Jock itch Tinea cruris infection Tinea capitis infection Ringworm is the commonly used term for various fungal infections of the skin, scalp, and nails. The infections may be acquired by physical contact with infected people or animals, or from contaminated objects or surfaces.
The most common type of ringworm is probably athlete’s foot.
Body ringworm (tinea corporis) produces an itchy, red or silvery ring on the skin of the body. Groin ringworm (tinea cruris, commonly called jock itch) produces a reddened, itchy, flaky patch that spreads from the genitals over the inside of the thighs. Scalp ringworm (tinea capitis) produces round, itchy, scaly patches of hair loss on the scalp. In all these types of ringworm, blisters or sores may form around the edge of the affected area.
Ringworm of the nails typically causes thick, discolored nails.
Treatment is usually with topical antifungals, although antifungal tablets may be needed for widespread infections or those affecting the scalp or nails.
