In our history after coming in contact with European explorer/settler the Native population of South America was pretty much wiped out by their disease. The reason, to my understanding was, that the close contact with a wide array of domesticated animal, meant that a lot of deadly disease could breed in in the old world population of humanity.
Now, on the other side the consumption of bush meat (especially apes/monkey who naturally have disease that are most likely to cross over to humans) led to some nasty stuff like AIDS and Ebola emerging in Africa.
Maybe, with some "luck" the Amazonian rain forest civilization catches similar disease which then become endemic, long before Europeans arrive. Additionally some avian flue, from chicken imported by the Polynesian trader, might help as well. In short how much of a disease ridden scum hole could South America plausibly become ?
