Ringworm, despite its misleading name, is not caused by a worm at all. It’s a common fungal infection that affects the skin, scalp, feet, groin, and nails. Also known by its medical term tinea, ringworm is highly contagious and can affect people of all ages. Understanding the symptoms early can help you seek appropriate treatment and prevent the infection from spreading.
In this guide, we’ll walk you through the common signs of ringworm, how symptoms differ based on where the infection occurs, and what to watch for in children and adults.
What Is Ringworm?
Ringworm is caused by a group of fungi called dermatophytes, which feed on keratin — a protein found in the skin, hair, and nails. The infection gets its name from the characteristic ring-shaped rash it often produces on the skin. Although unpleasant, ringworm is typically treatable with antifungal medication, especially when caught early.
General Symptoms of Ringworm
Regardless of location on the body, most types of ringworm share a few hallmark symptoms:
- Circular or ring-shaped rash
A red, scaly patch with a raised edge and clearer center — this “ring” look is the classic sign of ringworm. - Itching
The affected area is often very itchy, particularly in warm or moist environments. - Red, inflamed skin
The skin around the rash may become red, swollen, or irritated. - Scaling or flaking
As the fungus grows, the skin can start to peel or flake, especially around the edges of the ring. - Spreading lesions
In some cases, multiple rings may appear, or the initial lesion may grow larger over time.
These symptoms can vary slightly depending on the part of the body affected.
Ringworm on the Body (Tinea Corporis)
Tinea corporis is the most classic form of ringworm and affects the torso, arms, or legs. It usually presents as:
- One or more ring-shaped rashes
- Red or pink raised edges that may blister or ooze
- A center that appears lighter or even healthy-looking
- Itching, often worsening with sweat or friction
These lesions can be small (the size of a coin) or grow several inches across if untreated.
Ringworm on the Scalp (Tinea Capitis)
Scalp ringworm is more common in children than adults and can be mistaken for dandruff or another scalp condition. Symptoms include:
- Scaly, itchy patches on the scalp
- Hair loss in circular or irregular patches
- Black dots where hair has broken off at the scalp
- Tender or painful scalp
- Swollen lymph nodes in the neck (in severe cases)
- Development of a large, pus-filled sore called a kerion
Scalp ringworm requires prescription antifungal medication and should not be treated with over-the-counter creams alone.
Ringworm on the Feet (Tinea Pedis or Athlete’s Foot)
Athlete’s foot is a type of ringworm that targets the feet, particularly between the toes. Symptoms include:
- Itching, burning, or stinging sensations
- Cracked, scaly, or peeling skin
- Redness and inflammation
- Foul odor
- Blisters in more severe cases
The infection often starts between the fourth and fifth toes and may spread to the soles and sides of the feet.
