Avian flu is caused due to the H5N1 virus which is transmitted from the saliva, fecal matter of the birds. The disease is highly contagious and causes death of birds and poultry population. The virus is lethal and assumes the proportion of pandemic, which can wipe out the entire population of birds and poultry. The virus also spreads to the human beings if they are in contact with the sick bird or poultry. Human beings are also afflicted by the virus which can even be life threatening.
Avian influenza is flu infection in birds. The disease is of concern to humans, who have no immunity against it. The virus that causes this infection in birds can mutate (change) to easily infect humans. Such mutation can start a deadly worldwide epidemic.
Avian’ refers to birds and ‘flu’ is the common name for influenza. Some countries (particularly in Asia) have been affected by bird flu infecting their poultry stocks, and a small number of people have caught the bird flu virus from being in close contact with infected chickens. There have only been a small number of incidents of bird flu in the UK where it has been found in poultry and a couple of wild birds. All cases of bird flu in the UK have been well controlled and there have been no cases of human illness associated with any incidents.

Avian flu causes severe symptoms and can result in death.
