More on the reported Mongolian bird flu deaths

I spoke with a colleague that works in Mongolia, who reported the following:

"I just spoke to the veterinarians at the [Mongolian] Institure of Veterinary Medicine.  The reported avian flu in 500+ birds in 30 soums and 16 different aimags reflects citizen reports of dead birds NOT serologic evidence of AI exposure.  I am not yet sure whether or not the report of "an additional five geese, two shelduck, and four gulls were found dead at Erkhel Lake in Alag-Erdene soum, Khovsgol aimag, on September 22" is based on serologic evidence of disease or not."

As I don't want to use his/her name, I guess this information will have to be taken at face value.
