Enterobiasis is the most common helminth in the USSR. Despite of its clinical manifestations in children, some parents do not see a doctor. 105 parents were interrogated by questionnaires. 71% of them called the reason why they had taken no medical advice and the rest evaded the question. The parents' questionnaire is an important measure for preventing and controlling enterobiasis with regard to better health education methods used in the work with parents and tutors from pediatric institutions.
