There currently are three main sources of funds for global AIDS. Two of these are well-known (and frequently discussed on this site): the US Government (principally PEPFAR), and the Global Fund. The third, the World Bank, is less-well understood. Through 2003 the Bank has provided more than two billion dollars in loans and grants to developing countries to combat AIDS. The largest program, the "Multi-Country HIV-AIDS Program" (MAP), has provided over one billion dollars in grants to 28 African countries. There is quite a bit of information about the programs online, including a commendable level of detail about individual projects (although it is all admittedly difficult to decipher if you are not highly familiar with the Bank). As is the case with both US Government and Global Fund funding, World Bank financing for global AIDS is expected to ramp up with time and continue to be a major source of global AIDS finance.
