Question 9

An illness outbreak occurs in New York City birds in the late 1990s. After a lengthy scientific investigation, the Centers for Disease Control (CDC) determine that the agent causing the birds to die is the West Nile virus. Outbreaks of this illness have been observed in several other countries in Asia and the Middle East across the last 50 years, but not in the United States. With this information, what would be the best categorization of this infectious agent/disease?

Accepted Answer

A)  This is clearly a reemerging infection. It's been around for a long time, and it is reappearing in a susceptible population again. 
B)  This is clearly a nosocomial infection. It's transmitted from animals to human beings in urban environments. 
C)  This is clearly an emerging infection. It hasn't been around that long, and it has made a jump across continents into a new susceptible population. 
D)  This is clearly not a concern to human beings-maybe it's emerging in animals, maybe it's reemerging, maybe it's nosocomial. But who cares? It's only in birds.

Question 15

Why are we concerned at all with monitoring emerging/reemerging diseases?

Accepted Answer

A)  These represent growing threats to human health that will require new scientific research and resources to effectively combat. 
B)  Because globalization (greater trade and travel between countries) leads to more chances for spread of illnesses into new areas and populations. Monitoring these illnesses will help us to protect people. 
C)  Because the speed of travel has increased greatly. With increased speed of travel, it is far more likely that a serious pathogenic threat from one area of the world can spread rapidly across the globe in a very fast manner. We need to monitor the occurrence of these illnesses to try to protect populations. 
D)  All of the above.
