In the 25 years since the first case was reported, AIDS has changed the world. It has killed 25 million people and infected 40 million more. It has become the world's leading cause of death among both women and men ages 15 to 59. It has inflicted the single greatest reversal in the history of human development. In other words, it has become the greatest challenge of our generation.
For far too long, the world was in denial. But over the past 10 years, attitudes have changed. The world has started to take the fight against AIDS as seriously as it deserves.
