Geneticists have traced the arrival of AIDS in America to a single person who came from Haiti in 1969.

In an article published in the Proceedings of the National Academy of Science, University of Arizona researchers analyzed archived blood samples from the first five U.S. AIDS patients. All were recent Haitian immigrants. The geneticists then looked at genetic sequences from another 117 people with HIV subtype B, the most common strain of the virus. After assembling the sequences, the researchers modeled the probability of various HIV family trees. Did the virus go from Africa to the United States? The chance of that, they found, was just .003 percent. Did it go from Africa to Haiti and then to the U.S.? The chance of that was 99.8 percent -- within the scope of the model, a near certainty. They found that Haiti, which contains more HIV strains than any other country, likely served as a breeding ground for the disease between 1966 and 1969, at which point a single person carried it to the United States. From there, the rest is tragic history. The findings won't directly produce cures or treatments. They might, however, give insight into how the disease evolved and spread -- and that, in turn, could guide research. The next step: tracing the disease back from Haiti to central Africa, where researchers believe it was acquired by visiting Haitian workers.

Almost like a faithful day in history, a pivotal point where one persons killed many without even knowing it.

I was reading about a Canadian Flight Attendent that carried the first AIDS virus. He was considered patient zero.

The first person diagnosed with AIDS, and potentially an early source of the HIV epidemic in the United States, called “patient zero,” was a Canadian flight attendant named Gaetan Dugas. He traveled extensively, and analysis of several early cases of AIDS showed that these individuals had either direct or indirect (shared partner) sexual contact with the flight attendant. The early cases were also traced to several different American cities where these infected individuals lived, demonstrating a critical role for air travel in spreading the virus.

And there's always a first, the fact is, there are probably multiple bringers in a short timeframe.

genetics is incredible that they can narrow it down to where.

I thought AIDS started out when African people started eating monkey meat,never mind the rasist jokes....:Puzzled:

All I have to say is that if they have spent so much energy on finding out something so trivial, then why are they not pouring this energy and money into finding an effective vaccine or cure?

Because they a backtracking, obviously if they go back far enough they'll have even more useful information to develop a vaccine.

It's not really that trivial. Knowing how diseases spread is vital for preventing future outbreaks of things like Avian Flu or tracking down hotspots for West Nile Virus.

Note only that but if they could find the creatures or creatures that incubated the diease...a true ground zero monkey...then they might be able to create a vacination from the blood of an animal that didn't die but only was a carrier...

it has possibilities...but that animal is most certainly dead...
