Avoiding Pinworm reinfection

Pinworm infection is highly contagious, spreads easily, and often comes back1

Reinfection does happen with pinworm

Reinfection can happen by touching surfaces that have already been contaminated with pinworm eggs by another person.1

Eggs are swallowed, usually after hand-to-mouth contact, and the pinworm infection begins again.1

Avoiding Pinworm reinfection

Pinworm eggs may spread to shared surfaces, such as bedding, curtains, toilets, doorknobs, towels, utensils, and furniture. These areas should be kept clean to avoid reinfection.1,2


How to avoid pinworm reinfection

Child washing hands Frequent handwashing and cleaning under fingernails can help prevent reinfection.

Avoiding pinworm reinfection should be discussed with your doctor at the time of treatment. Good hygiene habits such as frequent handwashing, bathing in the morning, and clipping fingernails are all effective means of preventing pinworm reinfection.2


Because pinworm can come back, to prevent any reinfection, your doctor may

  • Prescribe 2 courses of treatment about 3 weeks apart3
    • The second treatment is to kill any worms that hatched after the first treatment1,4
  • Prescribe treatment to other members of your household as they could also potentially be infected4
    • This means each person in the home would receive the same 2-dose pinworm treatment
