- The location of this outbreak is the very most north
western piece of real estate in Iran, somewhere near the Aras River. West
Azerbiajan is nestled between the borders of Turkey, Armenia, and Azerbiajan.
- While we are happy to have the negative tests for avian
influenza, it would be very helpful to know more about the geography of
this outbreak in relation to the migratory wild bird pathways and the other
outbreaks in the region (Romania and Turkey have been confirmed to be H5N1).
A definitive diagnosis of what is killing these birds would be most helpful,
or a negative H5N1 from a world reference lab would be useful in solving
this unknown outbreak. Any information would be appreciated. - Mod.PC
