Which of the following best describes the impact Eurasian diseases had on the New World populations?

The impact of Eurasian diseases on the New World populations was devastating. The introduction of diseases such as smallpox, measles, and influenza by European explorers and settlers resulted in the decimation of indigenous populations. These diseases, previously unknown to the New World, spread quickly and caused widespread epidemics, leading to high mortality rates among Native Americans. It is estimated that up to 90% of the Native American population perished due to these introduced diseases, as they had no natural immunity against them. This demographic collapse had far-reaching consequences and significantly altered the social, cultural, and political landscapes of the New World.
