Risk factors
Risk factors for pinworm infection include:
- Being young. Pinworm infections are most likely to occur in children ages 5 to 10. The tiny (microscopic) eggs are easily spread to family members, caregivers, or other children at school or child care centers. Pinworm infections are uncommon in children younger than age 2.
- Living in crowded spaces. People who live in institutions are at higher risk of developing pinworm infections.
