The ABCs of Head Lice

General Information

Although lice are a communicable condition, they are not known to transmit disease or pose any hazard to you or your child’s health. Head lice are most common among pre-school children attending child care, elementary school children and household members of infested children. Lice are tiny insects the size of a sesame seed and feed on small amounts of blood. Lice lay oval-shaped eggs (called nits) that are firmly attached to hair close to the scalp, often found near the ears and neck line at the back of the head. The tiny eggs can look like flakes of dandruff, however, instead of flaking off the scalp, they stay firmly attached to the hair shaft.
