Ringworm is a common fungal infection of the skin seen most often on the scalp, body, feet ("athlete's foot"), or groin ("jock itch"). Ringworm actually isn't a worm at all — its name comes from how it looks, like a red ring or group of rings with clear centers.
Signs and Symptoms
On the skin:
starts as a red, scaly patch or bump
circular pattern with raised, bumpy, borders (often with a scaly center)
On the scalp:
may start as a round, reddish, pimple-like sore
becomes patchy, flaky, scaly, or crusty (may first be mistaken for dandruff)
causes swelling, tenderness, redness, bald patches (usually circular), and broken hairs
What to Do
Call your doctor if you think your child has symptoms of ringworm.
Follow the doctor's treatment instructions carefully. Depending on the type and site of the infection, these may include using over-the-counter or prescription cream for the skin, or prescription oral medication for the scalp.
Discourage your child from picking at the infected area since this could cause infection.
Contact your doctor if increasing redness, swelling, or pus occurs.
Prevent ringworm by encouraging your kids to:
avoid sharing combs, brushes, hair accessories, pillows, hats, and headphones
wear flip-flops at the pool or in the locker room shower
