Instead, other diseases, notably HIV/AIDS, have been prioritized. Since its emergence, HIV/AIDS has been at the forefront of the global health policy agenda and has generated considerable interest, funding and political action, disproportionate to the burden of the disease. (9) Despite challenges such as: global health threats from other diseases, varying regional disease burdens and the imperative need to strengthen health systems; the majority of donor aid is devoted to HIV/AIDS. For example, during the re-emergence of tuberculosis, as mentioned previously; WHO's budget for tuberculosis in 1992/93 was about $10 million, compared to $160 million for the Global Program on AIDS. (15) In 2003, the Bush administration introduced the President's Emergency Plan for AIDS Relief (PEPFAR), a five-year, $15 billion plan and, by 2006, 80% of the US budget earmarked for health. and aid to the population was reserved for HIV/AIDS. This shows that HIV/AIDS has remained a global health policy priority for global health stakeholders for a considerable period, despite other issues increasingly demanding policy attention..
