AR Contagious?
Dr H I read an article where they said atrophic rhinitis is common in pigs and is highly contagious among them and causes farmers a lot of money for whatever reasons... Would u say it is contagious in humans?

In some fashion it must be communicable. I suspect the host needs to be receptive in some way: poor immune status, etc. True AR is such a rare entity in the Western world that we do not know enough about it. I believe I have seen 2 cases - each improved with antibiotics (oral & topical) and office cleaning.
