Thank you, yes very interesting article. Changes the way we think of these diseases for sure. glad there are such dedicated folks out there doing the much needed research. One thing it does bring to mind is we all need to remember to quarantine new additions and be very careful when visiting pet stores that sell birds, bird shows and friends and family that have birds, remembering how quickly and easily these viruses travel. Wash your hands, remove clothes and shoes in the garage or basement and shower before handeling your birds. Better to not go to bird shows or stores that sell birds anyway. Also good to remind us all to try to feed our friends healthy foods to keep the immune system in check...good article.
