Risk factorsBy Mayo Clinic staff
Risk factors of ringworm of the scalp include:
- Exposure to other children. Though adults can get ringworm of the scalp, it occurs most often in toddlers and school-age children. Outbreaks of ringworm are common in schools and child care centers where the infection easily spreads through close physical contact or by touching common items, such as door handles.
- Exposure to pets. In addition, children with pets are at increased risk of ringworm. A pet, such as a cat or dog, can have the infection without showing any signs. Children can get the infection by touching or petting the animal.
Others factors that increase the risk of ringworm of the scalp include:
- Poor hygiene
- Overcrowded living conditions
