Avian influenza is in the same virus family as seasonal flu. Poultry has proven to be very sensitive to the virus, which results in high mortality.

The illness, which infects chickens and many other birds, has pushed egg prices through the roof in the past few months. Vaccinating flocks, however, could hurt the poultry industry on the global market.

As the ongoing bird influenza continues to devastate the nation’s egg production, Turkey plans to export eggs into the U.S. through July in a preliminary agreement reached between the two nations.
