2  The objective of this presentation is to provide current research based information about head lice and how to manage children with lice in the school setting.  At the conclusion of this presentation the learner will: 1. Understand what head lice are and how they are transmitted 2. Understand the rationale for the recommendations to not exclude children with lice from school 3. Understand the general principles of prevention and treatment

3  First and foremost it must be acknowledged that when we hear the word “lice” we immediately have the “icky reaction”.  Parents and teachers alike have a tendency to react with great alarm, if not panic, when they hear that they have a child at home or in their classroom who has lice.  In the past, children with lice have been banished from school and advised not to return until they are “nit free”.  Parents have gone to great lengths to rid their child of lice- even resorting to calling a 24 hour hotline and using untested home remedies  School nurses have spent precious time doing classroom “lice checks” and subsequently sending children home who are found to have lice.


5  The head louse, or Pediculus humanus capitis, is a parasitic insect that can be found on the head, eyebrows, and eyelashes of people  Head lice are small, wingless insects which feed on human blood and live close to the scalp  They need human blood in order to survive  Head lice that are off of their human hosts will starve  It is generally believed that a head louse will not survive for more than 24 hours when off of its human host  Head lice are not known to spread disease  Head lice do not thrive on pets ml

6  Live lice lay eggs, these are called nits- you can not catch nits- they need to be laid by live lice  Nits are small yellowish-white (pearly) and oval shaped and are glued to the hair shaft at an angle  Once laid, it takes 7-10 days for a nit to hatch, and another 7-10 days for the female to mature and begin laying her own eggs  Head lice are clear in color when hatched, then quickly develop a reddish-brown color after feeding  Head lice are about the size of sesame seeds  Head lice have six legs equipped with claws to grasp the hair  Head lice live for approximately 30 days on a host and a female louse may lay up to 100 nits (eggs).

7  The presence of lice is usually detected by the presence of adult live lice, or nits (eggs) attached to the hair shaft  Nits are often at the nape of the neck and behind the ears  Complications of infestations are rare and involve bacterial skin infections caused by scratching and subsequent introduction of bacteria normally found on a person’s skin  Itching is the most common symptom of a lice infestation, along with the following additional symptoms: a tickling feeling or a sensation of something moving in the hair irritability and sleeplessness sores on the head caused by scratching


9  Head lice have been around for thousands of years, evidence of infestations have been found in ancient Egyptian tombs  All children are at risk for head lice  Having lice has nothing to do with hygiene, income, or any other factors except that children are social beings and are therefore at higher risk for getting head lice

10  Lice spread through direct contact  They cannot jump or fly – they crawl  The most common cause of infestation is direct head-head contact with an already infected person  Lice can survive for short periods on clothing, hats, hairbrushes, scarves, coats, sports uniforms, bedding, couches, carpeting, pillows, stuffed animals etc. so these can be involved in the spread  Dogs, cats, and other pets do not play a role in the spread of head lice

11  Screening for lice has not been proven to have a significant effect on the spread of head lice in a school community  In addition such screening has not been shown to be cost- effective  Children who are found to have lice eggs (nits) or live lice have most likely been infected for days if not weeks  The AAP recommends that healthy child should not be excluded from or miss school because of head lice, and no- nit policies for return to school should be abandoned.

12  It is the position of the National Association of School Nurses that the management of head lice should not disrupt the educational process.  No disease is associated with head lice, and in ‐ school transmission is considered rare  When transmission occurs, it is generally found among younger aged children with increased head ‐ to ‐ head contact  Children found with live head lice should remain in class, but be discouraged from close direct head contact with others

13 “Lice are not particularly contagious, they hurt basically no one, and they’re not a public health risk. Lice don’t actually matter”. Dan KoisDan Kois, senior editor at Slate and a contributing writer to the New York Times Magazine. ool_let_em_stay.html?wpisrc=burger_bar

14  It is recommended that you consult a health care provider about treatment  Treatment for head lice is recommended for persons with an active infestation  All household members and other close contacts should be checked; those persons with evidence of an active infestation should be treated  Some experts believe prophylactic treatment is prudent for persons who share the same bed with actively-infested individuals.  All infested persons (household members and close contacts) and their bedmates should be treated at the same time html

15  Treatment for head lice usually consists of shampooing the hair with a medicated shampoo containing one of the following ingredients: permethrin, pyrethrin, malathion, benzyl alcohol, spinosad, or ivermectin.  Shampoos containing lindane are no longer recommended.  Hair should be checked daily for the 10 days following treatment for newly hatched head lice. If these are present, an additional treatment may be necessary. Many of these agents require a reapplication of the treatment 7-10 days later to kill immature lice that may have hatched from eggs that were not inactivated during the initial treatment

16  Before shampooing remove clothing that can become wet or stained during treatment  Apply lice shampoo, also called pediculicide, according to the instructions contained in the box or printed on the label.  If the infested person has very long hair (longer than shoulder length), it may be necessary to use a second bottle. Pay special attention to instructions on the label or in the box regarding how long the medication should be left on the hair and how it should be washed out.

17  Machine wash and dry clothing, bed linens, and other items that an infested person wore or used during the 2 days before treatment using the hot water (130°F) laundry cycle and the high heat drying cycle.  Clothing and items that are not washable can be dry-cleaned or sealed in a plastic bag and stored for 2 weeks  Vacuum the floor and furniture, particularly where the infested person sat or lay  Do not use fumigant sprays or fogs; they are not necessary to control head lice and can be toxic if inhaled or absorbed through the skin

18  Avoid head-to-head (hair-to-hair) contact during play and other activities at home, school, and elsewhere (sports activities, playground, slumber parties, camp)  Do not share clothing such as hats, scarves, coats, sports uniforms, hair ribbons, or barrettes  Do not share combs, brushes, or towels. Disinfest combs and brushes used by an infested person by soaking them in hot water (at least 130°F) for 5–10 minutes  Do not lie on beds, couches, pillows, carpets, or stuffed animals that have recently been in contact with an infested person 

19  Routine screening is not cost effective and has not proven to have a significant effect on the spread of head lice in a school community over time  No child should unnecessarily miss time from learning  No healthy child should be excluded from or allowed to miss school time because of head lice  A No-nit policy for return to school should be abandoned
