Fungal infections are common disorders that can affect the skin, hair and nails. Moist, humid and warm environments are the important factors in the development of the fungal infections. The organism may be transmitted by direct contact from person to person or by inanimate objects such as towels and linens. Fungal skin infections can cause red, scaly and itchy rashes, depending on which part of the body is affected. Topical or systemic antifungal medications are needed to treat the infection.
