Sub-Saharan Africa is the region of the world worst affected by HIV and AIDS. This important new book describes three scenarios of possible future developments of the epidemic in the region. The scenarios presented do not prescribe action nor predict outcomes but in vivid story-telling style explore 'what if?' questions; readers are encouraged to reflect on the scenarios and pose their own questions. The book will be of value to anyone concerned about HIV and AIDS living or working in the region, and also members of governments and officials, donors and other international organizations.
