Ringworm, also known as 'Tinea', is a contagious fungal infection of the skin, and can exist anywhere on the body. Contrary to its name, ringworm is not caused by a worm, but generally is reddish to brownish raised or bumpy patch of skin that may be lighter in the center, giving the appearance of a 'ring'.
Ringworm is very common, especially among children, and may be spread by skin-to- skin contact, as well as via contact with contaminated items such as hair brushes. Ringworm spreads readily, as those infected are contagious even before they show symptoms of the disease. Ringworm is mildly contagious.
