Lice are parasitic insects that can be found on the human head, body, and pubic area. They feed on human blood and can cause intense itching, sores, and small red bumps that can sometimes get infected with bacteria. The female louse lays eggs (nits) that stick to hair shafts. Lice are most commonly spread through direct head-to-head or body-to-body contact, and less commonly through sharing of clothing or belongings. They cannot jump or fly, and they are more common among children in preschool through elementary school due to the close contact in these settings. Lice infestations do not lead to serious medical problems, and they are not known to spread diseases. The presence of lice does not indicate poor hygiene or low social status.
In conclusion, lice are primarily caused by direct contact with an infested person or by sharing items such as combs, brushes, or hats with an infested person. They are not known to spread diseases and do not indicate poor hygiene or low social status.
