Aids: Origin of pandemic 'was 1920s Kinshasa'

This is hardly news. The origin locale and timeframe (acquired zoonotically from Chimpanzees north of Kinshasa, probably around 1908, travelling by river to Kinshasa and Brazzaville, where social conditions permitted amplification and adaptation to human hosts) have been strongly supported by evidence for about a decade. David Quammen discusses it in detail in his book "Spillover". While this study adds more evidence supporting the theory, that area and timeframe was pretty much accepted as fact in the research community for some time.

Radiolab did a pretty interesting episode [1] regarding investigation in to Patient Zero. They talk about Typhoid Mary and Aids. I highly recommend it. [1]-http://www.radiolab.org/story/169879-patient-zero/

A Kinshasa origin around 1900 was already suggested in 2008:

it's real strange to me that the BBC says "Aids" and not "AIDS" when it's an acronym. Still interesting.

edit: especially when they say HIV and not Hiv
