"Private philanthropists in the European Union and the U.S. spent some $644 million on global HIV/AIDS programs in 2011, a five percent increase from 2010, largely driven by funding from a small number of large donors, a new report [.pdf] has revealed," IRIN reports. "In their annual report, two groups -- the U.S.-based Funders Concerned About AIDS (FCAA) and the European HIV/AIDS Funders Group (EFG) -- reported that U.S. funders spent $491 million in 2011 while E.U. funders spent $170 million," the news service writes (11/9). The report notes in a footnote that "$17.4 million was deducted from the combined total to avoid double-counting of grants that were given between U.S. and European-based funders and re-granted in 2011" (November 2012).
