Ringworm is a common fungal infection - not a worm. It can cause a round, scaly, itchy patch on the skin, but scalp and nail infections need different treatment. A clinician should evaluate a rash that is on the scalp, spreading, painful, or not improving.
When to Seek Care
Get emergency medical care now
A rash with severe trouble breathing, swelling of the lips or tongue, fainting, a seizure, or a child who is limp or unresponsive.
A child who looks very ill, has rapidly spreading redness, severe pain, swelling around an eye, or a fever with a worsening skin infection.

Pus, yellow crusting, warmth, tenderness, fever, or spreading redness around a rash. These may signal a bacterial skin infection in addition to or instead of ringworm.
A round or scaly patch on the scalp; broken hairs, patchy hair loss, scalp swelling, or swollen neck glands. Ringworm of the scalp requires prescription medicine by mouth; creams alone do not cure it.
A ring-like rash after a recent tick bite, especially if it is expanding. Not every circular rash is ringworm.
A child with a weakened immune system, a widespread rash, infection of the face or nails, or a rash that is rapidly spreading.
Contact during office hours
The diagnosis is uncertain, there are more than a few spots, the rash keeps returning, or it has not clearly improved after about 1 to 2 weeks of appropriate treatment.
Your child has ringworm and participates in wrestling or another close-contact sport. Ask the clinician and team about return-to-play requirements.
A household pet has a patchy, scaly, or hairless rash, or several people in the household develop similar rashes.
What Ringworm Can Look Like
Ringworm, also called tinea, is a skin infection caused by a fungus. On the body or face, it often appears as a slowly enlarging round or oval patch with a raised, scaly edge and a smoother center. It may itch, but it does not always look like a perfect ring and can look different on different skin tones.
The same type of fungus can cause athlete's foot, jock itch, scalp ringworm, or nail infection. Eczema, psoriasis, insect reactions, bacterial infections, and some tick-bite rashes can resemble ringworm, so an examination is useful when the pattern is unclear.
Safe Home Care for a Small Body Rash
For a small, typical patch on the body, an over-the-counter antifungal product may be appropriate when used exactly as the label directs or as a clinician recommends. Apply it only to intact skin and follow the full treatment duration even if the rash begins to fade.
Do not use a steroid cream alone, a combination steroid-antifungal product, or someone else's prescription on a rash that may be ringworm. Steroids can alter the appearance and make fungal infections worse.
Keep the skin clean and dry. Do not scratch, pick, or cover the area with an airtight dressing. Wash hands after touching the rash or applying medicine.
Do not use an antifungal cream as a substitute for evaluation of scalp, nail, widespread, or recurrent infections. These commonly need prescription treatment.
Preventing Spread and Repeat Infection
Do not share towels, washcloths, bedding, hats, hairbrushes, combs, clothing, shoes, socks, or sports gear. Wash items after use.
Keep skin dry, change socks and underwear daily, and wear sandals in locker rooms, public showers, and around pools. Shower after practices or games.
Check pets with scaly, itchy, or hairless patches. A veterinarian should evaluate a pet suspected of having ringworm.
Clean sports equipment and do not share it. Tell the school, childcare program, or athletic program when appropriate so they can follow their own attendance and hygiene policies.
School, Childcare, and Sports
Many children with a small treated body rash can attend school or childcare, but each program and sport may have its own rules. Ask whether the rash should be covered and follow guidance for close-contact activities such as wrestling. A scalp infection, untreated widespread rash, or a draining or bacterial-looking lesion needs individualized instructions.
