Detailed explanation-1: -Warfare and enslavement also contributed to disease transmission. Because their populations had not been previously exposed to most of these infectious diseases, the indigenous people rarely had individual or population acquired immunity and consequently suffered very high mortality.
Detailed explanation-2: -It was the germs such as those of smallpox that they carried on their person. Because of their long isolation, Americas original inhabitants had no immunity against these diseases that came from Europe. Smallpox in particular proved a deadly killer.
Detailed explanation-3: -With the arrival of Europeans in the Western Hemisphere, Native American populations were exposed to new infectious diseases, diseases for which they lacked immunity. These communicable diseases, including smallpox and measles, devastated entire native populations.
Detailed explanation-4: -They had never experienced smallpox, measles or flu before, and the viruses tore through the continent, killing an estimated 90% of Native Americans. Smallpox is believed to have arrived in the Americas in 1520 on a Spanish ship sailing from Cuba, carried by an infected African slave.
