Directions for national data policy for antiretroviral therapy in resource-poor settings: a focus on durable viral suppression.

The rapid scale-up (that is, full implementation) of programs to provide antiretroviral therapy (ART) for HIV in resource-poor settings has become a major objective for many less-developed nations and the agencies that provide funding to them. The success and sustainability of ART programs will depend upon durable viral suppression, the long-term maintenance of the infected on first-line treatment regimes. This article considers the data policy that will be required to achieve durable viral suppression.
