USA HISTORY

Detailed explanation-1: -Between 1492 and 1600, 90% of the indigenous populations in the Americas had died. That means about 55 million people perished because of violence and never-before-seen pathogens like smallpox, measles, and influenza.

Detailed explanation-2: -In the ensuing email exchange, Thornton indicated that his own rough estimate is that about 12 million Indigenous people died in what is today the coterminous United States between 1492 and 1900.

Detailed explanation-3: -Within just a few generations, the continents of the Americas were virtually emptied of their native inhabitants – some academics estimate that approximately 20 million people may have died in the years following the European invasion – up to 95% of the population of the Americas.

Detailed explanation-4: -The death toll was likely between 20 to 56 million people. This amounted to the destruction of about 90-95% of the Native American population and about 10% of the world’s population. The majority of people died due to diseases like smallpox, which was able to spread very quickly among the indigenous population.

Detailed explanation-5: -Diseases such as treponemiasis and tuberculosis were already present in the New World, along with diseases such as tularemia, giardia, rabies, amebic dysentery, hepatitis, herpes, pertussis, and poliomyelitis, although the prevalence of almost all of these was probably low in any given group.
