Europeans often spread infectious diseases to Native Americans through trading and settlement efforts, and these could even be transmitted far from the sources and colonial settlements, including through exclusively Native American trading transactions.
Endemic is a frequently misunderstood and misused word outside the realm of epidemiology. Endemic does not mean mild, or that COVID-19 must become a less hazardous disease.
