More than 2,000 ducks have died from the H5N1 bird flu in Siem Reap and Battambang provinces since Thursday in the first outbreak of the virus since March 2014, according to officials and the World Organization for Animal Health (OIE) on Tuesday.

?It has not spread to any people because the farms were far from the villagers? houses....

The tests turned up positive: the birds had the H5N1 strain of avian flu...
