Without question, a big reason for the progress made in the past decade is the sums of money brought to bear by the President’s Emergency Plan for AIDS Relief (PEPFAR), created by George Bush in 2003 and expanded by Barack Obama, and by the Global Fund to Fight AIDS, Tuberculosis and Malaria, a free-standing institution in Geneva that gets money from rich countries to fund grants to needy countries. PEPFAR spent $US6.7 billion last year on AIDS treatment and prevention, the Global Fund $US1.6 billion. Together, the two provide antiretroviral therapy to about 85 per cent of the people receiving it in the developing world - about 4.7 million people in all.
