Ringworm
Many bacteria and fungi live in our bodies. Some of these can cause infections. Ringworm is a common fungal infection also known as tinea, which occurs when a type of fungus called dermatophytes grows and multiplies on the surface of the skin.
Ringworm lives on the outer layers of the skin, nails, and scalp. It is characterized by a red ring of small blisters or of scaly skin. When the fungus affects an area it spreads out so new rings are developed at the edge of the old ring.
Ringworm occurs in people of all ages, but children are the most prone. Ringworm is very contagious and can be passed from person to person by contact with infected skin areas or by sharing personal care items.
The fungus that causes ringworm thrives in warm, moist areas. Places most common to catch fungi are showers, swimming pools, and locker rooms.
Ringworm also affects pets. The infection can pass from pets to people through direct contact.
