This. Overall however higher population density in Europe, along with a more grain based diet that increases exposure to vectors, and more exposure to foreign countries, led to the disparity between European and Indian immunity.

I don't know any specific diseases that were endemic to north America, but the Native north Americans lived at significantly lower population densities than the Europeans. Urbanized Europeans had much better immune systems than the nomadic north Americans simply because European cities were so filthy and had so many vectors for disease

Were medieval yurops less sanitary than the Romans? Seems like it, but maybe I'm memeing. Aztecs didn't have to deal with horses which would have reduced the shit-content of their cities by a lot.

Humans producing more than enough shit to still make it unbearably disgusting by today's standards. All in all though I have to say that Medieval Europe was a lot less sanitary than ancient Rome because Rome had aqueducts running water, bathhouses, tepidariums, public shithouses et al. People in the Middle Ages just shat wherever and threw piss from their buckets from the house into the street garbage as well they didn't even have sewer systems while Rome had the Cloaca

Did the black death make Europeans act more sanitary? Is there any account of how Europeans understood the plagues killing Indians?

I've heard it actually made them lass sanitary because people got scared of sharing stuff like bath water and towels. Medieval peoples' understanding of how sickness spread wasn't great but I think they knew they had to avoid something as obvious as weeping swellings.

There's some writings early of the Indians being a frail people.
