Further Outpatient Care

Consider re examination of stool specimens 3-4 weeks after therapy to determine if the parasite was eliminated. Examine fecal specimens from all family members (particularly siblings) of the index case for D. fragilis and other parasites. In addition, examine for E. vermicularis. The expense of ova and parasite (O&P) testing must be taken into account when considering follow-up and family member testing since a single O&P test costs approximately $80 in many US laboratories.



Control measures to limit spread of parasites include the following:

  • Disinfect surfaces and equipment handled by children infected by the parasite.

  • Disinfect diapering areas.

  • Separate diapering areas from food preparation sites.

  • Educate about handwashing techniques.

  • Improve personal hygiene.

  • Separate symptomatic individuals.


Patient Education

Educate patient and caregivers about the importance of effective handwashing techniques.
