Avian Flu
     

Avian influenza (bird flu) is caused by avian influenza viruses, which occur naturally in wild birds worldwide and usually causes no harm. However, it is very contagious among birds, and domesticated birds such as chickens, ducks, and turkeys can become very ill and die. Outbreaks of the particularly pathogenic H5N1 variant of the virus in Asia (China, Cambodia, Vietnam, Japan, Indonesia, Laos and South Korea) in 2003-2004, led to the deaths of more than 100 million birds, either from the disease, or killed to control the spread of the disease. New outbreaks have since occurred in Southeast Asia, and have spread to central Asia, Russia, Turkey and Eastern Europe.

The disease does not usually infect humans. However, there have been over 125 reported cases in Southeast Asia of humans contracting the disease from contact with infected birds or surfaces contaminated with their feces, resulting in almost 70 deaths. Spread of the H5N1 virus from person to person has been extremely rare and has not continued beyond one person. The Centers for Disease Control writes, "Because these viruses do not commonly infect humans, there is little or no immune protection against them in the human population. If the H5N1 virus were able to infect people and spread easily from person to person, an influenza pandemic (worldwide outbreak of disease) could begin . . .experts from around the world are watching the H5N1 situation in Asia closely and are preparing for the possibility that the virus may begin to spread more easily and widely from person to person."
