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: -In addition to deliberate killings and wars, Native Americans died in massive numbers from infections endemic among Europeans. Much of this was associated with respiratory tract infections, including smallpox, tuberculosis, measles, and influenza (1, 2).

Detailed explanation-3: -Germs that brought disease had a huge impact as a result of the Columbian exchange (Walbert, 2008). Europeans brought smallpox and other diseases to the New World and diseases eventually killed off as much as 90 percent of the native population (Walbert, 2008).

Detailed explanation-4: -The migration began in the summer heat and continued through the winter with subzero temperatures. Trudging 16 miles each day, thousands died along the way as a result of hunger, cold, exhaustion, or disease and plague. The Indian population was decimated, and the forced migration became a “Trail of Blood and Tears”.

Detailed explanation-5: -Smallpox was the disease brought by Europeans that was most destructive to the Native Americans, both in terms of morbidity and mortality. The first well-documented smallpox epidemic in the Americas began in Hispaniola in late 1518 and soon spread to Mexico.
