Tinea is a fungus that can grow on your skin, hair or nails. As it grows, it spreads out in a circle, leaving normal-looking skin in the middle. This makes it look like a ring. At the edge of the ring, the skin is lifted up by the irritation and looks red and scaly. To some people, the infection looks like a worm is under the skin. Because of the way it looks, tinea infection is often called “ringworm.” However, there really isn’t a worm under the skin.
How did I get a fungal infection?
You can get a fungal infection by touching a person who has one. Some kinds of fungi live on damp surfaces, like the floors in public showers or locker rooms. You can easily pick up a fungus there. You can even catch a fungal infection from your pets. Dogs and cats, as well as farm animals, can be infected with a fungus. Often this infection looks like a patch of skin where fur is missing.
