|MadSci Network: Science History|
In my history classes we often read about how european explorers to North America, South America and Australia introduced diseases to the indigenous populations that had no resistance to these diseases, resulting in widespread deaths. Some books attribute extensive depopulation to these diseases. My question is why were no diseases transmitted the opposite way, from the "new" worlds to europe with similar results of widespread deaths?
Re: Why didn't early explorers take new diseases home with them?
