Fungal infections are a common type of skin problem that can also affect the hair and nails. Also called tinea, infections can occur on any part of the body. Ringworm, jock itch and athlete’s foot are some of the most recognized names for fungal infections on the body. Fungal infections frequently affect teens and children, but adults can also get fungal infections. Topical medications are usually effective for treating fungal infections. However in some cases, oral medications may also be needed. A dermatologist will prescribe the best treatment after examining the infection.
