Dermatophytosis, which you might know as ringworm, athlete's foot, or jock itch, is a skin infection caused by tiny fungi. These fungi love to feed on keratin, a tough, protective protein found in your outer skin, your hair, and your nails.
Because these fungi live in the top layers of your body, they don't usually cause deep or dangerous infections. Instead, they create itchy, red, or scaly patches on your skin. It is very common, and while it can be annoying, it is usually easy to treat.
Common Symptoms
- A red, scaly, or bumpy ring-shaped rash on the skin.
- Itchy skin in the affected area.
- Cracking, peeling, or blistering skin, especially between the toes.
- Discolored, thick, or brittle nails.
- Patches of hair loss or broken hair on the scalp.
