No they don't, but Diamond uses the European immunities from disease (and Amerindian lack of it) to suggest that when the two groups would finally meet in the Americas, the result would be the same. (Amerindians dieing to huge epidemics, their societies being flung into chaos)
The issue with that argument is that Diamond posits that this immunity helped the Europeans conquer the Americas - which is certainly true - as part of his geocentric thesis that Eurasia was bound to conquer the Americas. The latter is manifestly false; while the Amerindians
didn't create ocean-crossing vessels of their own, there is no particular reason why they couldn't have developed them, in which case, while they would doubtless have caught diseases from the Eurasians, there is no particular reason why large-scale epidemics would have broken out. Even if they had, the Europeans would not have been in a position to take advantage of them.
I am not well read on the latest findings but I believe the biggest thing going for it is the
Terra Preta.
I can tell you from my own personal experience in Venezuela, that there are step pyramids in the Jungle somewhere near Apure, way too far north and into the thick forest to be from Incan civilization, and obviously very far away from the Mayans as well. These step pyramids and other monuments also had hieroglyphs transcribed on them.
It's a shame that before any archeological work was done on them, the government decided to build a dam and flood the whole region. So now these pyramids are under water.
I read a news report just yesterday, as a matter of fact, detailing something similar in Belize. A huge Mayan temple complex was bulldozed so that the stones could be used to pave a road.
Thanks. And super-llamas.

That's hilarious.
It was certainly the highlight of the description Atahualpa's lieutenant (I cannot recall his name, but he was only half-Inca, so therefore unusual in gaining such high position) gave him on the approaching Spanish. They were described (to paraphrase, since I no longer own the book I got this from) "great smelly men, with beards like the chosen (Incas had beards, unlike the majority of their subject peoples) who speak an unknown tongue, with silver tubes (that would be guns) that they carry everywhere. They also have several great silver barrels (Pizarro's cannons) that they will not let us near. Many of them ride super-llamas, which are far larger than any llama in your kingdom, even in the east."
Atahualpa's response was essentially "don't kill them until I've seen them for myself," despite his lieutenant advising him to kill them, take their "super-llamas" and send their corpses to every corner of the empire, as Pizarro was cleverly crafting alliances with the Incan subject-peoples on his way to Cuzco.
That last thing is intriguing, becaue there are references to large expeditions as early as the 1570s that were supposedly successful. Whereas by the 1760s a push towards the interior in Angola was quietly abandoned due to high casualties to disease.
Perhaps the alliance that existed during those earlier contacts garanteed better food, shelter and guidance to the strangers and reduced the typical casualties. I don't know. Historians of the Americas are lucky, the vast spanish archives hage largely survived. Most of the portuguese archives perished in 1755.
I would like to know how well the dutch did in the 1640s in Angola regarding casualties to disease there.
Masada might know about the Dutch.
I'm aware that there were apparently several expeditions into the Kongo by Portugal, some of which were roaring successes, mostly because you told me a long time ago and I researched it afterwards. I believe one of those expeditions even marched all the way through to the other side of Africa, ending up in Ethiopia somehow, where they interfered in a dynastic squabble. It's always surprised me, since most Europeans tended to die pretty routinely when exposed to Africa. I believe Portuguese soldiers were deserting and willingly going to prison rather than being sent to Ngola at one point, since prison had a higher survival rate.
That might be true. But, well, the old worlders conquered them with iron weapons. Screw the wonders, always go for Iron Working if you may have another civilization showing up soon.
Praetorian-rush ftw. The Maso-Americans aso foolishly skipped over The Wheel, just because they didn't have horses. No wonder they had so much trouble linking up their cities and resources.
