As you said, right now, no one really knows for certain just how contagious ADV is and how easily it is spread. I do not really have any personal experience to relay on maintaining a population of both positives and negatives. Although I do have both, by the time I knew I had a problem, all of my ferrets had been exposed, and I assumed they would all become positive, so I made no effort to separate the positives from the negatives. To my surprise, though, that did not happen. After the initial infection, the ones that were negative have remained negative. Apparently, some ferrets have a natural immunity to ADV, or are able to fight the virus off. After 3 1/2 years, I still have no new positives. I still retest about every 4 months, because I don't know if the immunity is lifelong or not. Currently, after some losses and some additions, I have 21 ferrets, with 7 that are ADV+. All additions to my population have either been ferrets that were ADV+, or from homes with ADV+ ferrets, so they were already exposed. As to safety of bringing in ferrets to a home after all ADV+ ferrets have passed, there is, unfortunately, no definite answer. However, several of us talked with Dr. Mary Ann Stevenson about this over dinner at the Symposium 2002, and she felt that if you thoroughly cleaned your house and waited a few months (she suggested 3 to 6 months) after the last positive was gone, that it would probably be safe. Here were some of her suggestions for preparing for new ferrets after have ADV+ ferrets: 1) If possible, remove all carpet and rugs - carpeting is almost impossible to properly clean, and also the most likely source of lingering ADV germs, especially if the ferrets have ever pottied on it. Remember - bleach and parvocides are not effective in cleaning porous surfaces like carpeting and cloth. They are only completely effective on hard surfaces. 2) Throw out any ferret bedding and toys and replace with new. 3) Thoroughly clean all cages, litter pans, and floor surfaces with a parvocide and/or bleach solution. When possible, do not rinse the solution off and allow it to air dry, or air dry, and then rinse. Before using the parvocide, make sure all solid waste material has been removed. Soaking dried on poop in parvocide is not always effective, the dried on poop needs to be removed. If you have hard wood floors, consider refinishing the floors and covering with clear polyurethane. This will protect your floors against future damage, and seal in any germs. Dr. Stevenson felt that upholstered furniture could also be a potential problem. Not everyone can afford to refurnish their house just to get new ferrets, although replacing any upholstered furniture would be preferable. However, if furniture isn't replaced, she suggested at least having it thoroughly steam cleaned once, and maybe even twice. Hopefully, as more research is done on ADV, we will learn more about how the disease is spread, and just how contagious it really is. Until then, being as careful as possible is the best we can do.
