Skin check,
and how to pass it

Why this is a rules problem, not just a health problem

NCAA data puts the scale of it. Its Injury Surveillance Program for 2013-14 through 2017-18 found skin infections associated with at least 21 percent of the practice injuries and illnesses in wrestling that required medical attention. One in five.

So every level of the sport screens for it before you weigh in. In college the exam is run by a physician, preferably a dermatologist, or a certified athletic trainer, it starts 15 minutes or less before the scheduled weigh-in, and it happens each day of a multi-day event. USA Wrestling requires every competitor to pass a medical check before reaching the scale at all. And the consequence is spelled out rather than left to the referee: in the NCAA book, a communicable skin disease "shall be full and enough reason for disqualification," and it goes in the bracket as a medical forfeit.

One detail worth knowing before you stand in that line. The NCAA appendix says male student-athletes shall wear shorts and female student-athletes should wear shorts and a sports bra for the examination. USA Wrestling runs its check in the competition singlet, and specifies that girls and women wear a singlet designed for female athletes.

Ringworm, which is not a worm

The most common one you will meet, and the one wrestlers name after the sport: tinea corporis gladiatorum. CDC is blunt on the first misconception: "Ringworm is caused by fungi (not a worm)." The medical name is tinea plus the body part, so tinea pedis is athlete's foot and tinea capitis is on the scalp.

What it looks like. The American Academy of Dermatology describes "Roundish, flat patches that have a raised, scaly border," where "The center of a patch tends to clear first," which is what makes the ring. Colour depends on your skin: CDC says the rash "typically looks red on light skin and appears gray or brown on darker skin," and AAD says patches on skin of colour are usually brown or gray. On the scalp it presents differently, as a scaly bald patch, sometimes with black dots in it.

How it moves through a room. CDC lists three routes, and a wrestling room supplies all three: "Skin-to-skin contact with people or animals with the infection. Shared objects like towels and bedsheets. Shared surfaces like locker room or public bathroom floors." It names participating in contact sports like wrestling as a risk factor outright.

One thing not to do. CDC warns that steroid creams can make ringworm worse. The leftover hydrocortisone in the bathroom cabinet is the wrong tube.

Impetigo and the rest of the bacterial group

AAOS describes impetigo as spreading rapidly over 24 to 48 hours, and gives the look that makes it recognizable: "Clusters of red, round, scaly patches with scalloped borders" covered with a "yellow, honey-colored crust." That honey crust is the tell. Folliculitis, the same family, shows as "small, white pustules" sitting in individual hair follicles, and AAOS notes it is easily spread by shaving.

The rule books group all of it together with boils, cellulitis, staph and MRSA, and treat them on one timeline, which is why the table below has one bacterial row rather than five.

MRSA, and why it is on this page

CDC: "MRSA is a type of staph that can be resistant to several antibiotics," and it "spreads in the community through contact with infected people, wounds, or things that have touched infected skin." A staph skin infection shows up as a bump or an infected area that is "Red. Swollen. Painful. Warm to the touch. Full of pus or other drainage."

The line that matters most for a wrestler is about mistaken identity: "People sometimes confuse some MRSA skin infections with a spider bite. However, unless you actually see the spider, the irritation is likely not a spider bite." The spider bite that appeared after practice is the one to get looked at.

The NFHS form builds the same suspicion into its guidance from the other direction. If new lesions continue to develop or drain after 72 hours of treatment, it says MRSA should be considered. A bacterial infection that is not responding on schedule is information, not bad luck.

CDC also notes that MRSA "can survive on some surfaces, like towels, razors and furniture, for hours, days or even weeks." That is the sentence that explains the hygiene list further down.

Herpes gladiatorum

The one the rules treat most strictly, and the only one on this list that does not go away. The Minnesota Department of Health, which has tracked outbreaks in high school wrestling for years, calls it "a skin infection caused by the Herpes Simplex type 1 virus," and says it "is spread by direct skin-to-skin contact."

What it looks like, and when. "Herpes gladiatorum lesions appear as a cluster of blisters and may be on the face, extremities or trunk." The warning often comes first: "Before skin lesions appear, some people have a sore throat, swollen lymph nodes, fever or tingling on the skin." And the timing is why an outbreak in a room is traceable: "Generally, lesions appear within 8 days after exposure to an infected person, but in some cases the lesions take longer to appear."

It stays. The virus is not curable. It can hide in the nerves and reactivate later, causing another infection, and recurrences are contagious too. The NCAA book notes that wrestlers with a history of recurrent herpes labialis or herpes gladiatorum could be considered for season-long preventive treatment, decided with the team physician. That is a conversation to have in October rather than in February.

Minnesota's instruction to athletes is one sentence and it is the whole prevention strategy: "report any skin lesions or sores to your coaching staff immediately."

The timelines, side by side

These are minimums, and they are the actual published numbers rather than a coach's memory of them. High school comes from the NFHS Medical Release Form, approved by the NFHS Sports Medicine Advisory Committee in April 2024. College comes from Appendix C of the NCAA women's rule book, revised August 2019. Where they differ, they differ on purpose.

Covering it does not work, and one exception that is not what you think

This is the part people get wrong, and the NFHS form quotes the rule so nobody has to guess. Rule 4-2-3 ends: "Covering a communicable condition shall not be considered acceptable and does not make the wrestler eligible to participate." The form says the same thing in its own words: covering a contagious lesion is not an option allowed by rule, while covering a non-contagious lesion after adequate therapy, to protect the lesion itself, is fine. The order matters. Cleared first, then covered.

USA Wrestling goes further and names the specific dodge. Any wrestler who turns up at the medical check with makeup or a temporary tattoo over a skin lesion is disqualified for the event, with a red alert issued.

The one real exception sits on the college side, and only for ringworm. The NCAA guidelines allow a student-athlete with documentation of a diagnosed tinea infection, under treatment, in a coverable area, to participate even though the 72 hours have not expired. "Adequately covered" is defined tightly: a gas impermeable dressing, pre-wrap and stretch tape, anchored so it cannot be dislodged during the sport activity. The on-site physician or trainer decides whether the area counts as coverable, and disqualifies extensive or multiple lesions, or any lesion not under documented treatment. High school has no equivalent allowance, so at a Saturday tournament the answer is the 72 hours.

Two categories are never coverable in either book: active purulent bacterial lesions, and active herpes.

The form, and who signs it

High school runs on the NFHS Medical Release Form for a wrestler to participate with a skin lesion. It records the diagnosis, the location and number of lesions on a body diagram, the medications used, the date and time treatment started, the form's expiration date, and the earliest date the wrestler may return. The coach hands it over at weigh-in for the dual or the tournament.

Three things about it are worth knowing in advance.

• Your state decides who can sign. The form says so directly, so check with your association rather than assuming a walk-in clinic's signature travels.
• An on-site professional can overrule it. Rule 4-2-4: if a designated on-site health care professional is present, they may overrule the diagnosis of the professional who signed the form, in either direction. In the NCAA book the same principle is stated as the host site's physician or trainer making the final medical determination, and Appendix C says the on-site decision "should be considered FINAL."
• Chronic conditions get a season-long note. Rule 4-2-5 lets a wrestler carry documentation for a specific non-communicable condition such as eczema, psoriasis or a birthmark, valid for the season, with the understanding that a chronic condition can become secondarily infected and may need re-evaluation. If you have eczema, get that note in November and stop re-arguing it at every tournament.

One more line from the form that is easy to miss and worth reading twice. The NFHS committee states that no definitive data exists that allows anyone to predict exactly when a lesion stops shedding organisms. These numbers are a consensus, not a laboratory threshold. Which is the argument for treating them as the floor rather than the target.

Hygiene that is actually in the guidance

Short list, because these are the ones with a named source behind them rather than the ones in a locker room poster.

• Shower immediately. AAOS: "Shower as soon as possible after every practice and game." Minnesota's guidance for wrestlers says the same.
• Nothing shared touches skin. AAOS: "Do not share towels, soaps, lotions, disposable razors." CDC adds washcloths.
• Put something between you and shared surfaces. CDC: "Use barriers, like a towel or clothing, between your skin and shared surfaces." AAOS says the same for shared equipment.
• Cover every cut until it heals. CDC: "Keep cuts and scrapes clean and covered with bandages or dressing until healed," and do not pick at sores. Broken skin is the way in.
• Clean gear on the same cycle as your body. Minnesota: change gear daily, clean equipment regularly, wash your hands.
• Say something the day you see it. Every source on this page lands in the same place, and it is the cheapest thing on the list.

The day you find something

Get it looked at, that day if you can, because every timeline above starts when treatment starts and not when you first noticed. Tell your coach or trainer before you next step on a mat, since a room finds out eventually and the only variable is how many people it took with it. Ask for the form and the return date in writing at the appointment, rather than calling back on Friday for it. And do not treat a guess with somebody else's prescription: the rule books ask for a diagnosis and a documented start date, and neither is something a teammate can give you.

The rest of the tournament-day checklist, including what to have in the bag, lives in the tournament bag.
