USA HISTORY

Detailed explanation-1: -When the Europeans arrived, carrying germs which thrived in dense, semi-urban populations, the indigenous people of the Americas were effectively doomed. They had never experienced smallpox, measles or flu before, and the viruses tore through the continent, killing an estimated 90% of Native Americans.

Detailed explanation-2: -Smallpox arrived on Hispaniola by 1519 and soon spread to mainland Central America and beyond. Along with measles, influenza, chickenpox, bubonic plague, typhus, scarlet fever, pneumonia and malaria, smallpox spelled disaster for Native Americans, who lacked immunity to such diseases.

Detailed explanation-3: -Europeans had spent more time living in close proximity to one another and with animals. This meant that had been more opportunities for diseases to evolve in European society than in the Americas, hence the assymetry.

Detailed explanation-4: -Infamous plagues Modern estimates indicate half of Europe’s population-almost 100 million deaths-was wiped out before the plague subsided in the 700s. Arguably the most infamous plague outbreak was the so-called Black Death, a multi-century pandemic that swept through Asia and Europe.

Detailed explanation-5: -The Black Death (also known as the Pestilence, the Great Mortality or the Plague) was a bubonic plague pandemic occurring in Western Eurasia and North Africa from 1346 to 1353. It is the most fatal pandemic recorded in human history, causing the deaths of 75–200 million people, peaking in Europe from 1347 to 1351.
