Ringworm on Scalp Overview

Scalp ringworm (tinea capitis) is a very common fungal infection among children throughout the world. Fungal organisms known as dermatophytes cause scalp ringworm by superficially infecting certain types of tissue found in hair, skin, and nails. This forms the crusty, scaly patches associated with scalp ringworm.

• In the United States, an estimated 3-8% of the population is affected by scalp ringworm. Some people can be carriers of the organism and spread it to others in the household. In other countries, an estimated 9.6% of people are affected, and nearly 40% can be carriers.

• Children aged 4-14 years are most likely to develop ringworm of the scalp, although it can occasionally appear in adults.

• Scalp ringworm occurs most frequently in urban areas among people with low incomes living in overcrowded quarters.

• This disease tends to be more severe in children with weakened immune systems, such as those with diabetes, AIDS, or cancer.
  
  
• Ringworm found on the body differs from scalp ringworm and is caused by a separate organism.
