Ringworm: Understanding Where It Appears & Why It Might Be Localized

Ringworm (tinea) is a contagious fungal infection that can affect any part of the body—scalp, face, trunk, arms, legs, groin, feet, nails. It is not limited to one hand or a single site.

The name “ringworm” comes from the characteristic ring‑shaped rash, but presentation varies by location (e.g., athlete’s foot, jock itch, scalp ringworm). Prompt antifungal treatment prevents spread.
