Question 12

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.

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.
