The Kaiser Family Foundation is a great resource for health care data, analysis, research and targeted overviews.
This is their "fact sheet" on the Federal HIV/AIDS budget request from the Administration. Included is an overview of funding from 2006 through this request. Generally, the budget is organized into five broad categories -
care, cash and housing assistance, prevention, research and global/international.
I didn't catch the recent action of AIDS activists at an Obama public appearance, but read here that funding for Global AIDS programs was one point of the protest. So I went to the data.
Under the 2011 request, funds for international programs were targeted at $6.7 billion, up slightly (+2.2%) from 2010's $6.6.
Within that category there were some significant re-allocations. 100% of the Dept of Defense's allocation was removed, the Global Fund was cut 5% and the State Dept's Global AIDS Initiative was increased 4%. The GAI has some detractors.
Protest here may have been about the reapportionment from the Global Fund to the Global AIDS Initiative.
Big picture - The Administration's overall request was an increase of 4.6% - from $26 billion to $27.2 billion.
