There is something called tinea versicolor, which is not a true "ringworm", but I contracted it (as did every other member of the household I worked at, and the housecats) either from the horses or bales of hay. Doctors will say that it is not something that is "spread", and yet everyone came down with it over the course of a week and we had it for at least six months. I had ring shaped patches that eventually filled in with red, was not raised, but eventually flaked (like dandruff only very light). On the head, it caused dandruff; on the face, it caused dry skin and flaking, and on the chest and arms and neck caused red spots. Eventually I looked like a burn victim, and I was the one most afflicted - since I was the one brushing the horses, cleaning the stables, and baling hay. What is interesting is that the housecats also came with with it, as did the wild cats. I have pictures of my condition and the cats, and they lost fur where they got the ringworm/versicolor. I would like to remind everyone that doctors do not know *everything*, and there are still many vets that like to say that ferrets don't contract any illnesses from cats (which they do, my vet has finally admitted). So as far as what I was diagnosed with - tinea versicolor, which can look very much like ringworm (did they do a wood lamp test on your son? or just look and diagnose), this can be spread - I'm not sure if it's spread person to person, but perhaps by some other means. I was confused by your post - did your ferrets get it already? Or were you just talking about your son? Sincerely, Laryssa [Posted in FML 6747]
