The diagnosis of intestinal worms typically involves the examination of stool samples. Sometimes, multiple stool samples may be required for an accurate diagnosis. Blood tests can also be considered as supplementary assessments. If parents or caregivers visually observe pinworms in the perianal region of the child, treatment may commence without further diagnostic tests.

It is crucial to remember that intestinal worm infections can spread rapidly within a household. Therefore, regardless of the specific medication used, it is essential to treat all family members or close contacts. During an infection, strict hygiene practices must be observed: underwear should be washed at high temperatures, ironed if possible, and nails should be kept short.

To protect children from intestinal worm infections, the following precautions should be taken:

* Breastfeeding for the first 6 months offers a protective effect.
* When introducing complementary foods, meticulous hygiene must be practiced during the preparation, storage, and serving stages.
* When preparing formula, use reliable, preferably boiled water.
* Never consume water from unknown sources or well water.
* Avoid raw meat and meat products.
* Vegetables and fruits intended for raw consumption must be thoroughly washed.
* Children should be prevented from walking barefoot on soil, and they must always wear shoes outdoors.
* Contact with stray animals (cats and dogs) should be minimized.
