Ringworm is a contagious skin disease (and not a parasite) resulting from a fungal infection commonly caused by the fungus Trichophyton rubrum. It spreads by direct contact from other humans or from infected animals. The use of communal showers and swimming pools and the sharing of towels or sportswear can transmit infection. It can infect several areas of the skin from the scalp to the feet (known as athlete’s foot) to the groin (better known as “jock itch”) and everything in between. Ringworm infections generally result in red, itchy, scaly round patches on the skin that are not only unsightly, but can cause great discomfort. Be sure to test all remedies, even naturally derived ones, on a small area of your skin that is not infected so you will know if your skin is sensitive to the agent.
Only a qualified doctor can estimate the level of severity of the disease, prevent further complications and prescribe a proper treatment regimen for a particular case. Usually, localized ringworm of the body or flexures is treated with topical antifungal creams (clotrimazole, miconazole, terbinafine or amorolofine applied three times daily for 1-2 weeks). More diffuse infections require oral antifungal therapy (itracxonazole, though it isn`t licensed for use in children), especially for the most resistant form of ringworm, which is the lesion of toe-nails. High-doses of griseofulvin are still used in children for scalp ringworm. Normally, the medication lasts from two to three months. Thus, it`s easier to prevent the case than to get rid of it.
