Ringworm: what it looks like and how to treat it

Ringworm (tinea) is a common fungal skin infection, not a worm. It often shows up as a red, scaly ring with a clearer center and can appear on the body, scalp, feet (athlete’s foot), groin (jock itch), or nails. You usually catch it from another person, a pet, or damp surfaces like locker-room floors.

How to treat ringworm

For most cases on skin, start with an over-the-counter antifungal cream. Look for clotrimazole, miconazole, or terbinafine creams. Apply as directed and keep using the cream for at least 1–2 weeks after the rash looks gone — stopping early is a common cause of return.

Scalp and nail infections need prescription treatment. Oral terbinafine or griseofulvin is often required for scalp ringworm (more common in kids) and for fungal nails. Oral antifungals can affect the liver, so your doctor may check blood tests and review other medicines you take.

Don’t use steroid creams unless a doctor prescribes them. Steroids can hide symptoms and let the fungus spread. If the rash is painful, spreading fast, has pus, or you have a fever, contact a clinician — that could mean a bacterial infection or a deeper issue.

Practical prevention tips

Keep skin dry and clean. Fungus loves moist environments. Change socks daily, dry between toes, and wear breathable shoes. Don’t share towels, hairbrushes, hats, or sports gear. Wash clothing and bedding in hot water if someone in the house has ringworm.

Pets can carry ringworm without looking sick, especially kittens and puppies. If your pet has spots or your family keeps getting infected, take the animal to a vet and treat both pet and human at the same time.

Disinfect common surfaces: vacuum carpets, clean gym mats, and wipe shower stalls with an antifungal cleaner. Consider antifungal powders for shoes and sweaty areas during hot months.

How do doctors confirm ringworm? Often they diagnose by sight. If it’s unclear, a skin scraping for a KOH test or a fungal culture can confirm the cause. If OTC creams fail after 2–4 weeks, or the infection is on the scalp or nails, ask for a clinic visit.

Quick checklist: use an OTC antifungal early, finish the full course, see a doctor for scalp/nail or severe cases, treat pets if needed, and practice good hygiene to stop re-infection. With the right steps, most ringworm clears up without complications.
