Summary Introduction
Introduction: Avian influenza virus (H5N1) is a type of influenza A virus that is pathogenic and affects birds. It causes a disease known as bird flu. This disease causes respiratory disease in birds. Humans are infected only when they are in close contact with the infected birds or with environments contaminated with H5N1 virus. H5N1 viral disease is considered to be a promising pandemic threat. A pandemic disease is the spread of an infection worldwide affecting larger human populations.

What is the major difference between common cold and flu? Why has no vaccine been developed for the common cold?
Viruses are considered non-living microbes, and yet they are responsible for many major disease outbreaks in humans, animals, and even plants. Consider the following:
How are these non-living microbes able to reproduce without metabolic functions?
Can viruses be exploited to help humans fight bacterial pathogens?
Which viruses are able to stay dormant in the human body and reactivate later in life or when immune defenses are compromised?
What impact might travel outside of the United States have in blood, tissue, or organ donation?
