In "The Wisdom of Whores", epidemiologist Elizabeth Pisani brings honesty, wit and startling pragmatism to the tawdry frontlines of sex and drugs. She explains how we could shut down HIV in most of the world with a few simple steps, with less money than we already have. We could do it now. But shockingly, it isn't happening. From the backstreets to the boardrooms, politics, ideology and cash have bulldozed through scientific evidence and common sense. "The Wisdom of Whores" is both a riveting expose of the AIDS industry and a penetrating analysis of where we've gone wrong.
