Travel and Trade Gave Humans Immunities Against Diseases

If you think about how the the Native Americans died from disease when the Europeans landed in the Americas, you find that they were not immune against disease. Europeans with their immune systems could battle diseases like influenza, typhoid, measles and smallpox. But these diseases had a devastating effect on Native peoples who had never encountered them before and had no immunity for them, killing off an estimated 90% of Native Americans since the arrival of Columbus. This was largely due to the biological isolation and the limited intrusion of infectious diseases in America before A.D. 1492. It was only through travel and trade that boosted immune systems of humans everywhere – not lockdowns and isolations.


“One of the brave and intelligent voices here is Sunetra Gupta, the professor of theoretical epidemiology who leads a full team of experts at Oxford University. 

Her understanding is so profound that she has, in an interview, offered up a fascinating thesis concerning why the flu pandemic of 1918 was the last truly catastrophic plague we’ve seen in the modern world. 

Gupta’s claim is that when we live in isolated tribes that are sheltered from exposure, those people gradually become weaker and more vulnerable. The wrong pathogen arrives at the wrong time and the people have not been biologically prepared for it. It wipes them out in shocking ways. But with modern capitalism came the end of such sterile isolation. It gave us new methods of travelling, mixing, associating, moving, and hence led to more exposure to disease and the resulting antibodies. Hence, it is not just better therapeutics and vaccines that helped us conquer some plagues but immunities themselves. Our biological toolkit for fighting disease became improved simply through travel, trade, and global commerce.”
