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.

Answer 1

One interesting difference was that North American Native Americans did not keep livestock in but Asians and Africans did.

This is interesting because a lot of these devastating diseases jumped from livestock to humans long ago. Asians and Africans had some degree of immunity because other strains of the viruses in question jumped from livestock to humans.

It’s why poultry is often culled as a preventative action.

Additionally contact over long periods between populations means a lot of the same diseases were floating around. The flu didn’t exist in North America prior to contact and that decimated populations but it was an old hat in the rest of the world.
