The short answer

Tinea corporis is ringworm on the body, appearing as circular, scaly, red patches with a raised border and clearer center. It is caused by dermatophyte fungi and is contagious. It responds well to topical antifungal cream applied for 2 to 4 weeks. Pets, other children, and contaminated surfaces are common sources.

  • Usually normal when: A single ringworm patch that responds to antifungal cream within 1 to 2 weeks
  • Call your doctor if: A ringworm patch becomes very swollen, boggy, painful, and oozing, suggesting a kerion reaction
  • Varies by age — see the age-by-age breakdown below

It is caused by dermatophyte fungi and is contagious. It responds well to topical antifungal cream applied for 2 to 4 weeks. Pets, other children, and contaminated surfaces are common sources. At 0-3 months, body ringworm is uncommon in very young infants. If a ring-shaped rash appears, your pediatrician should confirm the diagnosis, as nummular eczema can look very similar. Antifungal treatment should only be started after proper diagnosis. It is generally considered normal when a single ringworm patch that responds to antifungal cream within 1 to 2 weeks.

Normal vs. Concerning

Usually Normal
Worth Discussing
A single ringworm patch that responds to antifungal cream within 1 to 2 weeks

By Age

What to expect by age

0-3 months

Body ringworm is uncommon in very young infants. If a ring-shaped rash appears, your pediatrician should confirm the diagnosis, as nummular eczema can look very similar. Antifungal treatment should only be started after proper diagnosis.

3-6 months

If ringworm is confirmed, apply over-the-counter clotrimazole or miconazole cream twice daily for 2 to 4 weeks. Continue treatment for at least one week after the rash appears clear to prevent recurrence. Keep the area clean and covered when possible.

6-12 months

Babies may contract ringworm from pets (especially cats and dogs with skin patches) or from other children. The rash typically starts as a small red patch and expands into a ring shape over days. It may itch mildly. Wash bedding and clothing in hot water during treatment.

12-24 months

Toddlers in daycare or who have pets are at higher risk. If ringworm is widespread or not responding to topical treatment, oral antifungal medication may be needed. A skin scraping can confirm the fungal diagnosis. Your child can attend daycare once treatment has been started.

What to Tell Your Pediatrician

  • Describe when you first noticed body ringworm (tinea corporis) in baby and how it has changed over time.
  • Note your baby's current age and which age-specific patterns you are seeing.
  • Mention if multiple ringworm patches on the body.
  • Mention if ringworm not improving after 2 weeks of topical antifungal.
  • Let your doctor know if you have noticed any related concerns, such as changes in feeding, sleep, or movement patterns.
  • Bring a list of any questions or observations you want to discuss at the appointment.

What Should You Do?

When to take action

Probably normal when...
  • A single ringworm patch that responds to antifungal cream within 1 to 2 weeks
  • Gradual clearing of the ring from the center outward with treatment
Mention at your next visit when...
  • Multiple ringworm patches on the body
  • Ringworm not improving after 2 weeks of topical antifungal
  • Ringworm keeps recurring after completing treatment
Act now when...
  • A ringworm patch becomes very swollen, boggy, painful, and oozing, suggesting a kerion reaction
  • Widespread body fungal infection with signs of immune compromise

What You Can Do at Home

  • Keep track of when you notice body ringworm (tinea corporis) in baby — noting the time of day, duration, and any triggers can help your pediatrician.
  • Remember that a single ringworm patch that responds to antifungal cream within 1 to 2 weeks — this is generally within the range of normal.
  • At 0-3 months, focus on observation rather than intervention unless your pediatrician advises otherwise.
  • Use fragrance-free, hypoallergenic products on your baby's skin. Avoid over-bathing — 2-3 baths per week is usually sufficient.
  • While monitoring at home, seek immediate care if a ringworm patch becomes very swollen, boggy, painful, and oozing, suggesting a kerion reaction.

Treating Ringworm in Baby

Ringworm (tinea) is a common fungal infection that causes a ring-shaped, scaly rash. It is treated with over-the-counter antifungal cream applied twice daily for 2 to 4 weeks, even after the rash looks better. Ringworm is contagious but your child can return to daycare once treatment has started. It is not caused by a worm despite the name.

Is It Ringworm or Eczema?

Ringworm and eczema can look similar, but ringworm typically forms a distinct ring shape with a clearing center and raised, scaly edges, while eczema tends to appear as irregular dry, red patches. Ringworm is a fungal infection (not actually a worm) that is treatable with antifungal cream, while eczema is a chronic condition managed with moisturizers and sometimes medicated creams.

Circular or Ring-Shaped Rash on Baby

A ring-shaped or circular rash on a baby can be caused by ringworm (a fungal infection), granuloma annulare, nummular eczema, or Lyme disease. Ringworm is the most common cause and is easily treated with antifungal cream. If the ring has a clear center with a raised, scaly border, ringworm is very likely. A ring-shaped rash following a tick bite needs prompt medical evaluation.

Scalp Ringworm (Tinea Capitis) in Baby

Tinea capitis (scalp ringworm) is a fungal infection of the scalp that causes scaly patches, itching, and areas of hair loss. Unlike ringworm on the body, scalp ringworm requires oral antifungal medication because topical creams cannot penetrate the hair follicle adequately. The hair typically grows back fully after successful treatment.

Circular or Ring-Shaped Rash on Baby

A ring-shaped or circular rash on a baby can be caused by ringworm (a fungal infection), granuloma annulare, nummular eczema, or Lyme disease. Ringworm is the most common cause and is easily treated with antifungal cream. If the ring has a clear center with a raised, scaly border, ringworm is very likely.

The hair typically grows back fully after successful treatment.

My Baby Has an Extra Nipple (Accessory Nipple)

Accessory (supernumerary) nipples are one of the most common minor congenital findings, occurring in about 1 in 18 people. They appear as small, flat, often pigmented bumps along the "milk line" — an embryonic line running from the armpit to the groin on each side. Most people mistake them for moles. Accessory nipples are almost always harmless and require no treatment. In rare cases, they may be associated with kidney abnormalities, so some pediatricians recommend a renal ultrasound if one is found, though this practice varies.

My Baby Was Born with a Raw Spot on Their Scalp (Aplasia Cutis)

Aplasia cutis congenita (ACC) is a condition where a baby is born with a small area of missing skin, most commonly on the scalp. It occurs in about 1 in 10,000 births. The affected area may look like a raw wound, an ulcer, or may have already healed into a thin, shiny scar by the time of birth. Most cases are small, isolated, and heal well with basic wound care — the area eventually forms a hairless scar. Larger defects or those associated with other findings may need more investigation, but isolated small ACC has an excellent prognosis.
