Abstract

This study was performed in order to study the prevalence of Pediculus humanus capitis (P. h. capitis). The study was carried out on pupils between 5-15 years old in a school and kindergarden belonging to the Turkish Chamber of Commerce and Stock Exchange Organization in Van City between November-December 2007. The hair of 863 pupils (especially the neck and the back of head areas), 385 girls and 478 boys, were examined for eggs, nymphs and adults of P. h. capitis. A questionnaire was given to the pupils, which was collected the following day. Lice and their eggs/nits, which were removed from the head of children were transferred to a bottle containing 5% glycerin in 70% ethyl alcohol. Later they were sent to the Parasitology Laboratory of the Health Research and Training Hospital of Yüzüncü Yıl University. Eggs/nits were found in 164 (42.6%) of the girls and in 34 (7.1%) of the boys (overall 198 (22.9%) infested pupils). The prevalence of P. h. capitis was high, especially in girls. The infestation rates observed and the evaluation of the questionnaire showed that there is a statistically significant relationships between pediculosis capitis and sex, level of family income, education level of the mother, number of baths taken per weekly, number of family members living in the same home, room number per capita, and hair length (p<0.001). However, there was no significant relationship between pediculosis capitis and cleaning materials used to wash the head (p>0.05).
