Abstract
WIDESPREAD head louse infestation (Pediculus humanus capitis De Geer) among schoolchildren has been recorded in Italy. An investigation was carried out to evaluate the prevalence and to identify the factors which contribute to the spread of the ediculosis. In this study (March 23 to April 21,1978) 1,988 pupils grouped proportionally to the numerical division in three types of schools were examined. The prevalence of pediculosis in the school population stüdied was 9.6%; no significant differences were detected among the three types of schools examined. Distribution of cases by degree of infestation and hair length was also studied. Distribution of para sitosis seems not to depend on the number of pupils in a class, while it was influenced by the size of the family. In the Elementary and Primary schools prevalence among females was twice that of males, while no relationship was detected between infestation and sex in the Nursery schools.
