Avian Bornavirus

By Alyson Burgess, About.com

Definition: Avian Bornavirus was discovered in the summer of 2008. It is a virus exclusive to members of the psittacine family, and is believed to be the precursor to PDD in affected parrots

As of yet, it is unknown how Avian Bornavirus spreads amongst birds, and there is no treatment for the disease it causes. If you suspect that your bird may have PDD, contact an avian veterinarian immediately.
Examples: Scientists identified Avian Bornavirus in over 70% of samples collected from birds infected with PDD.
