The spread of Old-World diseases in the Americas during the Columbian Exchange and the importance of international cooperation in managing modern pandemics.
The introduction of Old-World diseases to the Americas during the Columbian Exchange led to devastating epidemics among Native American populations. Europeans had developed immunity to endemic diseases over time, while Native Americans had no resistance to these new pathogens, resulting in up to 90% of Native Americans perishing from infectious diseases brought by Europeans.
Migration and concentration of human populations have facilitated the exponential spread of diseases worldwide, impacting urban areas significantly. Globalization enables the rapid transmission of diseases like influenza and COVID-19, emphasizing the importance of international cooperation in managing pandemics.
Pathogens introduced by European settlers triggered epidemics in the Western Hemisphere due to lack of immunity, leading to a drastic decline in Native American populations. Diseases such as smallpox, measles, and influenza substantially reduced the indigenous population, highlighting the severe impact of disease transmission in historical contexts.
