Colonial clue to the rise of HIV
BBC ^ | 1 October 2008

Posted on 10/01/2008 5:53:13 PM PDT by Lorianne

The arrival of colonial cities in sub-Saharan Africa at the dawn of the 20th Century may have sparked the spread of HIV.

US experts analysed one of the earliest samples of the virus ever found, in the Democratic Republic of Congo in 1959.

The study, published in the journal Nature, suggests the virus may have crossed from apes to humans between 1884 and 1924.

They believe newly-built cities may have allowed the virus to thrive.

Aids, the illness caused by HIV, was first reported by doctors in 1981, but the virus had been around for many decades before that.

Scientists believe that these "founder events" may have involved eating monkeys infected with a similar virus.

Research published last year found the viral ancestor of a subtype of HIV responsible for most modern cases in the US and Europe in a blood sample taken in Leopoldville, the capital of Belgian Congo - now Kinshasa, the capital of the Democratic Republic of Congo.

Now the same team, from the University of Arizona at Tucson, has found another sample containing a different subtype in a 1960 sample from a different patient in the same city.

By analysing the genetic differences between the two viruses, and calculating the amount of time these differences would take to evolve, they now say that the two probably have a common ancestor dating from at least 50 years earlier.

I got a little trouble with the prohibition against pork. Ham, bacon, ribs, sausage, ribs, ribs, ribs, pulled pork, ribs.

Also I like shellfish, too. Shrimp, crab, lobster, crayfish, calamari.

Thank goodness the NT did away with all that.

Just how desperate the poor schmuck who enabled the crossover must have been. Perhaps one of the left over Muslim men who would be wife was taken by some rich dude for his 3rd or 4th wife instead.

:'D I'm working days, and at night I've got an actual structured bedtime (in order to be up in the morning); free hours are spent soaking in a hot bath, reading the accumulated book supply here. I've been off and on sick all summer, and the soaking and rest makes me feel better. (':

But yeah, I'm waaaay behind. Here's a sample of what I have yet to post:
