Head Lice (Pediculosis)
Head lice are very small, tan-colored insects about the size of a sesame seed which live only on human heads. They live and lay eggs (nits) close to the scalp. The nits are about the size of the eye of a needle, oval-shaped, and grey, white, brown, or tan in color. Head lice depend on human blood for their survival and spread from person to person or through shared personal and household items.

Head lice is not a reportable condition but it may be beneficial for the sake of others to share information with school nurses, parents of classmates, and others about contact with head lice.
