How are pinworms prevented?

Good hygiene will help reduce the spread of the parasites.

  • Hand washing after handling bedding, diapers, underwear, and other items that may contain the infective pinworm eggs will also help.

  • Clothes, especially underwear, should be changed and washed daily to help prevent spreading the disease.
  • Treating everyone infected in a household at the same time may help prevent recurrence and spread to others.
  • Because the eggs remain infective for up to three weeks in a moist environment, prevention of spread and reinfection is difficult but possible.
