In four installments running from September 2003 through June 2004, Science has published a series of articles on the increasing incidence of HIV and AIDS in Asia -- a continent that holds more than half of the world's population, and where efforts to stem the disease's spread are at a critical point in a number of densely populated countries. This special online collection gathers together all of the articles in the series -- as well as an online slide show and photo collection highlighting many of the images from the project, and the stories behind them.
