Ringworm is most common in toddlers and school age children and is very contagious ( easily spread to others). Ringworm often occurs through play where there is direct skin-to-skin contact with another child who has the infection, at school or nursery.  It can also be spread through contact with clothes, hairbrushes, wet floors, showers, bath mats and towels which an infected person has touched.#####Ringworm is also spread from touching or petting an infected animal. Dogs and cats- even goats, cows and horses can be infected by ringworm. Puppies and kittens are especially prone to the infection. Less commonly, it is spread through prolonged contact with infected soil.
