Psychologists of Children's Municipal Hospital of Nizhnekamsk told the pupils of first form of school № 7 about the rules of personal hygiene, particularly the prevention of head lice. Pediculosis is specific lice parasite feeding on blood. The tendency of reducing the incidence of pediculosis in the population has been observed the last years. But the incidence of pediculosis in students of educational institutions is significant. This is due to the insufficient development of sanitary and hygienic skills in children and closer communication with each other.
