What is Ringworm?
Ringworm of the body, medically called tinea corporis, is a superficial fungal infection. Despite its name, it is completely unrelated to actual worms. The infection gets its common name from the characteristic ring-like appearance it creates on the skin surface.
It commonly affects the trunk, arms, or legs and is caused by microscopic organisms called dermatophytes. These fungi thrive on the dead keratinized tissues of the skin, nails, and hair. Ringworm is contagious and can easily spread between people, from pets to people, or through contact with contaminated everyday household objects.
Common Signs & Symptoms
Dermatological indicators to help you identify the condition early.
Circular or Ring-shaped Patches
An itchy, red, scaly patch that gradually takes on the classic circular appearance of a ring.
Active Outer Border
A slightly raised, red, or active outer margin while the skin in the center may look completely clear.
Expanding Nearby Rings
As the patch grows, it may expand outward or generate additional neighboring concentric rings.
Varying Color Pigmentations
Appears pink or red on lighter skin tones; may present as brown, gray, purple, or darker patches on deeper skin tones.
Texture Changes
Flaking, dryness, raised small bumps, or mild cracking around the perimeter of the affected area.
How Ringworm Spreads
Understanding transmission vectors is key to preventing reinfection and protecting your household.
Direct Contact
Direct, skin-to-skin contact with an infected person. Hugging, sports, or touching infected lesions spreads fungal spores.
Animals
Contact with infected pets, cats, dogs, or farm animals. Kittens and puppies are common carriers of ringworm.
Shared Items
Sharing towels, hairbrushes, clothing, bedding, or athletic gear. Fungi survive easily on unwashed fabrics.
Surfaces
Damp public areas like gym floors, locker rooms, public pool decks, or showers are ideal environments for fungal spores.
