Why didn’t native new world diseases impact Europeans during colonization?

304 viewsBiologyOther

I have frequently heard about how smallpox devastated the new world’s indigenous populations during the beginning of colonization because they had no natural immunity. What I don’t understand is how did the reverse not happen. I naively assume indigenous diseases would impact Europeans and probably be brought back to Europe but I have never read of this happening.

Their farming of animals was very different

The tribes of noth America weren’t great hosts for major diseases because the lack of density and mobility
