Lice

 

Head lice are tiny insects that feed on blood from the human scalp. An infestation of head lice, called pediculosis capitis, most often affects children and usually results from the direct transfer of lice from the hair of one person to the hair of another.

A head lice infestation isn't a sign of poor personal hygiene or an unclean living environment. Head lice don't carry bacterial or viral infectious diseases.

You may not be aware of a lice infestation. However, common signs and symptoms can include:

See your doctor before you begin treatment if you suspect that you or your child has a head lice infestation. Studies show that many children have been treated for head lice with over-the-counter medications or home remedies when they don't have an active head lice infestation.

Things often mistaken for nits include:

A head louse is a tan or grayish insect about the size of a strawberry seed. It feeds on human blood that it extracts from the scalp. The female louse produces a sticky substance that adheres each egg to a hair shaft. An egg is attached approximately 3/16 inch (4 millimeters) from the base of the shaft — an environment that provides an ideal temperature for incubating the egg.

Head lice crawl, but they cannot jump or fly. Most often transmission of a head louse from one person to another is by direct contact. Therefore, transmission is most often within a family or among children who have close contact at school or play. Indirect transmission is not likely, but lice may spread from one person to another by items such as:

Over-the-counter and prescription medications are available to treat head lice. Following treatment instructions carefully is important for ridding your scalp and hair of lice and their eggs. A number of home or natural remedies are used to treat head lice infestations, but there is little to no clinical evidence of their effectiveness.

It's difficult to prevent the spread of head lice among children in child care facilities and schools because there is so much close contact. And the chance of indirect transmission from personal items is slight.

However, it is generally a good practice for children to hang their garments on a separate hook from other children's garments and not to share combs, brushes, hats and scarves.
