right to health and treatment. It analyzes the role of national and international activism, strategically constructed alliances, and principled leadership in achieving this change. And it discusses continuing obstacles to equitable access to HIV/AIDS treatments for the world's population.
