Data Watch: Closing a Persistent Gap in the AIDS Response

In this update to the 2012 Action Agenda to End AIDS, amfAR and AVAC argue that critical and expensive decisions made with incomplete data can undermine the response to the AIDS epidemic—even as the systems for collecting these data continue to improve. The report describes the issues and identifies critical areas where better, more complete data are needed to guide the key decisions for the response to the HIV/AIDS epidemic. It also provides an update on prevention and treatment targets set in the Action Agenda.
