Totally in disagreement with the statement that there wouldn't be many wrestlers competing. 20% of the population are compliant with healthcare provider's advice. That being said, Tinea Corporis is a fungus among us that must be kept controlled. Primarily hygiene (a shower "rinse" must involve preferably an antibacterial based soap). 2x weekly skin checks during season. Older kids need to be accountable--if something "looks like a worm" treatment for two weeks post disappearance. Have handy for your wrestler a tube of antifungal (it even comes in spray)....the biggest problem with recurring "ringworm" is annhilating the fungus!
Tinea capitus (scalp) requires oral griseofulvin. Please heed FDA label of pediatric usage.
Tinea pedis (athlete's foot) itchy, blistery, oozy especially around ankles & toes....antifungal!
And yes, there's another area gentleman that is in the private area more frquently known as "Jock Itch"....how quick does this clear up/return? Again an antifungal!!!
ALL are forms of fungus--all can be annhilated with vigilant, usage of antifungal OTC & prescriptive measures. Compliance in the efficacy of treatment & termination of the fungus is the bottom line.
