It is important to understand what ringworm is, how it is spread, and how it is treated. Ringworm is not caused by a worm. It is a minor superficial skin infection caused by a fungus similar to the fungus that causes athlete's foot. It is considered a nuisance infection, and there are no long-term problems associated with it.
Treatment is both easy and effective.
When someone has ringworm he or she usually has one or more scaly, circular patches on their skin. These patches are usually itchy. Applying medicated lotion to affected areas treats ringworm. In cases that involve the scalp, an oral medication is used. Again, both treatments are very effective.
