Hi, [log in to unmask] stated that Aleutian disease among ferrets is rare unless exposure to mink has occurred. I'm not so sure this is a true statement. We have seen several ferrets here that have tested positive for Aleutian disease. I know of a shelter that is closed due to the high occurrance in their area. I am not sure where this is coming from, but I have a hunch that if all of you tested your ferrets, we would find that a lot of them would test positive. I once spoke to Dr. Williams about this and he said that appearance of signs of the disease could take up to two years from the date of exposure. I have not done any research on this recently, but this really scares me. I am going to try to approach the pet stores here about getting their ferrets tested. However, what would this accomplish? The local Petco stores see ferrets as "merchandise" that needs to be "moved", so I am sure this would have no impact. To make matters worse, the last time I spoke to Dr. Williams, he said that there are no plans from the vaccine manufacturers to develop a vaccine. This information is about a year old, so things may have changed. In my opinion, Aleutian disease should not be dismissed as a "rare" disease. I hope I am wrong. -Mark Zmyewski Cloud Nine Ferrets Huntsville, Alabama [Posted in FML issue 2788]
