A new school year means more cases of head lice, especially among young children. Be on the lookout for these symptoms, and find out how to treat them: ThursdayThoughts ThursdayMotivation
Adult head lice are roughly 2–3 mm long. Head lice infest the head and neck and attach their eggs to the base of the hair shaft. Lice move by crawling; they cannot hop or fly.
Head lice infestation, or pediculosis, is spread most commonly by close person-to-person contact. Dogs, cats, and other pets do not play a role in the transmission of human lice. Both over-the-counter and prescription medications are available for treatment of head lice infestations. Image: Two lice viewed under an electron microscope.
