Oh that reminds me NurseKS,

The answer to your question. By rule (Rule 4-2-3) "a participant who has a communicable skin disease or any other condition that makes participation inadvisable" Basically this is alot of things. Such as.. visible Hepatitis strains i.e cold sores, warts. HIV/AIDS is included in that, although the visible compications of HIV are not usually seen until late on into the AIDS stage these include Karposi Sarcoma. Bascially if a person knowingly has HIV/AIDS they should self exclude themselves from the sport of wrestling because of the shear nature of bodily contact involved. Other things include Chicken Pox, Tuberculosis, and a number of other things.

To put it more simply, anything that looks nasty, is oozing. And if a wrestler is sick although most wrestlers don't actually go out on that mat if they have a serious condition.
