When it was first revealed that a 9-year old boy had died of what finally
confirmed as AIDS in 1969, there was a brief panic of speculation that
the virus had been brought back by the A11 crew.
However, when it was confirmed that the kid died in March of 1969...
Also, there was a recent paper in Science reporting that the long-sought
animal reservoir of HIV has in fact been found: forest chimpanzee
populations in southern Cameroon have endemic SIV infections which closely
correspond to two of the three major types of HIV. There is apparently
reason to think (I forget details) that the virus originated in more
obscure monkeys in the interior, but these chimps are almost certainly the
route by which it reached humans (several times). Locals presumably got
it from bites etc., and it then made its way downriver to Kinshasa, from
which it spread via travelers.
(The reservoir of the third virus type is still unknown, but there are
plenty of ape populations as yet untested. For that matter, there may be
more types which haven't reached humans yet.)
