What are head lice?
Head lice are parasites that can be found on the heads of people. Infection with head lice is called pediculosis. (The head louse, Pediculus humanus capitis, is different from the lice that cause body and pubic-hair infections.)
How common is head lice infestation?
Head lice infestation is very common, and it has been around since ancient times. While the exact frequency of infections is unknown, estimates range from 6-12 million cases annually.
Who is at risk for getting head lice?
Anyone who comes in close contact with someone who already has head lice, or even their contaminated clothing and other belongings, is at risk for acquiring head lice. So it is easy to transmit head lice from one person to another. Preschool and elementary-school children (3-11 years of age) and their families are infected most often. Girls contract head lice more often than boys, and women contract more head lice than men.
