Pinworms (enterobiasis)

Enterobius vermicularis

C’est quoi

Pinworm infection, also known as enterobiasis, is a common infection that is not serious. It is caused by small white worms in the intestine and often causes no symptoms. With a new infection, small worms may be visible in the stool (poop), and itching may occur around the anus, especially at night.

What you can do at home

What to do
  • Ask a pharmacist about treatment for the infected person and anyone who lives with them or has had close contact with them.
  • Everyone should start treatment at the same time.
  • Repeat the treatment after 2 weeks.
  • Follow the pharmacist’s treatment instructions.
  • If the area is itchy, ask a pharmacist for advice before applying an ointment, cream, or lotion.

On the first day of treatment

  • Wash bedding, towels, and washcloths in hot water.
  • Vacuum the bedrooms.

To prevent spreading the infection

  • Wash hands often, especially after using the toilet and before eating.
  • Keep nails short and clean.
  • Avoid putting fingers in the mouth, biting nails, or scratching around the anus.
  • Clean the toilet seat thoroughly.
  • Take a shower every day, preferably in the morning.
  • Change pyjamas every day.
  • Change underwear every day and always put on clean underwear after showering.
  • Do not shake clothing or bedding, as this may spread the eggs.
  • Regularly clean and disinfect frequently touched surfaces and objects, such as toys.
  • For babies and young children: Use mittens or close-fitting underwear to prevent scratching.
À éviter
  • Baths as the water may contain pinworm eggs.
