Ringworm (also referred to as tinea infections) is a fungal infection of the skin, hair, or nails that gets its name from the ring-shaped rash it often creates. Despite the misleading name, no worm is involved—the infection is caused by fungi called dermatophytes that feed on keratin, a protein found in the skin’s outer layers.
Because it spreads so easily, ringworm is considered highly contagious. It can pass through direct contact with an infected person or pet and also through shared items like towels, clothing, sports equipment, or even floors in locker rooms and showers.
Although anyone can develop ringworm, certain groups are more prone. Children often catch it through play, athletes may develop it from skin-to-skin contact or shared gear, and people in hot, humid climates face higher risk. Individuals with weakened immune systems are also more susceptible and may experience more persistent infections.
While the condition isn’t dangerous, it often causes itching, redness, and irritation, and can be a source of embarrassment. Fortunately, antifungal treatments—applied topically or taken orally—are very effective. Alongside treatment, preventive steps like good hygiene, avoiding shared personal items, and promptly treating affected pets or family members can help stop the infection from returning.
Signs & Symptoms
- Circular or ring-shaped patches with a clearer center and a raised, scaly border. Lesions may appear red, inflamed, or darker depending on skin tone.
- Can develop almost anywhere, including the arms, legs, trunk, neck, scalp (tinea capitis), feet (tinea pedis/athlete’s foot), and nails (onychomycosis).
- Usually causes itching, sometimes accompanied by burning or irritation, depending on the severity.
- Left untreated, ringworm can spread to other body areas or to others through direct or indirect contact. With antifungal therapy, infections usually improve within several weeks.
Causes & Risk Factors
- Direct contact with infected people or pets (especially cats and dogs)
- Sharing contaminated items such as towels, clothing, or gym equipment
- Walking barefoot in communal spaces like locker rooms or pools
- Excessive sweating or humid environments
- Weakened immune system or underlying health conditions
Treatment Options
- Topical antifungal prescriptions for most skin infections
- Oral antifungal medications for scalp, nail, or widespread infections
- Skin care guidance to prevent reinfection and reduce spread
