Head lice are small insects found on the heads of people. They are parasitic, since they feed on human blood. Without blood, they cannot survive. Lice that fall off a person’s head cannot survive in the environment for no more than two days. Lice do not jump and do not have wings to fly. They are most often spread by head-to-head contact with an infested person. Contact can occur by sharing infested clothing (hats, scarves, coats, etc.) or by using infested items (combs, brushes, towels, etc.). Infestations are treated with medicated shampoo. Head lice is common among school-aged children and parents can assist school nurses by often checking their children’s hair for head lice especially upon back-to-school attendance. Parents and students should be educated about head lice as it can cause embarrassment and misunderstanding. Head lice can occur among all socioeconomic groups and is not tied to poor personal hygiene or uncleanliness. Also, head lice do not carry disease.
