Read full review Selected pages. The HIV-1 group M pandemic probably first began in the s. From there it jumped species into humans on several occasions, perhaps because people ate infected bushmeat. The virus spread quickly through the population.
And it seemed to come out of nowhere. In fact, only one form of HIV has spread far and wide after jumping to humans. It was likely due to one of two things: The story of the spread of HIV is not over yet Belgian Congo gained its independence, and became an attractive source of employment to French speakers elsewhere in the world, including Haiti. But even when HIV has passed into human populations from these apes, it has not necessarily turned into a widespread health issue. This technique is widely used, for example to establish that our common ancestor with chimpanzees lived at least 7 million years ago.

The virus spread quickly through the population. But HIV that came from monkeys has not become a global problem. Off to the left, a couple of rhesus monkeys scampered about, and some even jumped onto the railing surrounding the shelter. Tooey owned a river-cruise tourist attraction and thought the monkeys would be a defining trait of the ride. It's unclear why they attacked, as they rarely do. A likely sequence of events quickly became obvious. Because they knew where each of the HIV samples had been collected, they could place the origin of the pandemic in a specific city: When these young Haitians returned home a few years later they took a particular form of HIV-1 group M, called "subtype B", to the western side of the Atlantic. From there it jumped species into humans on several occasions, perhaps because people ate infected bushmeat. The very first person to be infected with HIV-1 group M probably picked up the virus in the s Genomes pick up new mutations at a fairly steady rate, so by comparing two genome sequences and counting the differences they could work out when the two last shared a common ancestor. It arrived in the US in the s, just as sexual liberation and homophobic attitudes were leading to concentrations of gay men in cosmopolitan cities like New York and San Francisco. They turned to historical records to work out why HIV infections in an African city in the s could ultimately spark a pandemic. It ticks so fast, Faria and his colleagues found that the HIV genomes all shared a common ancestor that existed no more than years ago. A study published in suggests a surprising answer: As of this writing, the original video has nearly 7, views, and that number will likely go up quickly as word travels around the interwebs. Kinshasa, now the capital of the Democratic Republic of Congo.
