Michael Worobey, an evolutionary biologist at the University of Arizona, is a nice guy—not the sort to seek out international controversy. But last week he found himself deluged with angry e-mails, and the Haitian Embassy and Consulates across the country were fielding hundreds of equally irate phone calls about him. Biology papers don't usually stir up so much fury. But Worobey's latest research, published in the Proceedings of the National Academy of Sciences, tracks the spread of HIV and suggests that the most common Western strain first hitchhiked its way to America around 1969 in the body of a single person—a person who almost certainly contracted the disease in Haiti.

Worobey says "Haitians are blameless for the spread of HIV. They were simply hit earlier." But a lot of Haitians feel offended anyway. Many of HIV's early victims in the West were Haitian immigrants, a link that led to "an adverse immigration policy in the United States and feelings of persecution and denial," writes Dr. Arthur Fournier in the 2006 book "The Zombie Curse." Now Haitians fear another wave of discrimination, and they're loath to believe Worobey's conclusions. "How do we know that a homosexual infected in America didn't bring HIV to Haiti instead?"  asks Raymond Joseph, the Haitian ambassador to the United States.

The new data show the chances of that scenario are "virtually nil," Worobey says. He has analyzed mutations over time in the virus, constructing a family tree for the different strains. And the tree tells him with "greater than 99 percent certainty" that HIV migrated from Africa to Haiti before it moved on to the United States. One person evidently brought the "subtype B" strain from Haiti to the United States in or around 1969. Almost all the strains found in the West today descend from that lone, unwitting patient.

The study has implications beyond Haiti. For one thing, it's now clear that "Patient Zero"—Gaetan Dugas, who slept with more than 2,500 people before dying in 1980—was almost certainly not the real Patient Zero. It also sheds new light on the earliest possible cases of AIDS in America. Some forms of HIV were quietly circulating here before 1969, and they "probably made several attempts" at spreading widely, says Dr. Beatrice Hahn, an HIV researcher at the University of Alabama at Birmingham. But "for whatever reason, those did not spawn an epidemic." If only the one from 1969 hadn't, either.

Editor's note: In a previous version of this story, Ambassador Joseph's full name and title were inadvertently omitted.

    Read THE RIVER, a journey into the source of HIV and AIDS, Edward Hooper. He researched over 4000 scientific texts and did over 600 interviews, Arvid Noe, a bisexual Norwegian sailor, is the earliest european aids case, possibly infected in Kenya in 1964. He then became a truck driver and had contacts with German homosexuals. At the time, Haiti was a popular vacation spot for gays, Germans included. It was also a stopover for two archival airline steward who dies of aids. Since type B is not an African type but branched off them later, it is impossible to know who first infected who. Certainly, at a very early stage, the disease was traveling both directions. As to the we gave Africa aids comment, Hooper agrees. The medical community might stonewall, but the first cases of aids appeared after 900000 in central Africa were given the Wistar/Hillary Koprowski oral polio vacinee, probably grown in Belgium. Suggested, but never admitted by Koprowski, is the implication that the final substrait in the attenuation of the vaccine was chimpanzee kidney tissue. In 1985, bood smples taken in Stanleyville, Congo were tested for HIV. One tested positive. It is the ealiest. The year the sample was taken was1959, Stanleyville was vaccinated in 1958.

    if you really waqnt to know where the HIV comes from. Watch this video. Worobey's research has a lot of biais. The Haitian or Africa did not bring Aids to the world, but the western world brought it to Africa. Wathc this...
