Ringworm is an infection of the skin which is caused by several types of fungi. The scalp, feet, groin, fingernails, or toenails can also be affected. Anyone can get ringworm. Children are more susceptible to certain types of the ringworm fungi, while other types occur equally in all age groups. Ringworm involving the nails is more likely to occur following an injury to the nails.
