Essay on the History of Bird Flu:

Bird flu or avian influenza is a viral disease of birds — it spreads in different countries by ignoring the different laws through the migra­tory birds. It is a highly contagious poultry disease, causes high mortality in poultry birds. The disease is known to us for more than a century.

The most recent outbreak of the disease was in February 2006, from India where the poultry farms were highly affected in some parts of the country like Maharashtra (Nandurbar and Dhule district), etc. The severity was so much that 50,000 chickens were reported to have died in a week and about 900,000 chickens were slaughtered and buried. But no human infection was confirmed, though it was suspected at that time.

There have been a number of small out­breaks of bird flu in human beings since 1997 and showed a high mortality rate. The disease in humans was first reported in 1997 in Hong Kong, where 18 people were infected and 6 people died.

Since then it was also found in China, Vietnam, Thailand and other countries. More attention has been given since some strains infect humans. In spite of that, in 2003 in Hong Kong two people were infected and one died. Recently, in 2004, in East Asia, as many as 10 deaths have been linked to an outbreak of the disease.
