Head lice are a problem! The facts.

For most parents, the thought of head lice is disturbing. Head lice infestation is common in the United States among children 3 to 12 years of age; according to the National Science Foundation approximately 6 to 12 million have infestations each year. The Centers for Disease Control has stated that anyone who comes in close contact with an infested person, especially head-to-head contact, can get lice. Thats just gross The most common symptom is itching. Many health professionals feel head lice are not a health hazard or a sign of uncleanliness and are not responsible for the spread of any disease. Even so, lice outbreaks are thought to account for 12 million to 24 million lost school days per year. It is generally agreed that head lice are the cause of much embarrassment and misunderstanding, many unnecessary days are lost from school and work and millions of dollars are spent on remedies each year.

Head lice are tiny, wingless insects that live on the human scalp (clean heads usually). They are about as big as sesame seeds (2-3 mm long). Head lice sustain themselves by sucking blood—just as mosquitoes do. However, unlike mosquitoes, lice cannot fly or jump from one person to another; they can only crawl. Direct head-to-head contact is the most common cause of head lice moving from one child to another. Therefore, children are more likely to get head lice from family members or sleepovers rather than at school.

Other important lice facts:

  • Human head lice do not live on animals—head lice can only survive on humans.
  • Lice need a warm environment and a constant source of food to survive. Head lice will die quickly (within 48 hours) when removed from a human head. Also a healthy louse is not likely to leave a healthy head.
  • Head lice are usually spread by direct head-to-head contact with an infected individual. Head lice are also transferred through the sharing of hairbrushes, pillows, towels or hats.
  • The presence of head lice is often misdiagnosed.
  • The current process to remove head lice is often very time consuming and often requires repeat treatments.
