Fungal Infections of the Skin

Skin fungi live in the dead, top layer of skin cells in moist areas of the body, such as between the toes, groin, and under the breasts. These fungal infections cause only a small amount of irritation. Other types of fungal infections penetrate deeper and may cause itching, swelling, blistering, and scaling. In some cases, fungal infections can cause reactions elsewhere on the body. For example, a person may develop a rash on the finger or hand after touching an infected foot.
