Huge numbers of people living in the Americas died from diseases when Europeans started coming over. It is always stated that this is because the immune systems of the Americans had not contacted the European diseases before. Why did the same thing not happen in reverse? Why weren't 90% of some European settlements wiped out from an unfamiliar American disease?
