Risk factors

By Mayo Clinic staff

Risk factors for pinworm infection include:

  • Being of young age. Pinworm infections are most likely to occur in children between the ages of 5 and 14. The microscopic eggs are easily spread to family members, caregivers, or other children at school or child care centers.
  • Living in crowded spaces. People who live in institutions are at higher risk of developing pinworm infections.
  • Living in a temperate climate. While pinworms occur worldwide, they're more common in countries that don't have tropical climates.
