Treatment requires a combination of prevention and deworming medication, preventing fingers from touching the anus, washing around the anus with soap and warm water or herbal preparations every morning, changing underwear regularly, and steaming underwear in boiling water and exposing it to the sun to kill worms. Deworming medications include oral medications and topical creams, and you need to consult an infection doctor to choose specific medications according to the specific situation. The child’s clothes and toys should be washed regularly, and the child should be instructed to wash his hands before and after meals, avoid contact with other contaminated objects, and keep the room ventilated and dry to avoid repeated infections.
