Ringworm is widespread around the world and in the United States. The fungus that causes scalp Ringworm lives in humans and animals. The fungus that causes Ringworm of the body lives in humans, animals, and soil. The fungi that cause Ringworm of the foot and Ringworm of the nails live only in humans.
How do people get Ringworm ?
Ringworm is spread by either direct or indirect contact. People can get Ringworm by direct skin-to-skin contact with an infected person or pet. People can also get Ringworm indirectly by contact with objects or surfaces that an infected person or pet has touched, such as hats, combs, brushes, bed linens, stuffed animals, telephones, gym mats, and shower stalls. In rare cases Ringworm can be spread by contact with soil.
What are the signs and symptoms of Ringworm
?
Ringworm of the scalp usually begins as a small pimple that becomes larger, leaving scaly patches of temporary baldness. Infected hairs become brittle and break off easily. Yellowish crusty areas sometimes develop.
Ringworm of the body shows up as a flat, round patch anywhere on the skin except for the scalp and feet. The groin is a common area of infection (groin Ringworm). As the rash gradually expands, its center clears to produce a ring. More than one patch might appear, and the patches can overlap. The area is sometimes itchy.
Ringworm of the foot is also called athlete's foot. It appears as a scaling or cracking of the skin, especially between the toes.
Ringworm of the nails causes the affected nails to become thicker, discolored, and brittle, or to become chalky and disintegrate.
How soon after exposure do symptoms appear
?
Scalp Ringworm usually appears 10 to 14 days after contact, and Ringworm of the skin 4 to 10 days after contact. The time between exposure and symptoms
is not known for the other types of Ringworm. |
