User avatar About 10% of the population will be infected with pinworms at some point. It is a very common condition.

Reinfection can occur after treatment.

Treatment is with an antihelminthic medication such as mebendizole. This is usually a single dose that is repeated in 2 weeks. If the second dose in 2 weeks is not done the new eggs hatch and cause reinfection.

Also, the eggs can survive on surfaces such as bedsheets, clothing, etc. for about 20 days. As such, a thorough washing of the bedsheets, mopping floors, wiping down all counters with a disinfectant, etc. should be done at the time of each treatment to try to prevent reinfection.

If reinfection continues to occur despite such precautions you may want to see an infectious disease specialist.

Just a few notes about pinworms that are sometimes common misconceptions. Infection is possible even in the cleanliest of situations. They are not an STD and are not signs of child abuse.

Best wishes.
