Head lice

Head lice are small, grayish white insects that live in hair and scalp and occur in all socioeconomic groups and in all conditions. Head lice are often found in children in elementary school and in childcare facilities. They can be spread by close personal contact with an infected individual, by sharing combs, brushes, hats, caps, or other headgear. Itching is the most common symptom, but is not often reported. A thorough examination of the scalp is needed to find them.
