Ringworm is a fungal infection on the skin. Different types of fungus may infect different areas of the body, and the symptoms vary some between the different types. An individual may have several types of ringworm infections at one time. Ringworm is a contagious infection that thrives in warm, moist environments and spreads easily from person to person through direct contact. Treatment for all types of ringworm involves using an antifungal medication.
Types
Tinea capitis is a ringworm infection involving the scalp. Tinea corporis is a ringworm infection involving skin on the body. Tinea pedis, commonly referred to as athlete's foot, infects the feet and areas between the toes. Tinea cruris, also referred to as jock itch, affects the skin surrounding the genitals, including the inner thighs, pelvis and buttocks.
Symptoms
Ringworm causes an itchy rash in the affected area. The skin may have a red ring-shaped rash with a flesh colored center. The rash may also appear scaly. Ringworm affecting the scalp or face may cause bald patches in the hair or beard area, according to MedlinePlus. Ringworm infection on the groin and feet may cause red, itchy skin with severe itching.
Treatment
The use of antifungal medications helps treat a ringworm infection. Over-the-counter topical antifungal medications are available with different main ingredients and in different forms. Some forms include cream, lotion and powder. Ringworm infections involving hair or infections that do not respond to over-the-counter treatments may need prescription antifungal medication, according to the University of Maryland Medical Center.
Complications
Most ringworm infections respond to treatment and resolve in several weeks. As with all medical conditions, complications are possible. Scratching the rash may open the skin and allow bacteria to enter the wound. A bacterial infection may require antibiotics. Unhygienic conditions and scratching the rash may cause a spread in the infection and begin to involve other areas of the body.
Prevention
Preventing a ringworm infection may be possible when taking measures to avoid conditions that allow the fungus to thrive and spread. Keeping the skin clean and dry may help deter the fungal infection. Avoiding conditions that encourage fungal growth, such as public showers, may prevent the transfer of the fungus. Wearing shoes in public areas such as a locker room and a pool may help avoid contracting athlete's foot. To prevent contracting ringworm from someone else, an individual should not share personal items such as clothing, linens, and hairbrushes.
