THE CHIMP AND THE RIVER

The real story of AIDS - how it originated with a virus in a chimpanzee, jumped to one human, and then infected more than 60 million people - is very different from what most of us think we know.

Recent research has revealed dark surprises and yielded a radically new scenario of how AIDS began and spread. Excerpted and adapted from the book Spillover, with a new introduction by the author, Quammen's hair-raising investigation unravels the mysteries of when, where, and under what circumstances such a consequential "spillover" can happen. An audacious search for answers amid more than a century of data, The Chimp and the River tells the haunting tale of one of the most devastating pandemics of our time. David Quammen he has been honored with the John Burroughs Medal for nature writing, an Academy Award in Literature from the American Academy of Arts and Letters, an award in the art of the essay from PEN, and (three times) the National Magazine Award.
