Ringworm all over the body: what to know

Ringworm is a fungal infection of the outer skin. Patches may be itchy, scaly, dry, raised at the edge, or clearer toward the centre, but not every rash has this pattern. Several areas can become involved after contact with an infected person, animal, or shared item, or when one untreated patch spreads to nearby skin. A body-wide rash can also have other causes, including irritation, eczema, or an allergic reaction.

A clinician may inspect the distribution, ask about contacts and pets, and test skin scale when the diagnosis is uncertain. Mention every affected location, including the scalp, nails, groin, feet, or face, because those sites can change the treatment plan.

Arrange a medical review rather than applying different products to each patch. A clinician may recommend [Topical Antifungal Treatment](/treatments/medical-dermatology/topical-antifungal-therapy/) for limited skin areas or [Oral Antifungal Treatment](/treatments/medical-dermatology/oral-antifungal-therapy/) when infection is extensive, difficult to reach, or involves hair or nails. Use treatment for the instructed duration and avoid steroid-only products unless prescribed.

Keep affected skin clean and dry, wash hands after applying medicine, and use separate towels and clothing until advised otherwise. Launder bedding and clothing, avoid sharing personal items, and arrange veterinary advice for a pet with suspicious bare or scaly patches. Marking where patches are located can help you notice whether new areas are appearing.

Seek prompt care for fever, severe pain, pus, rapidly spreading redness, facial or eye involvement, a swollen scalp, or extensive blistering. Request review if new patches continue to appear after treatment starts, if the diagnosis is uncertain, or if a child, older adult, or person with reduced immunity is affected. Use the [Skin Rash](/symptoms/skin-rash/) and [Scaly Skin](/symptoms/skin-scaling/) pages to describe the visible pattern, not to replace an examination.

Ask whether all affected sites are ringworm, whether testing is useful, whether tablets are needed, how to protect household members, and what signs would show that treatment should be changed.
