Influenza A virus subtype H5N1, also known as "bird flu", A(H5N1) or simply H5N1, is a subtype of the influenza A virus which can cause illness in humans and many other animal species. A bird-adapted strain of H5N1, called HPAI A(H5N1) for "highly pathogenic avian influenza virus of type A of subtype H5N1", is the causative agent of H5N1 flu, commonly known as "avian influenza" or "bird flu". It is enzootic in many bird populations, especially in Southeast Asia. One strain of HPAI A(H5N1) is spreading globally after first appearing in Asia. It is epizootic (an epidemic in nonhumans) and panzootic (affecting animals of many species, especially over a wide area), killing tens of millions of birds and spurring the culling of hundreds of millions of others to stem its spread. Most references to "bird flu" and H5N1 in the popular media refer to this strain.
According to the FAO Avian Influenza Disease Emergency Situation Update, H5N1 pathogenicity is continuing to gradually rise in endemic areas, but the avian influenza disease situation in farmed birds is being held in check by vaccination. Eleven outbreaks of H5N1 were reported worldwide in June 2008 in five countries (China, Egypt, Indonesia, Pakistan and Vietnam) compared to 65 outbreaks in June 2006 and 55 in June 2007. The "global HPAI situation can be said to have improved markedly in the first half of 2008 [but] cases of HPAI are still underestimated and underreported in many countries because of limitations in country disease surveillance systems". On October 10, 2011 the WHO announced a total of 566 confirmed human cases which resulted in the deaths of 332 people since 2003.
Spread the strain through muscles
Tissue breaks out, breaks up
Whispered soft wings
Spread out into
Echo through halls
Reversed whispers
Pieces break off
Spread the strain through your skin
Tissue retract reflect
The change of your pathogenic
System breakdown contingency
Eradicate
Pass off the hoard to the machine
Spit out, Spit up
You will see this in your lifetime
Repeated before we could take score
Wiped out in months
Prey, soft, past,
Keep the whispered rumors quiet, infect social standings.
Invest the spread like two towers.
Spreading fire through the masses to save themselves.
Use the blood to inoculate rampid spreading panic.
Harmless sent to extinct.
The destitute prisoners.
From the past
Sway the balance into their arms.
Lay your head on the floor think of your next pacifier distraction.
Close your eyes for good
The ending is coming prepare for the eradication
The ending is coming
