During WWII, the US Coordinator of Inter- American Affairs (CIAA) commissioned several animated shorts from Disney, for example ‘The unseen enemy’ and ‘The winged scourge’. Who was CIAA showing these shorts to, and for what purpose? The CIAA was showing these shorts to help counter German propaganda against South America.

This also helped foster the spread of disease because there was a buildup of feces and refuse and people were in close contact with one another.

Domesticated animals played a role in the development of human disease because the humans were suddenly in closer contact with the animals and their feces/waste. Thus, disease microbes from animals would jump species and convert into human diseases (smallpox, measles, influenza, etc.). Measles is a virus disease that cannot be sustained in a population of less than about 500,000 people. Why does the virus fail to persist in smaller populations? Measles fails to persist in smaller populations because those who are infected either die quickly or have a lifetime immunity. In what ways has the measles virus adapted to its human host? The measles virus has adapted to its human host by causing continuous person- to- person transmission. Also, the favorable mutations are selected and the longer the virus coevolves with its host, the less symptoms it causes (meaning the host is less likely to realize there is a problem and t...
