How did remote places in Asia and Africa not succumb to the same wave of disease and death that the Native Americans did?

Question

I’m not saying they weren’t affected at all, but something like 90% of Native Americans were wiped out while places like Japan and deep parts of the African interior didn’t suffer nearly as hard, even though they previously had basically no contact with Europe.

In: 1583

Answer 1

because no populations in asia or africa were that remote.

side note do you think diseases only come from europe or something?
