A round, scaly rash on a child is often called ringworm, but eczema and other rashes can look similar.
We examine the location, border, scalp involvement, and exposures before deciding whether a fungal infection is the likely cause.
Scalp ringworm is especially important to recognize because it usually needs different treatment than a small patch on the skin.
How does it spread?
Children can acquire ringworm through infected people, animals, or shared items. Keep skin dry, change damp sports clothing, and avoid sharing towels. Have a veterinarian assess a pet with suspicious hair loss.
Treating ringworm
Many limited skin infections respond to an antifungal cream used as directed. Extensive, recurrent, or treatment-resistant disease needs medical assessment and may require oral medication. Avoid steroid creams on a suspected fungal rash unless your clinician specifically directs their use; steroids can worsen or disguise it.
Scalp symptoms need a different approach
Scaling with broken hairs or hair loss may be tinea capitis (scalp ringworm), which needs prescription oral treatment.
