Head Lice
|
||||||||||||||||||||||||||||||||||||
|
People get head lice from
direct contact with other people who are infested by wearing infested
clothing, using infested brushes and combs, lying on infested carpets or
beds, and from resting the head against upholstered furniture or car
seats formerly used by an infested person.
ANYONE can become infested
with head lice, rich or poor, dirty or clean.
Lice are small,
grayish-white, wingless bugs (about the size of tiny ants). They cannot
fly, and they do not jump, but they do move very quickly. They lay oval,
whitish-silvery eggs called nits.
Nits are whitish eggs that
are attached to a hair shaft with a cement-like substance located close
to the scalp. They are not to be confused with dandruff, hair casts
(debris) or hair spray droplets which are flaky. Nits are attached to a
single shaft of hair and will not come off like dandruff. Nits are the
most common sign of lice found during screening.
Intense itching caused by
feeding of the lice is the other major symptom of lice infestation.
Lice and their nits are
usually found in the hairy surface of the scalp, behind the ears and at
the back (nape) of the neck, though they may be found on other areas of
the scalp.
Once lice infestation
starts, it can spread quickly. Prompt action requires ridding yourself
of this tormenting pest. Be sure to check all family members, especially
those who sleep with the infested child.
Lice and their nits can
survive, for a time, off the human host. It is very important that
infested persons and their personal articles that may be infested are
treated promptly.
TREATMENT
1. Several shampoos and
a prescription cream rinse to kill lice are on the market. Some can be
bought over-the-counter at your local drugstore, (ask the pharmacist for
name brands) but others require a prescription. 2. Remove all clothing and put clothing in a plastic bag. This may be done in the bathtub or shower stall.
3. Shampoo hair and
scalp with lice treatment product according to doctor's instructions,
label instructions or use the lice treatment cream rinse according to
the directions.
4. Put on freshly
cleaned clothes. Use clean towels and bed linens.
5. Comb hair well with
fine toothcomb. Rinse the comb after each area of hair is combed. Nit
combs usually are supplied with the shampoo or rinse. Removing nits
manually (pulling them out with fingernails) is the best option for
removal, especially when treatment products have failed. Be sure to
wash under fingernails after nit removal.
6. The U.S.
Government's Public Health Service recommends a second shampoo (with the
medicated shampoo) in 7-10 days to kill any (live) nits that were not
killed with the first treatment. Do not treat more than twice in one
week. Do not shampoo or put other products on hair between treatments,
and do not use regular shampoos containing conditioners.
7. Machine-wash all
washable clothing, hats, coats, etc. and bed linens, towels that were in
contact with anyone infested in the last 3 days. Wash using very hot
soapy water, dry and/or hot setting. You may also dry articles for at
least 20 minutes on high setting of clothes dryer for those articles
that cannot be washed.
8. Personal articles of
clothing or bedding, including stuffed animals, that cannot be washed or
dried may be dry-cleaned or left in a plastic bag and sealed for 7-14
days. 9. Soaking them in the special shampoo or cream rinse for an hour can disinfect combs, brushes and similar items.
10. Mattresses,
blankets, pillows, rugs, upholstered furniture and car seats need to be
treated. Vacuuming these articles will work. Lysol, Clorox or other
such cleaners do not affect the head lice or nits.
To
prevent the spread of head lice, persons should not share articles that
come in contact with the head, neck or shoulders such as combs, brushes,
hats, coats, towels, scarves, etc.
