1. What Is Ringworm and What Does It Look Like?

Ringworm isn’t caused by worms; it’s a common fungal infection of the skin. According to the Centers for Disease Control and Prevention (CDC), ringworm is caused by fungi called dermatophytes. Ringworm can affect the skin on the body (tinea corporis), scalp (tinea capitis), feet (tinea pedis, or athlete’s foot), groin (tinea cruris, or jock itch), or nails (tinea unguium, or onychomycosis). Recognizing the appearance of ringworm is the first step in getting appropriate treatment.

The appearance of ringworm can vary depending on the location and severity of the infection:

On the skin: Ringworm typically appears as a circular, raised, scaly rash that resembles rings. The center of the ring may be clear or contain small bumps.
On the scalp: Ringworm can cause itchy, scaly patches on the scalp and may lead to hair loss.
On the feet: Athlete’s foot can cause itching, burning, and cracking between the toes and on the soles of the feet.
On the groin: Jock itch causes itching, burning, and a red rash in the groin area.
On the nails: Nail ringworm can cause thickening, discoloration, and crumbling of the nails.
