poultry industry, and within weeks spread to ten countries and regions
in Asia, including Indonesia, South Korea, Japan and China.

chickens, ducks and geese (over 40 million chickens alone were slaughtered
in high-infection areas), and the outbreak was contained by March,
but the total human death toll in Vietnam and Thailand was 23 people
while in china Figure is still not clear and unconfirmed report
put the tally somewhere around 50 – 60 Deaths . Recently in
