We all know about the diseases that the Europeans spread to the new world when they started colonizing, but where there any diseases that the natives passed on to them that were brought to Europe?

I was wondering this, as it's common knowledge that the Europeans brought new diseases to the natives and killed a lot of them through their new sicknesses. However, we were never told if the opposite also happened and natives gave new kinds of diseases to the Europeans that were brought back to Europe

There's always room for discussion, but perhaps the section Impact of indigenous diseases on the Europeans from our FAQ will answer your inquiry.
