Have I Got Worms?

How do you know if you've got threadworms?

Signs and symptoms to look out for

Most Threadworm infections are light. Often there are no symptoms, but the most common signs are:

Worm Flying Plane
  • Itchy bottom (especially at night)
  • Restless sleep
  • Irritability
  • Loss of appetite

For definitive proof of Threadworms infection, look for the following:

  • Worms on the outside surface of bowel motions - these resemble fine pieces of cotton thread, up to 1.5cm long. For further information, including pictures of actual Threadworms, see Facts about Worms.
  • Moving worms or eggs around the anus - about an hour after the child has gone to bed. Using a torch, worms should be visible to the naked eye, however a useful way of detecting eggs is the "sticky tape test". Press a piece of tape against the anus and remove - Threadworm eggs will appear as tiny white specks on the tape.

Uncommon symptoms in girls

Girl with Threadworms

Occasionally, "abnormal migration" of Threadworms may occur in girls - this is where female worms leave the anus and enter the vagina. This can lead to vulvovaginitis - inflammation of the vaginal area - with symptoms being extreme irritation and vaginal discharge. Threadworm-induced vulvovaginitis is not considered a major health threat, as worms will survive for only a limited time in this region. In such cases, young girls should be treated for the irritation caused by vulvovaginitis and of course, treated for Threadworm with a product such as COMBANTRIN®.

If vulvovaginitis is suspected, medical attention must be sought immediately.

Remember to treat the whole family

When Threadworms are detected, it is important you treat the whole family. For information on how COMBANTRIN® works, plus essential advice to help prevent reinfestation, see, Treating Worms with COMBANTRIN®.

Always read the label. Use only as directed. If symptoms persist, see your health care professional.
