Are Humans and Beasts Too Close for Comfort?Are humans and animals in too close contact for disease dispersal? This question that is asked in the May 2000 article, Germs and sickness in a shrinking world, of "U.S. News online" is one that needs to be looked at very directly. "As globalization shuffles more people, animals, and pathogen-contaminated products around the world, biologists say infections are increasing" (Tangley 1). This shuffling of cultures occurred early with the Spanish conquistadors traveling to the New World. The lands of America and its native inhabitants would soon be introduced to a variety of new diseases thus creating a virgin soil phenomenon. Measles and smallpox were introduced by the Spaniards leaving the Native Americans too weak to protect their land. The Spanish were descending the disease gradient making them insusceptible to the few diseases that were in the Americas. McNeill's law reveals that as a more diseased experienced population comes into contact with a less disease experienced one; the most common result is the more diseased experienced country will take over. A
The domestication of farm animals dates all the way back to the Baktiare nomads of Persia. Studies showed that mosquitoes were able to survive in the wheel bays of jets traveling thousands of miles between tropical and temperate zones" (Morris 2). The virus was spread from ectoparasites (mosquitoes) coming from the regions of West African. Symbiotic relationships between parasites and host have been occurring for thousands of years. These assorted creatures migrate towards other areas that provide warmth and moisture. "Shrinking habitat is also deteriorating, which promotes growth of bacteria and other pathogens," states Robert McLean, director of the U. The West Nile fever in New York City is a prime example of how the scattering of creatures is very detrimental to the human race. The hunters and gathers switching to the agricultural and domestication of animals brought about brand new introductions of disease which was carried from culture to culture. In the case of the Spanish conquistadors, parasites aided them in overpowering the Native Americans. One of McNeill's corollaries states that as urbanization densifies, the new compact conditions invite numerous parasites to prosper. "Last summer, the West Nile killed seven elderly people and afflicted 62 others with body aches, chills, and other flu-like symptoms.
