Despite what WHO says, AIDS remains one of the most challenging medical crises in human history. While death rates are dropping in some areas, one has to take a look at who's dying, where and why, which is exactly what journo Gary Taubes has done. Gruesome breakdown: "Though many of the most prominent deaths..tend to be of gay men, the percentage of the dead who contracted the disease through gay sex is now reportedly as low as 15 percent (with a large proportion still reported as unknown). Intravenous-drug users make up the biggest group, 38.5 percent, and women account for almost one in three of total AIDS deaths." [NY Mag]
