'Gaetan Dugas, a Canadian air steward who has had sex with some 250 men a year for the better part of a decade, comes posthumously to be known as Patient Zero, after Randy Shilts popularizes the theory that he was the key disseminator of the virus in North America and, indeed, might even have been the first to introduce the virus from elsewhere. As to the identity of that "elsewhere" opinions are divided, but people begin to hypothesize that American gays might have become infected in the Caribbean, or in Europe. And by the middle of the eighties Western scientists begin to hypothesize publicly -- albeit cautiously -- that the origin of HIV, like so many other life-forms including Homo sapiens, might lie in Africa.

Let us take a brief look at some of the possiblities. IN 1990, when this book began, the world was still in a panic about AIDS, and both the popular press and the scientific journals were awash with different theories of origin. These ranged from the worthy and plausible, through gently whacky conspiracy theories, to the exploitative, the paranoid, and the products of serious madness.
According to these versions, AIDS came from God, and it punished homosexuals, junkies, and other perverts and reprobates. Or it came from man, who was aiming at roughly the same groups that God was after. It came from outer space, on the tail of a comet. It came from Africa,through people eating monkeys. It came from Africa, through kinky stuff with monkeys. It came from Haiti, and had something to do with swine fever and voodoo rites. It cam scientists, from a hepatitis B, or smallpox, or polio vaccine gone wrong. It always been around, but had escaped only recently from the confines of an isolated tribe. It has always been with us, and was merely syphilis, malnutrition, TB, the effects of hard drugs -- or combinations of the above -- lumped together and given a new name

Insomuch as a book can be said to have a source, , this book probably began at one of those pavement cafes with wobbly tables that lie scattered across the cobblestones of Convent Garden in central London. It was June 1990, and I had arranged a final meeting with Professor Alan Fleming, a hematologist, who was just about to return to southern Africa to take up his new posting at the Baragwanath, the huge hospital serving Soweto.'
