Types of fungal skin infections Some common fungal infections are listed below. Dermatophyte infections Most basic fungal skin infections are caused by dermatophytes - a type of fungi that cause skin, nail and hair infections. They are common, affecting between 10 and 20% of people at some point in their life. They include: Athlete's foot (Tinea pedis) This is a very common infection that occurs in one in five adults. It's often caused by a combination of fungi and bacteria. It causes scaling and sogginess of the skin, commonly of the web spaces between the toes. Sometimes the skin becomes pale and can be itchy. The infection is often picked up from contaminated skin fragments in public places, such as swimming pools and shower facilities. Ringworm of the groin (Tinea cruris) This is called “jock itch” because it occurs in sportspeople. It causes an itchy, red rash in the groin and surrounding area and is commonly seen in those who have been sweating a lot. Ringworm on the body (Tinea corporis) This affects the body, often in exposed areas like the abdomen or on limbs, causing red patches. They are scaly at the edge with clear skin at the center.The patches spread out from the centre. It may also be caught from domestic animals. Ringworm of the scalp (Tinea capitis) This tends to affect young children and can cause hair loss with inflammation in the affected area. It is usually spread from person to person. Most people infected by this fungus don't actually develop the symptoms, but become carriers who can spread the infection to others, sometimes for years. Nail infections Onychomycosis is the name for any fungal nail infection. Tinea unguium (ringworm of the nails) is a common infection. The nails become malformed, thickened and crumbly. Not all nails affected like this are caused by fungal infections, but it is a common cause. Toenail infections are commonly linked with athlete's foot. Fingernails can be affected too.
