May 27 marked 10 years since the US Congress passed and President George W. Bush signed into law the President's Emergency Plan for AIDS Relief (PEPFAR), the largest AIDS initiative of its kind. Michael Gerson, a Bush administration PEPFAR advocate now advising the “ONE Campaign against AIDS,” characterized it as "the largest initiative to fight a single disease in human history." He added that when PEPFAR began, sub-Saharan Africa was providing AIDS treatment to approximately 50,000 people; today, that number is seven million. Gerson noted that PEPAR made "some of the fastest, most dramatic gains in the history of public health." He explained that the definitive goal was an AIDS-free generation. He stated, "We know many of the methods that are necessary now to make that happen." However, he cautioned that the question was whether the commitment would last long enough and be strong enough to use those methods.
