Why did Europeans coming to the Americas not pickup diseases from the indigenous populations?

by swallamajis

I was always taught about Europeans bringing terrible diseases to indigenous populations, having terrible impacts because of the lack of immunity. Why is the reverse not true? wouldn't the indigenous populations not have had diseases that the Europeans were not immune to?

I commend to your attention the appropriate section of the FAQ, which addresses both notions of European invaders versus American diseases and Native Americans versus European diseases.
