Why is it that Europeans brought diseases to the new world but didn't catch any?

They caught racism. It didn't exist until America.

Do you even syphillis, bro?

They did.

Indians had better hygiene, just like today, it was the immigrants that stunk.

The short answer is that Europeans simply had more robust immune systems. Several factors contributed to this: first, Europeans had been the caretakers of domestic animals for thousands of years, and had over time grown (somewhat) immune to the common diseases that accompanied the domestication of such food sources. Native Americans, on the other hand, were largely hunters and gatherers, and even in some domestication cases, it’s thought exposure was limited.

Second, Europeans lived in more densely populated areas than Native Americans. When so many humans live together in relatively close quarters (particularly with lack of good, or any, sewage systems and the like), disease spreads quickly with the general population continually getting exposed to numerous pathogens. The Europeans’ bodies had to adapt to dealing with many of those diseases, and for those who survived, their immune systems thrived as a result.

The third factor is travel and exchange. Groups of people and animals moved around a lot in Europe and had interactions particularly through war and trade, resulting in the spread of disease across continents—and, eventually, some level of immunity for the survivors.

Well things like Yellow Fever were huge issues for most of our history and had a huge impact on major projects like the Panama Canal.

But back then people just died due to "bloody flux" and the like, not as through the CDC was testing samples of lung tissue.

The Old World was not nearly as isolated as the New World and had been exposed to a lot more than the New World inhabitants.

Syphilis is quite lethal. It's just not rapid.

its still hilarious to me that NYC was sold for some glass beads and trinkets.

You think Syphillis wasn't deadly back then? Talk to Fredrich Neitzsche
