Historians think that tuberculosis, dysentery, & parasitic diseases were common in the Americas before the arrival of the Europeans. Research on early skeletal remains has also given scientists intriguing clues to early New World diseases & treatments. In the 1970s, a pre-Columbian mummified child from Peru was examined, & the skeleton, as well as the preserved soft tissue, showed signs of tuberculosis with remnants of tuberculosis bacilli still in the tissue.
The impact of these diseases is somtimes referred to as the "Virgin Soil Epidemics," where populations were exposed to pathogens for the first time, leading to catastrophic loss of life. This rapid depopulation dramatically altered Native American societies, making them more vulnerable to European expansion and colonization efforts. The loss of elders and leaders also disrupted the transmission of oral histories, traditions, and cultural knowledge, contributing to the loss of invaluable aspects of Indigenous heritage.

This article discusses the landscape transformations brought by European settlers and their introduction of crops and livestock to the Americas, which were facilitated by the depopulation of Native communities.
Crosby, Alfred W. "The Columbian Exchange: Biological and Cultural Consequences of 1492." Journal of American History, 1972. Crosby introduces the concept of the Columbian Exchange and its impact on both the Old and New Worlds, particularly focusing on the diseases that devastated Native populations.
